Software Patches

Features and Improvements

  • Transient Stability: Created new ESST1A_GE model because PSLF handles input parameters related to the location of the PSS input and UEL input differently than PSSE.
  • Transient Stability: Added default columns for present MW and Mvar to Load Characteristic and Load Relay model case information displays.
  • Bug Fixes

    • File Formats: An error could occur if appending a case that contains existing interfaces with a PWB file that also contains interfaces.
    • Transient Stability: Fixed error in stabilizers PSSSB, PSS2A, and PSS2B when n=0. This now means the ramp tracking is completely bypassed. Previously setting n=0 was causing simulator to disable the stabilizer completely which was incorrect.
