Synchronous Condensing Using the Generator of Peak Load Plant

Abstract

This paper will describe how a generator of a peak load turbine, when operated as a synchronous condenser, can help improve electrical system power factor and therefore help maintain reactive power balances between sources of generation and demand points. It is particularly appropriate to use peak load plant with either industrial or aero-derivative gas turbines for synchronous condensing. By using a clutch to disconnect the turbine from the generator, losses from the turbine are avoided enabling more efficient synchronous condensing operation. Details of specific clutch designs for turbine generator synchronous condenser applications and experience at various B.C. Hydro installations are provided.
