Features and Improvements

  • Bus View and Substation View Onelines: Modified the option for showing field labels so that it shows the column heading text of the field because this is much shorter.
  • File Formats: Modified reading of the hdbexport CSV file to better handle records indices which are skipped.
  • File Formats: When reading an EPC file and writing a message regarding a bypassed branch record we include R, X, and B values in the log message.
  • Transient Stability: Modified showing of Results from RAM to better show results for multiple contingencies.
  • Transient Stability: Modified the reading/writing of the WT3G and WT4G models from a DYD file so it read the Khv and Iolim fields. These fields are not used by Simulator, but that are read gracefully and written back out as well.
  • Transient Stability: Modified the reading/writing of the WT3G and WT4G models from a DYD file so it read the Td field and uses it appropriately.
  • Transient Stability: Modified the reading/writing of the WT4E model from a DYD file so it reads the ImaxTD and Viqlim parameters. Previously these were hard-coded to 1.7 and 1.6 always.
  • Bug Fixes

    • Transient Stability: Modified reading the PTI DYR file so that it handles models written across multiple lines of a text file. Also modified so that we ignore an extra comma at the end of a DYR record.
    • Transient Stability: Fixed an error in the AC7B exciter model with an incorrect sign on the derivative feedback block.
