1 Introduction

The description given in this document covers the design of the Vestas PSS/E wind turbine

user written model. The model is applicable to all Vestas GridStreamer TM wind turbines.

This document is a user manual that explains how to implement the Vestas GridStreamer TM wind turbines in an existing grid and states a number of steps that must be performed to geta successful simulation.

The document is a general overview of the PSS/E user written model version 8.0 for VestasGridStreamer TM wind turbines. The model is developed for the purpose of dynamic stabilityanalysis and therefore generally omits effects with time constants shorter than one AC cycle. A PSS/E time step (DELT) in the range 1ms to ½ cycle is recommended.

Vestas PSS/E Model Package

This user manual is part of a model package including the following files:

2 Vestas GridStreamer TM

Model

This PSS/E user written model has been developed to support the Vestas GridStreamer TM wind turbines topology. This is explained – in short - in the following sections.

2.1 Vestas GridStreamer TM ConceptIn the full-scale converter system the generator is decoupled from the grid-side convertercompletely by the DC-link. In this case the converter will be in total control of the powerand the GridStreamer ™ WTG is coupled via a step-up transformer to the connection point.

2.2 Model Structure

The PSS/E user written model developed for the Vestas GridStreamer ™ wind turbine is asimplified ‘dynamic’ model of the WTG and omits some detail of mechanical componentsand the generator-side converter. However, this model was shown to accurately representthe complete GridStreamer™ turbine, because the mechanics and generator -side con-verter have very little impact on the grid-side output due to decoupling through the DC-link.

Figure 1 shows the generic model structure for Vestas GridStreamer TM wind turbines.Here the various signals and blocks may be observed as well as input and output of themodel. Note that the grey blocks are not part of the PSS/E model, and have directfeedthrough signals.

As mentioned in the Introduction, this model is intended for grid dynamic stability analysis.It may also be designated as a performance model, since it receives grid voltage and fre-quency and delivers active and reactive power as response.

2.3 Model FeaturesIt is important to decide the types of analysis and studies needed to be carried out beforedeciding which approach to use in modelling the physical system. The modelling approachshould reflect the intended types of analysis and studies.

These questions led to shape the modelling requirements and to give a better overview ofthe user’s needs in order to develop an analysis-dedicated model. The modelling of thewind turbine needs to be made according to the performance of the simulation tool, whichis the PSS/E.

The pre-modelling analysis has been done for using PSS/E simulation tool and the out-come is listed in Table 1.

3 Simulation Preparation

This section explains how to add Vestas Wind Turbines Model and modify the user’s exist-ing system simulation files. With the package files provided by Vestas Wind Systems A/S,the end users should modify their load flow data (RAW or SAV file) as well as their dynam-ic data (DYR file). The suggested modifications are stated below.

3.1 Load Flow DataThe PSS/E user should begin by preparing a solved load flow case which includes a gen-erator and unit transformer for each WTG or WTG aggregate.

-The WTG’s Generator :

The wind power plant units can be included as separate units or as a single aggregatedgenerator, with appropriate steady-state real power (P) and reactive power (Q) for eachwind power plant (turbine). The relevant WTG generator should be implemented by theuser according to the parameters listed in Appendices and the set up instructions in Chap-ter 6.

NOTE : In newer versions of PSS/E a generator is added to the load flow case as either a‘classical machine’ or a ‘wind machine’. The Vestas wind turbines should be added as a

classical machine not a wind machine, as the model is designed to be back compatible toPSS/E version 29.

- The WTG’s Transformer :

In addition to the substation transformer, a step-up unit transformer should also be includ-ed in the load flow case by the user. The delivered model package does not include theWTG transformer and therefore this transformer should be implemented by the user ac-cording to the parameters of the transformer as given in Appendices and the set up in-structions provided in Chapter 6.

The user may refer to the raw file template in Template 1.

3.2 Short Circuit DataUnder fault conditions the behaviour of the WTG is determined by the converter control.During a fault the converter controls will limit the magnitude of the fault current contributionto 1.05 p.u. (Ik”) and 1.45 p.u. (peak) on WTG rated current.

The WTG should be modelled as a current source for short circuit studies. The currentsource should contribute a maximum of 1.05 p.u. (Ik”) fault current.

In PSS/E the value of Zsource is obtained from the maximum short circuit current contri-bution (Ik”=1.05 p.u.). The recommended values are listed in Appendices and the set upinstructions provided in Chapter 6.

