Model development of an actual HVDC control for the RTDS/sup TM/ simulator

The development of detailed models of the Manitoba Hydro HVDC Bipole I and Bipole II controls has been undertaken to allow rapid evaluation of contemplated changes to the controls and to allow evaluation of potential adverse interaction with physical controls on remote power system components. Ideally, a duplicate set of HVDC controls would be connected to a real time simulator to study these problems. In this case however, duplicate controls were not a practical possibility and detailed software models for the RTDS/sup TM/ have been developed instead. To implement the controls on the RTDS/sup TM/, software models are first written in FORTRAN and tested using PSCAD/EMTDC. The models are then converted into functional blocks for integration into the RTDS/sup TM/ Controls Compiler. Final evaluation and debugging of the control blocks is done for each subsystem and a reduced HVDC model. After satisfactory subsystem response is achieved, the overall system response is compared with EMTDC models.
