In this paper

a kind of PC cluster-based parallel reactive power optimization system is proposed

which using parallel computing features quickly and efficiently solve reactive power optimization issue of the system.The C / S structure is used to install multiple clients into multiple computers and perform independent reactive power optimization computation.The server is responsible for parameter setting

calculation control and

according to the client computing capacity

reasonably distribute computation amount.The application in certain regional power grid is shown that the system improves effectively quality of the reactive power optimization and reduces greatly the computation time.
