Features and Improvements

  • Transient Stability: Added the ability to read and write ESST5C model to a dyd file.
  • Transient Stability: Added the ability to read and write ESST6C model to a dyd file.
  • Transient Stability: Added stator frequency dependence on the CIM5_PTR model
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): In the SendToExcel script command the ClearExisting parameter was not being read correctly if enclosed in double quotes. This has been fixed.
    • Contingency Analysis: When using transient stability models with power flow contingency analysis no changes should be attempted if the device or the device's bus is disconnected. Not checking the bus connection status could cause excessive POSTCHECK loops. This has been fixed.
