摘　　要：电力系统中投入的电容器容量过大将导致系统过补偿,功率因数反而会降低,且造成资源浪费,不经济。合理选择补偿电容器及运行方式,可以提高系统功率因数,节约企业运行成本。Excessive capacity of operating capacitors in power system will lead to overcompensation and power factor reduction,causing waste of resources.Appropriate selection of compensation capacitor and operation mode can improve power factor and save operation cost of enterprises.