3.3 Dynamic DataThe user should prepare a DYR file (.dyr) containing the dynamics data. This will generallyinclude dynamic data records for other power system plant(s), as well as the dynamic datafor Vestas WTG model. In this package the user will find a parameter template(V<xx>.GS.<yy>MW.<zz>Hz.Mk<k>.Df.v8.0.n.dyr) as shown in Template 2. The template

for different Vestas GridStreamer

wind turbines can be found in Appendices.

The dynamic data file (DYR file) Template 2 supplied requires user modification, to insertthe details specific to each WTG. If there is more than one WTG in the PSS/E simulation,the user should duplicate the DYR file contents for each WTG added, and to modify each

of the user inputs denoted by the “<>” to reflect the particulars of each WTG. User inputparameters are listed in Table 2. The details that must be entered by the user for eachWTG are:

The PSS/E bus number (<bus>) and machine ID (<mach>) corresponding to thesingle or aggregate WTG generator.

The WTG reactive power control mode (<WTGmode>): 0 for direct reactive power(Q) control, 1 for power factor (PF) control.

4 Simulation Procedures in PSS/E

The model is developed for a maximum simulation time step of half a cycle. The model isdeveloped for PSS/E versions from 29 upwards.

The wind turbine(s) impacts on the system (grid) will be dependent on the short circuit ratio(SCR) and X/R at the bus to which the wind turbine(s) is (are) connected. In this sense it isvery important to assess the model performance taking into consideration the grid strengthseen from the connection point.

Section 4.1 gives the recommended settings for the dynamic simulation. In Section 4.2,the simulation procedure is given (dependent on the version of PSS/E). The list should befollowed exactly in order to get a successful simulation.

4.2 Simulation Steps

Simulation steps: PSS/E version 29 to 31

1. Create a working directory – where files related to this simulation set-up shallbe placed – including all relevant files listed.

2. Start up a command prompt in the working directory, ensuring the PATH isset correctly to be able to run PSS/E programs.

3. Start-up PSS/E dynamics (PSSDS4) in the working directory.4. Enter PSS/E load flow (LOFL).5. In case the user’s preferred method of representing the load flow case is a

raw file then read the load flow raw file (READ) to which the Vestas wind tur-bines have been added. If the user prefers to use an already created savedcase then open (CASE) the load flow case to which the Vestas wind turbineswill be added.

6. In case the user has chosen to use a Saved file (*.sav) then the following maybe necessary:

i. Modify this load flow case by adding the desired number of new buses,feeders and transformers necessary to model the WPP collector sys-tem up to the point of common coupling with the existing power sys-tem.

ii. Add the WPP aggregated generator(s), specifying P and Q output foreach.

iii. Add the wind turbine transformers as per the implemented structure:1. Aggregated transformer for aggregated WTGs (if applicable).

Simulation steps: PSS/E version 32 and above

1. Create a working directory – where files related to this simulation set-up shall

be placed – including all relevant files listed.2. Ensure the system PATH is set correctly to be able to run PSS/E programs

(using the PSS/E Environment Manager if necessary).3. Start-up PSS/E in the working directory.4. In case the user’s preferred method of representing the load flow case is a

raw file then read the load flow raw file (READ) to which the Vestas wind tur-bines have been added. If the user prefers to use an already created savedcase then open (CASE) the load flow case to which the Vestas wind turbineswill be added.

5. In case the user has chosen to use a Saved file (.sav) then the following maybe necessary:

i. Modify this load flow case by adding the desired number of new buses,feeders and transformers necessary to model the WPP collector sys-tem up to the point of common coupling with the existing power sys-tem.

ii. Add the WPP aggregated generator(s), specifying P and Q output foreach. Ensure the g enerator(s) spec ify ‘not a wind machine’.

iii. Add the wind turbine transformers:1. Aggregated transformer for aggregated WTGs (if applicable).2. Separate transformer for separate WTGs (if applicable).

6. Solve the load flow case and save the solved case file.7. Convert the load flow case for dynamic simulations by using CONG and

CONL, followed by ORDR, FACT and TYSL.8. Make a copy of the relevant DYRE parameter template, and fill in the details of

each WPP. Add the DYRE records to any records for other system plant tocreate a system wide ‘.dyr’ file.

9. Read (DYRE) the new ‘.dyr’ file, and specify CONEC.FLX and CONET.FLXfiles, and a name for the compile-file as appropriate.

10. Save the snapshot.11. Use the ‘Create User DLL’ function in the Dynamics menu to compile the

CONEC and CONET subroutines and link the model code into PSS/E. Specifythe library ‘VestasGS_8_0_n _PSSE32.lib’ when r equired.

12. You are now ready to run simulations: enter PSS/E dynamics (PSSDS4), openthe snapshot and load flow case.

Note : It is not necessary to specify the WPP real or reactive power output in the *.dyr fileas these will be taken from the load flow case at initialization (i.e. when using the activitySTRT).

