Documentation

Short Descriptions Integrated in Product Documentation

The short descriptions of the different file formats of the PSS SINCAL Platform are now directly

integrated in the product documentation.

The following descriptions are available in the System Manual, chapter Technical Reference:

• PSS SINCAL PIC File

• PSS SINCAL Symbol Files

The following descriptions are available in the Database Description:

• Reliability Results in XML Database

• Optimal Network Structure Results in the XML Database

• Network Model with Admittance Matrix (NSN File)

Application Example for Grid Code Compliance Renewables according to VDE-AR-N

Comprehensive documentation is now available in the Power Flow manual for the "Example EEG"

network, showing how the module can be used.

The application of the function to assess the grid code compliance of a planned decentralized energy

resource (DER) is structured into the following steps:

• Preparation of the network model

• Configuration and run of the function

• Evaluation of the calculation results in the result view

• Creation of the documentation

Additional aspects for the modeling of equipment and calculation parameters are shown:

• Usage of operating points as base case

• Strategies to consider controlled equipment

• Access results and parameters

• Run the function via the API

Application Example for CSM Model

The documentation for the new example network "Example CSM" is available in the Dynamics

manual. The example illustrates the basic application of the time series and the stability calculation.

Depending on the targeted outcome of an analysis both methods differentiate in their timescales and

the model bases. PSS SINCAL provides the advantage to use the same user-defined models as well

as specifications related to the operating point in both calculation methods. On the other hand, the

example shows the extended modeling capabilities regarding global network models. These may

represent general evaluation functions, power system components (e.g. DC circuit of Multi-Terminal

HVDC) or centralized controls (e.g. virtual power plants, communication). In this example, a simple

command for power reduction is tracked from the transmission to the distribution level, considering the

delayed communication. The power system response is analyzed in different timescales. Thereby,

model parameters are consciously chosen, so that transients in stability simulation are visible and

comprehensible.


Release Information

April 2021 5/51

Application Example for Time Series Data Interface (TSDI)

The new example network "Example TSDI" shows a model of a symmetrical electrical network to

demonstrate the application of the Time Series Data Interface (TSDI) module.

The documentation for the example network is available in the Power Flow manual. This shows the

process for preparing the model for simulation, running the simulation and then evaluating and

accessing the results.

Application Example for Gas Networks

For the new example network "Example Gas" documentation is available in the Gas manual, which

illustrates the basics of network modeling as well as steady-state calculation, calculation of operating

points and time series and other aspects.

User Interface

General Improvements

This section presents general improvements in the user interface.

Advanced Dialog Boxes for Standard Types

The dialog box for displaying and editing the standard types has been extended. The dialog box can

now be resized so that the complete information about the standard types can be clearly displayed in

the browser (#1).

Also new in the dialog box is the status display at the filter button (#2). If an extended filter is active,

the button is highlighted.

Dialog Box for the Compilation of Reports

The dialog box for editing the report compilation can now also be resized to make the selection of

reports in the compilation even more convenient.

Network Archive

When opening network archives from older product versions, an information message is now

displayed, analogous to opening the network model directly, explaining that the model needs to be

updated.

Databases

Improved error messages when opening networks with MDB databases if the necessary drivers/ACE

redistributables are not available.


Release Information

April 2021 8/51

Excel Import

The Excel import function has been extended that it is now also possible to import neutral point

impedances.

Links to Other Views

The supplementary graphic object Frame can be used to define links to other views. This view is then

opened when the frame is double-clicked and the image section defined in the link is displayed. Here,

however, it can sometimes happen that the frame is moved in the original view in an undesirable way.

To prevent this, the new Lock object attribute is available in the properties. This can be used to

completely prevent interactive editing of the frame.

Tabular View

In the Tabular View, an extended function for selecting the network elements (#1) in the network

graphic is now available. If the complete row is selected, all available topology data is used to select

the matching network elements in the network diagram. If the row in the Tabular View then contains,

for example, information about the network level (#2) or the network area, all the network elements

assigned to this topology structure are also selected.

If this behavior is not desired, then only the cell with matching topology information is selected (#3).

Then only the network elements with matching topology data will be selected in the network diagram.


Release Information

April 2021 9/51

Forms for Entering Operating Points, Profiles and Characteristic Curves

The forms for entering characteristic curves have been extended. Multiple selection is now possible in

the browser. This means that the characteristic curves selected in this way can be easily deleted.

New Diagram System

PSS SINCAL offers a wide range of functions for performing time series-based calculations in

transmission, distribution, and industrial networks. The network models to be calculated are becoming

ever larger and the scope of analysis is also constantly increasing. In distribution networks, calculations

sometimes have to be performed over years at hourly intervals or even at quarter-hourly intervals. This

results in extreme data volumes for the diagrams, which require flexible data management.

Therefore, the diagrams were completely re-implemented in the two previous versions. The goals were

to improve performance by optimizing data structures and using new technologies to expand the

evaluation functionalities and to simplify operation.

With this version, this conversion of the diagram system is now complete. In PSS SINCAL 17.5, only

the new diagrams are available. These offer both the functionality of the old diagrams as well as many

extensions and the possibility for completely flexible use. In addition, the functionality of the diagrams

in PSS SINCAL and PSS NETOMAC is now largely identical, making it easier to work alternately with

both programs.

