Field Test of 70MW Class Superconducting Generator in The Mode of Synchronous Condenser

Abstract

In order to study the basic performance of the superconducting generator in the actual electric power system, the quick response excitation type generator was connected to 77kV commercial power grid of the KANSAI Electric Power Co., Inc. In the test, the model machine was operated as a rotary condenser supplying about leading 40MV ar to the electric power system. In the tests, the model machine operated stably. The results show that the superconductig generator has effects for stabilizing voltage fluctuations of electric power system and also for reducing shunt reactor.
