Features and Improvements

  • Transient Stability: Added WTGT_B mechanical model for a type 4 wind turbine.
  • Bug Fixes

    • Case Information Displays: Fixed error in calculating the amps of a load when the load is disconnected.
    • Transient Stability: When an IEEEG1 or CRCMGV were configured with the low pressure generator online AND the high pressure generator off-line, this resulted in an access violation. The governor model is assigned to the high-pressure generator which is off-line in this situation and was causing bad behavior. For now this has been fixed by ignoring the governor and thus the low pressure genenerator will be simulated without a governor.
    • Transient Stability: Added storage of the option to Include Remedial Actions in Transient Analysis to PWB files which will also allow this option to be included with distributed computing. Remedial actions had not been included with the distributed computing runs but this has been fixed.
