Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): Updated the Move script command to accept labels to specify the branch and also accept a bus label instead of a bus number for the destination
  • File Formats: The Limit Monitoring option for "Do not monitor radial lines and buses" is no automatically reset to unchecked when loading a new RAW or EPC file. Previously it would remain at whatever setting it had before opening the RAW or EPC file.
  • File Formats: In the previous patch, features were added when loading a RAW file that were locating incorrect treatment in RAW file solutions if FixedNumBus with a mixture of Connected and Disconnected substation node statuses. This patch introduces features to automatically determine switching devices that could be closed to match the incorrect RAW file solution and prompt the user asking them if they would like us to close these switching devices.
  • Oneline Diagrams: Added Region Display Styles for creating automated oneline displays from geographic Region objects.
  • Transient Stability: When a vertical axis is set to ScaleMinAuto and ScaleMaxAuto the axis extremes are calculated automatically, however PowerWorld has always internally ensured that the range at least shows a variation in the 5th significant digit. A new option has been added to allow the user to specify a ScaleAutoRangeMin. This will ensure that the auto extremes calculated are enforce that (AutoMax - AutoMin) >= ScaleAutoRangeMin. If the range is less than this then the new range will be set to the average of the AutoMax and AutoMin plus/minus the ScaleAutoRangeMin/2.
    NewAutoMax = (AutoMax + AutoMin)/2 + ScaleAutoRangeMin/2
    NewAutoMin = (AutoMax + AutoMin)/2 - ScaleAutoRangeMin/2
  • Transient Stability: When ScaleMinAuto and ScaleMaxAuto are both set to YES and the user sets a value for ScaleInc, modified so that the maximum value used for an increment will be (Max-Min)/2 so at a minimum 3 points will be labels on the vertical axis. This prevents situations such as ScaleInc being set to 0.05 when the automatically determine Max is 1.02 and Min is 1.01 which would create a Y-axis without any scale because the increment was too big.
  • Bug Fixes

    • Oneline Diagrams: The local menu when right-clicking on a branch display object on a oneline shows the From and To bus numbers listed at the top of the menu. The "To:" was not propertly showing the To bus but was instead just repeating the From bus. This has been fixed.