SQLite Result Database for Diagrams

The SQLite database system is used for persistent storage of the diagram data. This database system

can manage very large amounts of data and meets the performance requirements.

All diagram data is stored directly in the SQLite database by the PSS SINCAL calculation methods. A

separate SQLite database is generated for each variant. These databases are available in the network

directory in the folder "xxx_files\DIA". The file name of the SQLite database contains the ID of the


Release Information

April 2021 10/51

variant, e.g. "DIA\dia.001.db".

A special approach was chosen for storing the complex and extremely diverse diagram data, which

enables efficient use and visualization of the data in the PSS SINCAL user interface but can also be

used by external applications and automation solutions. I.e. external applications can also easily

access the data stored in the SQLite database and evaluate and process it further.

The following image shows the table structure in the SQLite results database as well as a simple query

of diagram data of the time series calculation:

The "Parameter" table contains general information about the database, including version identifiers

and information about the available data and calculation times.

The tables with the prefix "DB_" contain information on the structure of the tables in the database. They

contain readable names of tables and their attributes, the units of the attributes and additional

information for visualizing the data.

The other tables contain the actual diagram data. These are marked with the prefix of the calculation

method. In the example this is the internal identifier "LF" for the power flow calculation. The hierarchical

structure here corresponds to the usual structure of diagrams in PSS SINCAL:

LFPage … Diagram page as container for the data

LFGraph … Graph as container for the data vectors

LFVecData … Additional data for data vector

LFVoltageCurveNode … Diagram data as simple table

LFVoltageCurveElement … Diagram data as simple table

Signal Explorer for Managing the Diagram Data

The Signal Explorer is the central tool in PSS SINCAL for managing diagram data in the user interface.

It is activated via the menu item View – Signal Explorer. In the Signal Explorer, data from a wide

variety of sources that are suitable for display in diagrams can be visualized. By default, this is the

diagram data from the results databases, but in addition, data from other sources can also be


Release Information

April 2021 11/51

visualized.

Toolbar in Signal Explorer:

Filter

Insert a filter text for the Signal Explorer

Hide all and expand all

Help

The amount of data displayed in the Signal Explorer can be very large, depending on the calculation

method used. To facilitate navigation and selection, the data are displayed hierarchically. In the lowest

level, the different data sources are displayed. Then follows a structure based on the different

calculation methods. In the example, these are the time series calculation (LP) and the dynamics

simulation (DY). This is followed by further levels that further subdivide the data and at the end provide

access to the individual signals.

The Filter field can be used to easily and interactively restrict the data displayed in the Signal Explorer.

The use of wildcards ("*" and "?") is also supported here. As soon as a filter text is entered, only those

signals are displayed whose name matches the filter text entered. If a directory separator "\" is specified

in the filter text, only those signals are displayed whose directory path matches the filter text.

As soon as the desired signals are found in the Signal Explorer, they can simply be transferred to the

diagrams using drag & drop. Here, any compilations/combinations of signals of different calculations

in one diagram are also possible. The only requirement is that the signals have the same data basis

for the X-values. Then the arbitrary combination of signals from input data and different calculation

results is possible without any problems.

Changes in the Diagram View

In PSS SINCAL, the diagrams are visualized and evaluated in the Diagram View. During the conversion

of the diagram system, some old functionalities were removed, and many new things were integrated.

The objective was to make the diagrams even easier and more intuitive to use.


Release Information

April 2021 12/51

In the browser of the Diagram View (#1) only self-assembled diagram pages are now available, the

automatically generated predefined diagram pages do no longer exist. The data content in the browser

can be structured hierarchically by folders as desired. Then in the folders own diagram pages with

arbitrary format and content can be created. All data available in the Signal Browser can be used here

to interactively fill diagram pages with signals. In addition, a variety of new wizards are available to

automatically generate diagrams for a wide range of calculation methods.

An extended toolbar (#2) is also available in the Diagram View, which allows quick access to the most

important functions:

Toggle browser

Filter function in the diagram browser

Insert a filter text for the diagram browser

Compare variants

Create diagram pages

Formatting diagrams

Select objects

selected in the legend.

Wizards for Creating Diagram Pages

Various wizards are available for the automatic creation of diagram pages. These can be started via

the Diagram – Create menu, the toolbar in the Diagram View and via the pop-up menu in the browser.

In addition, the wizards are also available in the Signal Explorer.

The following table shows all currently implemented wizards. Whether they are available depends on

the input data as well as the results of the network model.

Release Information

April 2021 14/51

Here, in the input field Folder, the path is specified under which the new diagram pages are to be

created in the browser of the diagram. If the name of the directory begins with "\", then this is considered

as absolute path specification, otherwise the directory is a subdirectory to the current selection in the

browser of the diagram.

In the list Diagram pages those entries can be selected for which the wizard is to generate the diagram

pages. Depending on the diagram type, the Select data to be shown list is also available. Here the

signal quantities to be displayed can be defined. If the wizard is closed with OK, then the diagram

pages are automatically created for all selected entries.

