Features and Improvements

  • Transient Stability: Added the ability to read the user defined model WTDTAU1 from a DYR file and treat it as the WTDTA1 model
  • Bug Fixes

    • Contingency Analysis: Modified the Branch Field for AggrMVAOverload. Previously it was taking the AggrPercentOverload field and multiplying by the present MVA limit of the branch. The problem with this was that the contingency MVA limit may be different than the normal MVA limit. This has been fixed so that it will use the limit that was used in the contingency analysis results.
    • Sensitivity Calculations: When calculating LCDFs through the LODF sensitivity dialog, the signs of the LCDFs should change if selecting the nearbus of the closed line as the actual to bus of the line. The signs of the LCDFs were the same regardless of which nearbus was selected. This has been fixed.
