Multimicrocomputer-based controller for 12 MW GTO power conditioning systems

A multimicrocomputer controller was fabricated for a 12 MW power conditioning system (PCS). The configuration of the PCS, which consists of a 12 MW GTO (gate-turn-off) inverter, series reactors, output transformers, AC circuit breakers, and a PCS controller, is described. The functions of the controller are outlined. Results of performance tests that were conducted on a 20 kW PCS model and on the 12 MW PCS are reported, reflecting the excellent performance of the controller.<