Once the snapshot is taken and the model compiled and linked, the same dynamics snap-shot can be used with multiple load flow cases, provided the network topology and con-nected models did not change from one case to another. It is therefore possible to assem-ble a number of load flow cases, each with a different level of initial WTG power outputand/or voltage, without reassembling the snapshot or recompiling before using each differ-

ent case in a simulation.

5 Vestas System Example

5.1 System ModelVestas has built a simple example to show how to setup and simulate with the WTG mod-els. The test grid is modelled with four buses and two branches, with the Vestas WT modelat one end, and a slack bus generator at the other. The middle bus is where the fault isapplied. The system is shown in Figure 3.

Where Prate is the rated MW value; Qind and Qcap are the turbine reactive power inductive and capacitive lim-its.

*Vestas WTGs are not configured for terminal voltage control. Therefore the user should select the appropri-ate reactive power condition and configure the load flow case accordingly.

In PSS/E the value of ‘Zsource’ is calculated from the maximum short circuit current con-tribution (Ik”=1.05 p.u.). Recommended values of source resistance and reactance aregiven in Appendices.

The bus to which the wind turbine(s) is (are) connected should have the same level ofvoltage as the generator terminals, in fact this bus is the low voltage side of the 2-windingstur bine’s transformer. The turbine’s transformer is not included in the model and is left tothe user to implement in the simulation as a PSS/E standard 2 winding transformer formore details see section 6.2.

For aggregated WTGs, parameters 1, 2, 4, 5, 6 & 7 needs to be scaled to represent thedesired number N of aggregated units.

7 User related Sub-models of Vestas Wind Turbines

This section describes different sub models in the dynamic data file.

7.1 Reactive Power ControlThe turbine can operate within certain limits for active and reactive power. The limits areprimarily determined by the converter and the generator. There are two possible controlmodes:

Q-Control.

Power Factor Control.

The PSS/E user written model will independent of which of the modes that is selected, pri-oritize the active power higher than the reactive power. This means that the highest possi-

ble active power – which is the user-defined (requested) active power – will be supplied tothe grid even though it might compromise the control mode performance.

Active Power PriorityThe model implemented always gives highest priority to the active power. That means thatif both P and Q are outside the valid operating area, Q is limited in order to bring the tur-bine inside the safe operating area. This is illustrated in Figure 7 (A typical PQ chart forVestas turbines) where the references (P* and Q*) are both outside the chart. In this caseQ is limited in order to bring the turbines operating point inside the operating area again.

PF Control

When activated, the required Q will be calculated based on the P and the PF set point.Depending on the working point, whether it is a full or partial load operating point and alsowhether it is lead or lag, the PF set point is subject to possible minimum or maximum as

shown in Figure 11.

Changing Q and PF set point (Qset)Reactive power set point (Qset), defined in ‘GSVARS’ sub-routine. This set point is as-signed to VAR L+1 can be changed to desired value using ‘ALTR’ activity.

VARs Description

L Available real power, Pset

L+1 Q or PF set point, Qset

7.2 LVRT Control SettingsDuring low-voltage-ride-through (LVRT), Vestas turbines switch from power control to cur-rent control mode. The following settings can be changed by the user in order to carry ondifferent system studies.

Active current Priority As default, Vestas turbines are designed to maintain and control reactive current duringLVRT. However the user could also select the active current priority, If supplying activepower is required during LVRT.

The Active current priority setting can be enabled by changing CON J+7 of ’GSLVRT’ to1.0, and be disabled by changing CON J+7 to 0.0.

Q-offset SettingIn case the turbine reactive output is not zero at pre-fault condition, the Q-offset can beused to remove the step change when Vestas turbines switches between power controland current control.

The Q-offset setting can be enabled by changing CON J+31 of ’GSLVRT’ to 1.0, and be

disabled by changing CON J+31 to 0.0.

Asymmetrical fault

If asymmetrical fault study is required, asymmetrical fault settings should be enabled andthe user should provide negative sequence magnitude (U-) input in VAR L+12 of’GSLVRT’.

The asymmetrical fault setting can be enabled by changing CON J+32 of ’GSLVRT’ to 1.0,and be disabled by changing CON J+32 to 0.0.

7.3.2 LVRT Logic

As default, the Vestas GridStreamer TM wind turbines is a LVRT enabled turbine, and theVestas PSS/E model will represent this. The turbine is designed to stay connected on thegrid in case of a number of severe faults.

The LVRT option is affected by two user defined parameters (LVRT_flag and AGO_enable) as explained in Table 11.
