摘要(Abstract)：
以镇海电网的现状为出发点,分析了影响电网功率因数合格率的主要因素,并根据实际情况,提出了修改VQC定值、完善管理流程、进行变电站补偿电容器容量调整、加强指标管理等多项技术和管理措施。通过技术改进、流程管理、电网运行方式的综合调整,大大提高了镇海电网的功率因数合格率。
Starting with the present status of Zhenhai power grid, the paper analyzes main factors influencing power factor qualification rate of grid power; in addition, it puts forward a number of technical and management measures such as modifying VQC constant value, perfecting management process, adjusting capacity of compensating capacitor in the substation, strengthening index management, etc. Qualification rate of power factor of Zhenhai grid is greatly enhanced through technological improvement, process management and comprehensive adjustment of grid operation mode.