In the diagram pages generated in this way, only descriptions, diagram formats and the information

about which signals are to be displayed are stored. However, the diagram page itself does not contain

any data of the signal. This data is dynamically loaded from the SQLite database when the diagram is

displayed. When the network is recalculated or input data is changed, the new signal data is

automatically displayed in the defined diagram pages.

Advanced Format Editor for Diagram Templates

The format editor for creating diagram templates has been extended with many new functions.


Release Information

April 2021 15/51

Layout functions for the diagram elements are now available (#1). This allows the elements to be easily

positioned and aligned on the diagram page. In addition, the most important graphical attributes of the

elements as well as their size and position can be edited directly in the Properties window (#2). This

allows exact positioning of the diagram elements on the page template.

Another new feature here is the ability to capture supplementary graphic objects (texts, lines, polygons,

etc.) on the diagram template.

Variable X Axis in Diagrams

Analogous to PSS NETOMAC, the free selection of signal values for the X axis in diagrams is now also

possible in PSS SINCAL. This means that, for example, locus curves (R over X) or the reactance curve

over the frequency (X over f) can be defined.

The definition of the X data values for a signal can be done in the Format Diagram dialog box. Here

there is the function to edit the signals in the diagram (#1). This opens the Edit Signal dialog box

where the data values for the X axis can be selected.

Display of Signal Positions in the Diagram

An extended display for the signal positions is available in the diagram. This means that the information

displayed in the legend for the data series can also be visualized directly in the diagram. The data

series object is used for this purpose. With the new tokens "&[EvalX]" and "&[EvalY]" this information


Release Information

April 2021 16/51

can be displayed in the diagram. When the signal position is changed, the information is automatically

updated.

Advanced Copying in the Diagram

The copying of signals in the diagram has been improved. Now, when copying all diagram signals, the

objects assigned in the diagram (markers, labels, etc.) are also considered. This means that a complete

diagram can be copied to another diagram page without any problems.


Release Information

April 2021 17/51

Electrical Networks


Redesign of the Calculation Settings

The Calculation Settings dialog box has been extensively redesigned to enable workflow-oriented

work. The parameters are now divided into the following three areas in the browser of the dialog box:

• Common:

Here you will find the general control parameters used by all calculation methods. With this,

essentially the global state of the network model can be defined. Defining extended settings for

the calculation methods is also possible here.

• Calculation:

Here the parameters for the different calculation modules like power flow, short circuit,

harmonics, etc. are defined. The scope of available entries here depends on which calculation

methods have been activated in the network model (Calculate – Methods menu).

• Results:

Here you can control how the results are generated. It can be defined, for example, which results

are to be stored in the network database and which in external databases. The control of the

output scope of the diagram signals is also possible here.

General Settings for the Network Model

The configuration of the network model for all calculation methods has been fundamentally revised. In

the newly designed Network Model tab is defined, in which this should be considered in the

calculations.

Here the View Date and Time field is important. This defines the start date for all further calculations.

If the date is not between the establishment and shutdown time of a network element, this network

element does not take part in the calculation. A time can also be specified for the calculation of a

specific point in time. The time for this is simply entered directly after the date in the input field. All

calculation methods that consider time series data start with this time.


Release Information

April 2021 18/51

In the Extended Network Model section, you specify which functions should be applied to the network

model before the actual calculation.

• The Consider Operating Point option defines whether the operating point (if selected) is

included in the calculation.

• The Consider Time Series Data option defines whether the time series are included in the

calculation.

• If the Consider Load Assignment option is active, an automatic load assignment calculation is

performed. In the following selection field, the procedure for the load assignment within the

calculation can be defined.

• The Consider Network Development option defines whether the future development of the

network model should be considered in the calculation.

The following flow chart shows how the different options are considered.

Completely new are the functions that can be activated in the Time Series Data Interface section.

These allow the simple connection of measured, estimated, forecast or planned values with a time

reference (time stamp) to the network elements. For this purpose, the time series data is made

available in the external database and read out and assigned to the network elements by PSS SINCAL

before calculation.

• Use the checkbox in this section to enable/disable the use of the TSDI database.

• Via the TSDI Database selection field the database to be used can be selected. The available

time series databases must be linked beforehand via the Insert – Time Series Database menu.

• The field Default Substitute Values controls the handling of missing values or values marked


Release Information

April 2021 19/51

as "Quality not assured", which are read in from the time series database via the TSDI. Here you

can choose between different settings (e.g. "0" insert, input data from network model or input

data incl. profile from network model).

Parameters for the Output of the Results

To define the scope of results of the different calculation methods, the Results tab is available in the

Calculation Settings dialog box, where the corresponding control parameters are clearly provided.

In the Database Results section, you can define how the results are stored. The selection field Store

Internal can be used to reduce or completely prevent storage in the network database, especially for

calculation modules that produce very large results (e.g. time series or motor start-up). Optionally,

these results can also be stored in an external results database. This is parameterized with the Store

External selection field.

In the Diagram Signals section the range of results is controlled for those calculation modules that

output results in the form of signals. These include the motor start-up, time series, network

development and harmonics modules. The following options are available here:

• None:

PSS SINCAL does not create any signals.

