10kV并联电容器组的故障分析及应对措施

Fault Analysis and Reply Measure for 10kV Shunt Capacitor Bank

电力电容器作为一种静止的无功补偿设备,它的主要作用是向电力系统提供无功功率,提高功率因数。并联电容器无功补偿是电力系统中优先采用的无功补偿方式,以减少输电线路输送电流,起到减少线路能量损耗和压降,改善电能质量和提高设备利用率的重要作用。其安全性和可靠性,对于电网的安全经济运行具有十分重要的意义。本文立足于东莞供电局并联电容器运行现状及存在的各种问题,结合多年来的运行经验,从多方面进行分析,并提出相关的应对措施,以加强东莞电网无功系统的安全性及可靠性。

Electrical capacitor is a device as static reactive power compensation. It is mainly used to supply reactive power into the electrical system and to increase the power factor. Reactive power compensation of shunt capacitor is a first adoptive mode in power system, to reduce the transmission current, power loss and voltage drop on transmission line, to improve quality of electrical energy, and to increase use factor of equipments, it is taken important effect. Its security and reliability is very important sense for safety economical operating in power grid. Based on shunt capacitor operating status and existent questions in Dongguan supply bureau, and combine operating experience in many years, analysis and reply measure are advanced in this paper, to enhance security and reliability of reactive power system in Dongguan power grid.
