System and method employing a digital computer with improved programmed operation for automatically synchronizing a gas turbine or other electric power plant generator with a power system

摘要: A gas turbine power plant is provided with an industrial which drives a rotating brushless exciter generator coupled to system through breaker. One or more of the turbine-generator plants are operated by hybrid digital computer control during sequenced startup, synchronizing, load and shutdown operations. The program for external analog circuitry operate in multiple loop arrangement. Automatic synchronization achieved subsystem includes programmed phase detection circuitry. An automatic divided into rough speed voltage matching, fine matching breaker closure subprograms.