• Completely:

PSS SINCAL creates all the individual signals for nodes and element, profiles and network

results.

• Marked:

PSS SINCAL creates individual signals for marked nodes and elements, all profiles and network

results.

In the Settings for Result Creation the output of the power flow results can be parameterized. The

following options are available here for the time series calculation:

• Standard:

All time points are calculated and the results of all time points are made available.

• Worst Case:


Release Information

April 2021 20/51

All time points are calculated, but only the result value representing the "Worst case" for the

respective node/busbar or element is stored and then made available for evaluation. Here, the

highest utilization values are stored for the network elements and the largest exceedances of the

voltage limit values are stored for the nodes.

External Results Databases with MRID

For calculation methods whose results are stored in external result databases, the Master Resource

IDs (MRIDs) (if available) are now available in addition to the name and the Element_ID.

Also, the calculated variant is available as an entry in the external databases.

This facilitates the evaluation of the results and can be done by external applications more

independently from the knowledge of the network model database.

Display of Input Values and Results in Reference Values [pu]

The visualization of input data and results in reference values is now available as an option in the

network graphic, the data screen forms and the Tabular View.

In addition to the display of input data and results for impedances in absolute form with unit Ohm (#1),

a display in relation to reference values (per unit [pu], #2) is also usual. The reference value is

determined by means of the assigned rated voltage and the reference power.

The display of impedances can be activated either individually in the labeling of the network graphic,

the data screen forms and the Tabular View or for the complete application.

Rated power: 100 MVA Network level rated voltage: 20 kV


Release Information

April 2021 21/51

Power Flow (PF)

Improved Control Settings

The control settings for the power flow calculation have been revised. All control settings are now

directly available in the dialog box. Here you can globally activate/deactivate the control in the power

flow and control whether tap positions are processed discretely or continuously (#1).

The parameters for detailed control were divided into the areas Controlling Elements and Controlling

Power Flow Algorithm (#2). The control of the elements is performed directly on the network element

in each PF iteration, when this is processed according to the set operating point. The control in the

power flow algorithm occurs after all individual element controls, when the power balance in the power

flow is checked.

Revision of the Global Power Flow Results

The various global results of the power flow calculation, which were previously available in many

individual results screen forms under Calculate – Results, have been revised and are now all

integrated in a new browser. Now it is easy to switch between the different results without having to

close dialog boxes and reopen them via the menu. The browser can be opened via the Calculate –

Results – Power Flow menu.

In the browser, the results are divided into the following sections:


Release Information

April 2021 22/51

• Common Results:

All power flow results for the entire network are available here. This includes, among other

things, the results for the accuracy, the power data, the power balance and also those of the tap

positions.

• Area Results:

Extended results on network areas and for transfer powers between network areas are available

here.

Operating Point and Time Series Calculation (LP)

In the operating point and time series calculation some new functions are available and also the control

of the calculation and result output has been made clearer. When starting the calculation module, a

control dialog box is now no longer displayed. All settings for the calculation procedure are anticipated

directly in the Calculation Settings dialog box in the Network Model tab. The configuration of the

results is also done via this dialog box. The new Results tab is used for this purpose. In this tab it is

now also possible to set whether the time series calculation saves the complete results or only the

worst case (#1).

Advanced Signals for Network Element Losses

In addition to the existing result signals, the serial and cross losses are now also recorded for all

network elements in the time series calculation. These are available in the Signal Explorer for the

network elements.

Advanced Signals for Power Balance

For network levels and network areas, the following new result signals are provided under power

balance in the time series calculation:

• Active power from generators and consumers

• Reactive power from generators and consumers

• Active power losses

• Reactive power losses

New Signals for Temperature Profiles

Temperature profiles of overhead lines, cables and transformers, which can be assigned to network

areas, are now also available in the form of signals in the time series calculation. These are provided

in the Signal Explorer at the network areas.


Release Information

April 2021 23/51

New Signals for Measuring Devices

For measuring devices, the following signals are made available in the Signal Explorer in the course

of the time series calculation:

• Active and reactive power at the installation location of the measuring device of the power flow

• Active and reactive power for consumers at the measuring device

• Active and reactive power for supply sources at the measuring device

Load Assignment (LA)

The load assignment calculation module has been comprehensively extended. The aim was to make

the existing module even more flexible to meet the various requirements in the integration of the

method with other calculation types (e.g. the time series calculation LP) and still allow easy use.

The load assignment is based on the assignment of measuring devices to terminals, which specify the


Release Information

April 2021 24/51

operating state of the network at these points. The following figure shows a simple network with

measuring devices and consumers for load assignment:

All network elements "underlying" to the measuring device influence the power flow result. A distinction

is made here between consumers and supply sources. For both, it can be configured whether they

participate in the load assignment or not. For those network elements that participate in the load

assignment, the power in the calculation module is varied in such a way that the specifications of the

higher-level measuring device are achieved.

Previously, only loads and DC infeeders could be considered in the load assignment. To provide

greater modeling freedom in the networks, the following network elements are now considered:

• Load

• Variable shunt element

• Asynchronous machine

• Synchronous machine

• DC infeeder

The trimming or scaling of consumers and supply sources is now only based on the values entered for

measuring devices in the Assignment Data tab and the basic data of the individual elements.

