1.2 Short-Circuit Calculation acc. IEC 60909 (VDE 0102)

ATPDesigner provides a short-circuit calculation based on but not identical to the European Standard EN 60909-0:2001 (IEC 60909-0:2001). The short-circuit calculation based on EN 60909-0:2001 implemented in ATPDesigner only respects a subset of the European Standard EN 60909-0:2001. Therefore the results of the short-circuit calculation based on EN 60909-0:2001 implemented in ATPDesigner may deviate from the results of the short-calculation which completely respects the standard EN 60909-0:2001.

Please NoteIt is recommended to study carefully the European Standard EN 60909-0:2001 (IEC 60909-0:2001) and this manual before starting to use the Short-Circuit Calculation based on VDE 0102 in ATPDesigner. This manual doesn't replace the complete information of the standard EN 60909-0:2001 (IEC 60909-0:2001).

Caution !!!The Short-Circuit Calculation based on VDE 0102 implemented in ATPDesigner shall be used only for educational purposes.

Figure 2: Settings Dialog IEC 60909 (VDE 0102)

Several settings have been added for existing network elements e.g. Electrical machine, etc.. Please read more details in the chapter VDE 0102 (IEC 60909).

2 Improvements

2.1 Probe

ATPDesigner now calculates not only the phase currents currents iABC(t) and phase-to-ground-voltages vABCG(t) but also

§ the apparent power S,§ the active power P,§ the reactive power Q,§ the power factor cos ϕ,§ the amount of the phase-to-ground voltages VABCG and§ the amount of the phase currents IABCG

using the MODELS of the ATP based on a Discrete Fourier Transformation.

2.2 Probe: Overcurrent Protection

A new setting IG> has been implemented to realize an Ground Overcurrent Protection element.

2.3 Circuit-Breaker and Switches

If a circuit-breaker or a switch had been opened during the network simulation e.g. by MODELS the circuit-breaker or switch will be drawn in red. In addition the opening/closing times will be now shown in the Messages Window.

Figure 5: Switch Opening by MODELS

In addition ATPDesigner displays the switching time of the breaker in a tooltip.

2.4 Short-Circuit Analysis (ATP Steady State)

ATPDesigner shows the flow direction of the active power P directly in the power network graphics using green arrows. The active power will be calculated based on the active power of each phase. Therefore the power flow direction can be used for symmetrical as well as for unsymmetrical network states.

Figure 7: Flow Direction for the Active Power P

2.5 Transformer

The neutral point connection will be now presented as a bitmap.

2.6 Load

the network element Load Impedance can be now set to a D-connection.

2.7 Short Circuit Analysis (Steady State Analysis)

A new right mouse button menu has been implemented, which will be displayed, if a Short Circuit Analysis has been successfully executed.

Results

2.8 Measurement Data Frames of a Probe

ATPDesigner also supports displaying the results of the short circuit analysis in Measurement Data Frames, which are assigned with each Probe. The Measurement Data Frame of a Probe is disabled as Default, must be enabled for each Probe.

The list blow shows the different contents of the Measurement Data Frames, which can be selected by the F-keys.

2.9 Circuit-Breaker and Measuring Locations

If a circuit-breaker with enabled measuring location will be deleted, now both the circuit-breaker and the measuring location will be deleted in one step. An warning will be displayed in the messages window.

2.10 Network Configuration

The name of a Switch or a Circuit-Breaker can be now displayed or not displayed in the power network graphics. As default, the name will be not displayed.

2.11 Edit Controls with integrated List Box

Some edit controls e.g. to define the nominal voltage of a Probe are now improved by a list box control.

2.12 3-Phase-Source

A new operation mode Pnom (Ip) = const. has been implemented. This source type is a current source but with active power P = const, which will be achieved by the iteration algorithm Phase Adjusting implemented in ATPDesigner. ATPDesigner measures teh phase-to-ground voltages at the infeed node of the source and recalculates the amount of the current source depending of the user specific P = const.

2.13 Phase Adjusting: Stop pressing ESC

The phase adjusting iteration can be now stopped pressing the ESC button.

3 Bug FixesThe bug fixes may be related to all former ATPDesigner releases.

3.1 Line, Cable, Connections

The snap point at the middle of the line, cable, connection was not recalculated if the shape has been changed. This bug is now fixed.

3.2 MODELS: Syntax Check

ATPDesigner now checks the syntax of the if - and for - conditions before executing MODELS.

3.3 MODELS: DFT Template

ATPDesigner calculates the voltages and currents based on the DFT (Discrete Fourier Transformation) now as r.m.s. values.

3.4 Network Infeed

ATPDesigner now processes now the short-circuit current Ik3" as well as the short circuit power Sk".

3.5 Single Circuit Lines

§ Dielectric Dissipation Factor tan(α)The former loss angle has been renamed to dielectric dissipation factor tan(α). The calculation of the resistances has been fixed. The edit control of the phase-to-phase dielectric dissipation factor tan(αPP) has been disabled in the corresponding settings dialog of the line. The default settings has been set to 0.0 for both settings phase-to-phase dielectric dissipation factor tan(αPP) and phase-to-ground dielectric dissipation factor tan(αPG).

4 New Examples (.NET – Files)After the ATPDesigner setup has been finalised, the user will find some .NET-files, which makes it more easy to start with ATPDesigner. In addition the user can study the features of ATPDesigner analysing these examples. The content of each .NET-file is explained in the chapter Examples and Data Cases in the help file.

§ New .NET-files are not available.
