Features and Improvements

  • General: New distributed computation configuration command line tool has been added to aid in scripting the automatic configuration of multiple machines across a network.
  • Transient Stability: Added new CDC1T two-terminal DC line model. This is a stripped down version of the CDC4T model.
  • User Interface Dialogs: Added two new tabs on the Contour Options dialog. Contour Data Points shows the x,y location on the oneline of the object being contoured and the value of the field being countoured along with the color of the countoured value. Contour Pixels provides details about the pixel color and location in the contour.
  • Bug Fixes

    • File Formats: Fixed access violation that could occur when loading DYR file containing SVCs.
    • File Formats: Updated Areva contingency parser to handle injection groups (LDAREA). Previously they were unhandled, which resulted in them being incorrectly treated as line open contingencies (the default). This was causing an access violation when saving the contingency list to file.
    • Simulator Automation Server (SimAuto): Fixed RegSimAuto registration check so it no longer fails when checking to see if the registered SimAuto executable and the local executable are the same files.
    • Transient Stability: Fixed significant error in the loading of PSSE User Defined GENPTJ models. We were treating the Kis field as Ra.
    • User Interface Dialogs: Disable the Area/Zone/Owner filter option on the Area/Zone/Owner filter dialog and the Tielines between Areas case information display. The Area/Zone/Owner filter is not applied here.
    • User Interface Dialogs: Enabled Advanced Filtering for the Area and Zone case information displays on the Limit Monitoring Settings dialog.
    • User Interface Dialogs: Disabled the option to Use Area Zone Filters for case information displays that do not allow Area/Zone/Owner/Data Maintainer filtering. This option wasn't doing anything but this change makes it clearer that it is not applicable.
