2021.2 Software Release


Components with runtime-tunable properties

Windowed mode for HIL SCADA sub-panels

Setting AO/DO signals in Schematic Editor

IGBT leg with switch-level oversampling

SEL-751 relay digital twin model

DER models with VoltVAr and HzWatt grid support

Components with runtime-tunable properties

Test faster, compile less.

paragraph

 

  • Up until now many parameters of Signal Processing components were not tunable during runtime. This required model compilation for every parameter change.
  • From now on, you can change the parameters of Signal Processing components during simulation. Some of the parameters you can change are:
    • Value of the constant component
    • Amplitude and frequency of the sinusoidal, triangular, and wave source
    • Filter parameters
    • Etc.
  • Your manual and automatic tests now take much less time and run more fluently

 

 

Windowed mode for HIL SCADA sub-panels

HIL SCADA is video-wall ready.

paragraph

 

  • Support for working with a separate windows in a single SCADA panel.
  • Sub-panels can now work in Windowed and Embedded modes (right click -> Switch to Windowed mode).
  • If Windowed mode is selected, double clicking puts the Sub-panel canvas in a separate window.
  • Sub-panels in windowed mode can be set to full screen mode.
  • In Embedded mode, the Sub-panel keeps its usual behavior.
  • Saving a panel saves the complete panel layout (windows sizing and positioning).

See more of what’s important.

paragraph

 

  • Especially useful when working with complex Microgrid models.
  • Fast and easy navigation to commands and readings inside different sub-panels.
  • Improved situational awareness on multiple screen setups (i.e. video walls).

 

 

Setting AO/DO signals in Schematic Editor

Improved model version control for AO/DO signal setup.

paragraph

 

  • The AO/DO signal settings can now be done in the schematic file.
  • Better model version control by eliminating the need for setup in HIL SCADA or in standalone tests.
  • Packaging power stage models for C-HIL in library components without manually scaling adjustments in SCADA.
  • In larger systems, where multiple controllers and Multi HIL setup are included, moving controller to another HIL is easier.
  • Easier C-HIL model expansion from unit to system level.

 

 

IGBT leg with switch-level GDS oversampling

paragraph

Improved precision in high frequency switching applications.

paragraph

 

  • When switch-level oversampling for IGBT leg component is enabled, compensation is done to every switch independently, contrary to global GDS oversampling where compensation is done on global level
  • This component is useful in Dual-Active Bridge (DAB) and resonant converter applications since it grants much more precise simulation results on higher switching frequencies

 

 

SEL-751 high-fidelity model

paragraph

Deploy ANSI protection functions in your microgrid and converter models

paragraph

 

  • High-fidelity model of feeder protection relay.
  • Configurable with SEL settings and logic files.
  • Support for following protection functions:
    • Instantaneous/Definite-Time Overcurrent functions (phase, neutral, residual, and negative-sequence protection): ANSI 50P, 50N, 50G, 50Q
    • Time Overcurrent functions (phase, maximum phase, residual, neutral and negative sequence protection): ANSI 51P, 51PP, 51G, 51N, 51Q
    • Undervoltage functions (phase, and phase to phase protection): ANSI 27P, 27PP
    • Overvoltage functions (phase, phase to phase, residual, and negative-sequence protection): ANSI 59P, 59PP, 59G, 59Q

 

 

DER Models with VoltVAr, HzWatt and VoltWatt Grid Support

paragraph

More grid support functions for generic DER components

paragraph

 

  • Support VoltVAr, HzWatt, and VoltWatt grid codes in generic DER components
  • Grid voltage triggers the VoltVAr and VoltWatt
  • Grid frequency triggers the HzWatt
  • Customize VoltVAr, HzWatt, and VoltWatt requirements

VoltVAr functionality.

paragraph

 

  • Enabled from HIL SCADA
  • The reactive power injection depends on the voltage on the terminal of the DER

HzWatt functionality.

paragraph

 

  • Enabled from HIL SCADA
  • The active power injection depends on the frequency on the terminal of the DER
  • If the frequency is out of range the DER will stop running

VoltWatt functionality.

paragraph

 

  • Enabled from HIL SCADA
  • The active power injection depends on the voltage on the terminal of the DER
