A detailed digital model for the actual control system of the Pacific Intertie HVDC scheme is presented. The scheme is operated as multi-terminal bipole HVDC with four terminals in parallel. Each pole comprises two separately located converter station with independent converter controls at each end of the transmission line. The control model includes bipole, pole, station and converter control systems. Special control techniques for providing safe and stable operation of the parallel converters are described. The techniques also result in fast recovery of the HVDC transmission scheme following severe ac and dc system disturbances. Verification of the completeness and accuracy of the model are made using field tests made on the actual HVDC scheme.