For loads it is now possible to parameterize whether the sign reactive power (ind./cap.) may change

during trimming in order to distribute the reactive power to the elements depending on the selection

(ind./cap.).

The trimming algorithms have been extended and improved. The aim here was to enable trimming with

high quality and good performance in both balanced and unbalanced networks.

The parameterization of the network elements for this calculation module has been separated from the

transformer tap detection. The input data for transformer tap detection are now included in the

Optimization tab and this calculation module is also connected to the activation of optimization

(Calculate – Methods).

New Data Input for Measuring Devices

The data input of the measuring devices was generally revised to better structure the input data.

Now the following four tabs are available in the data screen form of the measuring device:

• Basic Data:

Topology data of the measuring device and its status.

• Additional Data:

Information about the assigned master resources.

• Assignment Data:

Data for consumers and supply sources for the load assignment calculation module.


Release Information

April 2021 26/51

• Fault Locator:

Fault recorder values for fault location.

New Symbols for Measuring Devices

New symbols are available for measuring devices for display in the network graphic. These can be set

individually per measuring device via the Format dialog box or via the Properties window:

Display of Measured Values in the Network Graphic

For measuring devices, the load assignment data can now be visualized in the network graphic. This

is the data that is used as a default for trimming the underlying loads and supply sources. The display

of results for measuring devices can be activated in the Annotation and Filter dialog box.

The new results for measuring devices are available for all calculations where load assignment is

performed. This also includes the time series calculation. Here, the new result is then made available

for each calculation time. This makes it particularly easy to compare the result of the trimming at the

terminal of the network element with the specifications from the measuring device, even if the

measuring data are assigned via profiles.

Hosting Capacity (ICA)

The Hosting Capacity calculation module has been enhanced to make it even more flexible to use.

There is now a clear separation of the connection points from the analysis area. The following applies

here:

• Connection Points:

Nodes where the installation of a generating unit or a consumer is to take place.

• Analysis Area:

Set of network elements and nodes and network elements on which compliance with the criteria

is checked.

This separation is also found in the wizard that is opened when the calculation module is started. The

connection points and the analysis area are parameterized on two separate pages. The two sides offer

largely the same setting possibilities, so that alternatively here connection points and analysis area

can be selected the same or also differently.

The basic configuration is done with two setting options. In the list with Network Levels (#1) it can be

selected for the whole network model which network elements and nodes are considered. The second

setting option is used to define the area in the network model. The selection is made directly under the

list with the Network Levels (#2). Here you can choose between a Network Area or a Network

Element Group. In the end, only those possible connection points or for the analysis those nodes and

network elements are considered, which are contained in the respective defined network area or

network element group and are assigned to one of the selected network levels.


Release Information

April 2021 28/51

Energy Storage Placement and Sizing (ES)

The configuration for this calculation module has been changed analogously to the hosting capacity

module. Here, the connection points and the analysis area can now also be defined independently of

each other.

Short Circuit (SC)

Dynamic Voltage Support

The increase in short circuit contribution of converter-based generation requires a simulation model

that reflects a voltage dependent reactive current injection for short circuit calculation and protection

analysis. For example, such an action is required by VDE-AR-N 4110/4120/4130 and Engineering

Recommendation G74 Issue 2.

The dynamic voltage support function allows engineers to simulate the short circuit contribution of the

converter by a reactive current injection dependent on the voltage drop at the connection point. As

such, the dynamic voltage support characteristic can be adjusted and the positive and the negative

sequence system are supported.

Dynamic voltage support can be activated for the DC Infeeder in the System Data tab in the Short

Circuit Data section:

Protection Coordination (OC, DI, PSA)

Import and Export Protection Device Settings

With these functions, all setting values of protection devices can be exported to an XML file (sincase).

This makes it possible to save a wide range of variations of protection device settings and to import

them again later. This allows the management of different parameter sets for individual devices, but

also creates the possibility to create setting value templates.

The new functions are available in the menu under File – Export – Protection Settings and File –

Import – Protection settings. This allows the setting values of all protection devices in the network

or those of the selected protection devices to be exported or imported. In addition, both functions are

also available directly in the pop-up menu of the protection devices under the menu item Import and

Export.

Protection Analysis with Scenarios in the Multiple Calculations

The multiple calculations with scenarios available in PSS SINCAL have been extended specifically for

use with the Protection Analysis (PSA) calculation module.

A scenario is a set of change information assigned to an existing network model. This can be used to

change the operating state of the network elements (active/inactive), switching of the connections and,

of course, the individual data of the network elements (e.g. powers, factors, control settings, control

method, etc.).

Exactly these changes in the network state can have significant effects on the correct functionality of

the protection and this can now be checked in a largely automated way with the multiple calculations.

For this purpose, the calculation module is started via the menu item Calculate – Multiple

Calculations. The Scenarios calculation mode is then selected in the control dialog box. Now the

Protection analysis module can be selected in the dialog box. Individual parameterization is possible

by clicking the Settings button (#1). Then the control dialog box for the protection analysis is opened

and the desired settings for the calculation module can be made there in the same way as in the dialog

box that is displayed when starting directly the PSA module.


