Features and Improvements

  • Transient Stability: Added the option to Auto Insert Loads (only opening loads) Transient Contingencies in the Transient Stability tool.
  • Transient Stability: When selecting a Transient Contingency to Skip the entire row fields will grays out. This will help the user visually identify the skipped contingencies.
  • Bug Fixes

    • File Formats: PSSE RAW file generator records will be written out with WMOD = 1 when the FuelType =SUN (Solar) OR Unit Type = PV (Photovoltaic) within Simulator
    • Transient Stability: Modified the CMLD and CMLPDW model so that if a loading factor for a motor is set as 0.0, then we simply interpret as 1.0 instead. 0.0 causes divide by zero errors which don't make sense.
    • Transient Stability: Fixed a bug when Calculating Effective Impedance from Sequence Networks in the transient stability event for buses and branches. The issue is when the Ymatrix created with the sequence data is singular then it was creating an infinite impedance causing the simulation to stop. This has been fixed.
    • Transient Stability: Fixed a bug with SimAuto function TSGetContingencyResults. If the case was storing the results into Hard Drive the function wasn't returning any results. That problem is fixed and now it will return the requested results.
