Bug Fixes

  • Transient Stability: When choose to "OPEN NEAR" or "OPEN FAR" TSContingencyElement on a transformer branch, the impedance was not be modelled correctly. This has been fixed.
  • Transient Stability: Modified reading of various transient stability ASCII text file formats to process the file looking for illegal characters such as NULL (#0) characters before reading them. These illegal characters are then ignores. This impacts ready the DYD, DYR, MCRE RWM, MTR_LD, GNET, BASEGEN, and IDV files. This had been done for nearly all other 3rd party text file formats, but had not been done for the various transient stability input files until now.
  • Transient Stability: The default setting for when to engage Fast Valving for the TGOV2 and TGOV3 models is now set to never ("MOD_FastValvingOption"="None").
