Microprocessor-based control for an ac-dc power conversion system with dc interrupter protection. Final report 82-9G2-INTER-R1, June 1, 1979-December 31, 1982.

摘要

The use of microprocessors in power converted controls is of interest, since they could potentially reduce system costs, increase system adaptability, and enhance system reliability where analog circuitry is conventionally used. This report discusses the techniques that were applied in designing a complete microprocessor-controlled ac/dc power conversion system, including thyristor-gating control and closed-loop regulation of system voltages. The project also served as a vehicle for further evaluation of a ringing-bypass valve dc interrupter that had been previously designed in work related to the ac/dc conversion system used here. The microprocessor control techniques described here are applicable to most energy conversion systems where a dc power source exchanges energy with an ac network via line-commutated converters. 4 refs., 33 figs.
