Software Patches

Features and Improvements

  • Case Information Displays: Added new summary information for the summation of Load Dist MW Max, Load Dist MW Min, Load Net MW, and Load New Mvar for the following aggregations: Bus, Area, Zone, Substation, Owner, InjectionGroup. Previously you could only get information about the Min/Max and Net values for loads by looking at individual load records or by creating your own calculated field.
  • Bug Fixes

    • Distributed Computation: Fixed an issue in distributed contingency analysis where contingency violation injection sensitivities may be dropped when the controlling Simulator program is running on a computer under high load.
    • Distributed Computation: Added the ability to gather worst overload data over all contingencies for all branches when running distributed contingency analysis. Previously this data was only available through non-distributed contingency analysis.
    • File Formats: Bug fix for RAW file reading. Angle value was not being set correctly for node data read from a "SUBSTATION NODE DATA" section.
    • Transient Stability: Modification to help with numerical integration of the INDMOT1P and INDMOT1P_PTR load models
