Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): The DetermineBranchesThatCreateIslands script command will now allow you to enter a blank for the filename. If the filename is blank, the selected field will be set for lines that create islands regardless of how you have that option set.
  • Contingency Analysis Tool: When saving the auto insert contingency options to an auxiliary file, any advanced filters used in the settings will also be saved to the aux file.
  • Simulator Automation Server (SimAuto): New OpenCaseType(FileName, FileType, Options) function. This function behaves the same way that the OpenCase script command works with FileType and Options being the same as those specified with the script command. The Options parameter is optional.

    • Bug Fixes

    • Case Information Displays: When editing a cell in any table, the cursor was not always appearing. This had been fixed.
    • Contingency Analysis: The status messages when contingencies are running will now show the number of contingency that is being processed based on all contingencies that are not set to Skip rather than all contingencies.
    • Contingency Analysis: The auto insert contingency options were not being correctly loaded from an auxiliary file. This has been fixed.
    • General: Modified InterfaceElement objects so that you can use the "Selected" field. This allows them to be used by AUX scripting.
    • Transient Stability: Modified when writing out a DYD file so that if the "mvabase" or "mwcap" values are zero then we just omit them from the output DYD file.
    • Transient Stability: For exciter model IEE5TA, when Trh was zero, the value for Vref was not initialized correctly. This has been fixed.
    • Transient Stability: Fixed issue with response of governor model GGOV3.
    • Transient Stability: Fixed a bug that would not correctly total the amount of generation or load that trips during a contingency and is not tripped due to a specific contingency action.
    • Transient Stability: Modified Generic Limit Monitors options to make it clearer that they are related to generator SPEED and not the bus frequency.
