Bug Fixes

  • Transient Stability: Modified documentation of Vramp and Cramp parameters of the CDC4 and CDC6 type DC Line models to reflect that they are in the units of pu/sec.
  • Transient Stability: When restarting a DC line in transient stability after inverter bypassing, the units on Vramp and Cramp were not being treated properly and the DC line would restart at an extremely slow manner which was not correctly. This has been fixed. Note: the restart after rectifier blocking was correct. Now both Vramp and Cramp ramping for both inverter bypass and rectifier blocking is correct.