Release Information

April 2021 31/51

Clicking the Calculate button starts the calculation of the selected calculation methods with all

available scenarios. For each scenario, a variant is created that contains the modified network model

and the results of the calculation methods are then saved in this variant. The complete results of the

protection analysis are then available.

General Performance Improvements

The calculation of the fractions of the short-circuit current has been made more flexible. The fractions

no longer must be determined directly in the short-circuit calculation, which has significantly improved

performance in calculations such as protection analysis, protection distances, etc.

Enhanced Impedance Area Pickup

The area pickup has been extended by new shapes of areas and the new Load Cut Out section (#1).

Now the pickup areas of the MICOM P43x and P44x devices as well as ABB Relion series 500 and

600 can be simulated.

Release Information

April 2021 33/51

The shape of area Quadrilateral – Form A is a special area (based on MiCOM protection device

areas). It is not possible to select the load cut out for this area, but the load cutout can be limited by an

arc:


• Setting R (value must not be ZERO)

• Setting Forward/backward ratio (value must not be ZERO)

• Setting Alpha (value must be between -45° and +45°)

• Setting RLF (value must not be ZERO)

• Setting PhiLF (value must be between -90° and +90°)

New Distance Protection Device SEL311-L1

The SEL311-L1 distance protection device is now also available in PSS SINCAL. This is a digital

protection device with settings R, X, Z, angle φ. The tripping area is a diamond-shaped impedance

quadrilateral, an MHO circle or a polarized MHO circle. A setting α can also be defined for zone 5 and

zone 6.

Enhancement for the 7SA632 Distance Protection Device

For the 7SA632 distance protection device, the range of the reactance in the backward direction is now

available as a separate setting parameter for zones 5 and 6.

Distance Protection – Measurement Loop Detection based on Phase-Selective Pickup

The phase-phase measuring loops are only used for selection if a minimum current is exceeded in

both phases. The phase-ground measuring loops are only used if the earth fault detection is positive,

and a minimum current is exceeded in the phase. The minimum current is taken from the set pickup.

Measuring Loop Selection without Minimum Current

If no minimum current is specified, e.g. if no pickup is set, the rated transformer current is used as the

minimum current for the measurement loop detection (railroad networks are excluded from this).


Release Information

Enhancements for Teleprotection

The teleprotection has been enhanced for voltage and frequency protection. Now these zones can be

used both as receivers and transmitters in teleprotection.

There is also an enhancement for protection devices that are out of service. All teleprotections defined

for these devices are now automatically deactivated in the calculation. There is then no longer an error

abort if deactivated devices with teleprotections are in the network model.

Grading Diagram Distance Protection

The grading diagrams for the calculation of the DI settings and the protection distance calculation now

show the directional and non-directional end time. All types of pickup are supported here.

Enhancements for Protection Documentation

In the It diagrams of the protection coordination, the reference voltage level for the current can now be

freely selected. The voltage is set in the Format Diagram dialog box with the Reference value option.

This voltage is then used to convert the current values displayed on the axis accordingly.

The display of the legend in the diagram pages of the protection documentation has also been

extended. Now a legend is also available for fuses, which visualizes the characteristic data of the fuse.

Grid Code Compliance Renewables (EEG)

The module Grid Code Compliance Renewables was further improved and expanded. The new

functionalities are largely based on users' ideas/feedback from user group meetings, feedback from

support and ideas deposited in the Ideas Portal (PSS® Ideas Portal).

Restriction of the Analysis Area/Exclusion of Function Groups

With these new functions, it is now possible to configure in detail which network elements are to be

considered when verifying the connection conditions. The objective here was to combine the greatest

possible flexibility with simple usability.

The new section Analysis area (#1) is available in the Network State tab.

The Type selection field can be used to define the area to be checked. The following options are

available:

• Network topology:

https://pss.ideas.aha.io/portal_session/new


Release Information

April 2021 37/51

No limitation of the area (previous functionality).

• Network area:

The area is reduced to those network elements that are assigned to the selected network area.

• Network element group:

The range is reduced to the network elements contained in the selected network element group.

In addition, it is also possible to use the Excluded group option to select a network element group

whose network elements are explicitly excluded from checks.

With the DER function groups option in the analysis area, the identification of existing plants can be

controlled separately from the option in the network area also for the analysis area. The combined

elements of a function group are considered as one generation plant when Consider is selected.

Treatment Element Controller Fast/Slow Voltage Change

An option can now be used to control whether the element control is held after the first power flow

(reference power flow) or not. This is to be selected separately for the slow (#1) and the fast voltage

change (#2).

The Controller in network option during voltage change checks is a non-procedural functionality. This

option supports the procedure to achieve better and realistic results. The following selections are

available here:

• Hold

• Active

When controlling an element, a manipulated variable is changed due to a condition to be achieved. If

Active is selected, the control in the network is included in the calculation without restrictions. With the

Hold selection the manipulated variables of the network elements to be controlled are held.

