LABORATORY SCALE TESTBED BY AN ENGINE GENERATOR TO DEMONSTRATE FREQUENCY REGULATION

Abstract

A laboratory scale testbed to demonstrate frequency regulation has been established by a reciprocating engine generator with a flywheel. The flywheel is connected coaxially to the shaft of the engine generator through the powder clutch, because it is supposed that direct connection makes starting of the engine difficult. By connecting the flywheel, both the steady state power/frequency characteristic and the per unit inertia constant of the testbed are in the range of typical Japanese power system, and frequency fluctuation in steady state is decreased to tolerable level for the frequency measurement by developed control boards.