The manipulated variables are as follows:

• Regulator:

Discrete position (e.g., for two-winding controller – transformer controller)


Release Information

April 2021 38/51

• Operating state:

Continuous manipulated variables for active power and reactive power (e.g., synchronous

machine – power control)

Depending on the manipulated variable (regulator or operating state), the control of the network

element is maintained according to the first power flow (reference power flow). Here, the operating

state (P and Q) or the current tap position is adjusted accordingly. This makes it easier to determine

the voltage change between two power flows.

For the fast voltage change, this can be used to simulate that the control of existing plants in the

network does not intervene immediately after the new plant is switched off or on.

Treatment of DER with Internal Transformers

If a DER is modeled with an internal transformer, it is now considered as a generation plant. Here it is

important to note that the internal node (primary side of the transformer) is ignored when evaluating

the results.

Treatment of DER with Separate Transformers

Generation plants that are not connected directly but via a transformer are considered. Normally, these

would not be considered, since the network area for determining the connection conditions ends at

transformers.

Creation of Word Documentation

For verification according to VDE-AR-N, the (automatically generated) Word reports have been revised

and are available in German and English.

The automatic generation of Word reports is no longer available for verification according to NER or

IEEE.

Documentation with Application Example

For the example network "Example EEG", comprehensive documentation is now available in the Power

Flow manual, showing in detail how to use the calculation module.

Power Flow Results for Dynamics Simulation

When simulating in the time domain (stability or electromagnetic transients), it is now possible to

parameterize whether the power flow results are to be written to the results tables of the PSS SINCAL

network database here. For this purpose, a new control option (#1) is available in the Dynamics tab

of the Calculation Settings.

Enhanced Support for Lines/Cables with Coupling Data

The processing of lines with coupling data has been extended. So that couplings can be correctly

considered in the calculation, they must be defined very precisely (with many decimal places).

However, this is a problem when exporting to the NET file of PSS NETOMAC if the fixed data format

is used. Therefore, this data is now exported in the free data format. This is not well readable but has

no problems with loss of accuracy.

or completely prevented, it is not possible to maintain the pressure at the outlet node in every network

situation. Due to the new functionality, it is now no longer necessary to add further network elements

(e.g. check valves) downstream of the pressure regulator in order to prevent return flow.

The second new functionality is available in both water and gas networks. A limit value for the

Maximum Flow (#2) can be specified. If a value unequal zero is entered here, then this is also checked

in the calculation. The calculation result (Q) for the branch element is then compared with the limit

value and evaluated as a result. The violation of limit values is logged in the Status field and the

exceeding of the limit value Q/Qmax is shown. These new results are available in the network diagram,

the data masks and in the Tabular View.

Infeeder in Gas Networks

A limit value for the maximum flow can now be specified for the network element in the same way as

for the Pressure Regulator.

Time Series Data Interface (TSDI)

PSS SINCAL has a wide range of different simulation methods for which, in addition to the topology of

the network itself and the parameters of its operating equipment, suitable boundary conditions and

input data for the modeled elements (e.g., network feeders, consumers, planned switching operations)

are required at the respective points in time or observation periods.

The new Time Series Data Interface (TSDI) offers an interface to an open generic time series

database. This facilitates the cooperation between operation, metering and planning teams by

integrating time series data (like measurements, forecasts or schedules and switching events) into the

initial condition for all power flow-based analyses or into a complete time series simulation. This

leverages the investment in metering, SCADA and forecast systems for grid analysis and planning use

cases.

The following figure shows how the time series data interface is basically integrated in the architecture

of the PSS SINCAL Platform.

The time series data in the external database is provided by an application outside the PSS SINCAL

Platform before the simulation. For this purpose, the structure of this database is generically predefined

and can be filled from any number of sources.

The PSS SINCAL simulation uses the PSS SINCAL network model to prepare the calculation. During

the runtime of the calculation, the input data for linked elements of the network model are then taken

from the time series database (SQLite database) for the points in time to be calculated. This is done

via the Time Series Data Interface (TSDI).

Interaction with the Input Data of the Network Model

The input data (e.g., power values for electrical loads, voltage and power specifications at generators,

consumption values at consumption points in pipe networks, breaker or valve positions) can be taken

from two different sources:

• On the one hand, these input data are taken from the network model (and thus from the network

database or the network data files). By default, the input data available in the network model are

also the data for the calculation.

• On the other hand, an extraction of the input data from an external time series database via the

Time Series Data Interface (TSDI) is possible if a connection exists for the respective element to

the external source (also an open database). The input data from the network model are then

only used complementarily and complete or replace missing data from the external database for

all or individual points in time.

Integration into the Existing Calculation Procedures

The integration of the use of the TSDI (i.e., the use of the external time series data) is fully integrated

into the existing calculation modules and allows the following procedures and use:

• Power flow calculation at a defined point in time using the external time series data for exactly

this point in time. Only the calculation for this one point in time is performed.

• Power flow calculation at different, non-consecutive defined points in time using the external time

series data for exactly these points in time can be done using the application programming

interface (API).

• Time series calculation for a time period (several, consecutive points in time) using the external

time series data for the mapped elements (linked via MRIDs) and the internally modeled and

assigned profiles for the unmapped elements. Both approaches, the use of time series data on

the one hand and the use of cyclic profiles (e.g., standard load profiles) on the other hand, thus

run in parallel.

• Use of time series data for basis power flow in advanced calculation modules, e.g., Contingency

Analysis (module CA) or Stability (module ST).

Structure of the Time Series Database

The generic time series database was designed to be as simple as possible about its use by external

applications. This is to simplify filling by external applications to a large degree.

The following figure shows an overview of the tables of the time series database for electrical networks:

The central table here is Topology. The table contains the mapping to the PSS SINCAL network

elements. Thus, the linking of the measurement data to the network elements is done via the MRID.

The DataState table includes the operating state of the elements and for the elements of electrical

networks also switching positions and discrete controller positions.

For use with electrical networks, a distinction is made according to the mode of action of the elements

elements (DataPV) and for current values of measuring devices (DataI).

For use with pipe networks, the DataConsumer table is available for consumption services or

quantities, and the DataSupply table is available for feeding elements.

The Parameter table consists of a primary key (Parameter_ID), a category, a name and a value. This

table specifies the type and version of the time series database.

Documentation and Application Example

Comprehensive documentation is available in the Time Series Data Interface (TSDI) chapter of the

Database Description.

The new example network "Example TSDI" shows the application of the Time Series Data Interface

(TSDI) module. The documentation for the example network is available in the Power Flow manual.

This shows the procedure for preparing the model for simulation, running the simulation, and then

evaluating and accessing the results.

Replacement Function Smart Load Flow (SLF)

The new Time Series Data Interface (TSDI) replaces the Smart Load Flow (SLF) previously available

in PSS SINCAL. The solution used so far, based on a COM API, offers neither the performance nor

the functionality and flexibility in the configuration of the new TSDI.

Calculation Methods


Extension of the Array Functions

In PSS NETOMAC, a new input block (INPUT 040000) has been available since version 17.0, which

allows access to all node results and those from all machines.

The following example shows the functionality:

$1......12......23......3AA1....12....23....34....45....56....67...78...89...9ZZ arVal EndInd INPUT 040000 nB 1 $ Print all voltages and names from result array DO n = 1, EndInd Value = arVal(n,1) Index = arVal(n,2) s:Nam = NAMIDX(1,Index) $ FORMAT n Index Value s:Nam ('n, Idx, Val, Name: ', 2(F5.0,','), F8.3, ', ',A10) FEND ENDDO $ $1......12......23......3AA1....12....23....34....45....56....67...78...89...9ZZ $ Get minimum and maximum values from result array IF(EndInd.GT.0) THEN IdxMax = MAXLOC(arVal,1) ValMax = arVal(IdxMax,1) Index = arVal(IdxMax,2) s:Max = NAMIDX(1,Index) $ IdxMin = MINLOC(arVal,1,>.4) ValMin = arVal(IdxMin,1) Index = arVal(IdxMin,2) s:Min = NAMIDX(1,Index) PRINT IdxMaxValMaxs:Max IdxMinValMins:Min ENDIF $

With the input line in the example the amount of the node voltage is transferred into the array arVal

(Name1). The array is 2 columns wide and contains as many lines as matching nodes were

determined. The number of lines is returned in EndInd (Name2). A DO loop can be used to access the

individual values of the array. The selected output value is available in the 1st column, the internal index

for the node name is available in the 2nd column. With the internal index of the node name the actual

node name can be returned as text. The NAMIDX function is available for this purpose.

Now the new function IDXNAM is available, with which the index in the array can be determined based

on a node name or machine name. This can be useful if the evaluation in the model is not to be carried

out here for all data present in the array, i.e. if the name is already known:

$1......12......23......3AA1....12....23....34....45....56....67...78...89...9ZZ $ Get index in array by its name s:Nam = 'N101' nNam = IDXNAM(1,arVal,s:Nam) Value = arV(nNam,1) $

New Functions for Plotting Output at EMT Simulation

values or space vector.

And now the output as a space vector:

A rotating coordinate system is always used for the output as a space vector. Therefore, real and

Instantaneous Values in EMT at Input NET_RE

In GMB models and in BOSL models, the instantaneous value of the voltage is now transferred to the

model for the input variables for the voltage amount RVMAG in the EMT simulation. This is done if the

phase is defined when using the model.

The following picture shows a section of a GNE-PQ model which has three remote inputs (Y1, Y2, Y3)

for voltage values.

If the phases are defined when the model is used, then the instantaneous values are transferred to the

inputs of the model during simulation.

Mirroring Input and Output Blocks

In the Model Editor it is now possible to mirror the input and output blocks. This is to enable a more

April 2021 50/51

The functions for mirroring the blocks are available in the pop-up menu under Rotate – Flip

Horizontally and Rotate – Flip Vertically as well as in the Properties window.

New Mode for Alignment of Connectors

In the Model Editor, the function for automatically aligning connectors has been improved. The new

Layout Mode 2 can now be activated in the Model Editor Properties window. The new mode uses

advanced algorithms to try to align the connectors between the blocks as orthogonally as possible.

New Controller Types GREF and VREF

Two new controller output variables are now available in the Model Editor:

Set-Point Speed Controller
