摘要: 以湖北电网500 kV变电站低压侧无功补偿装置为研究对象,统计分析了近年来湖北电网无功补偿装置的运行情况,总结出目前无功补偿装置的常见问题及易发故障。分析结果发现,目前湖北电网投运的无功补偿装置存在容量、额定电流、额定电压选用标准不统一,无功补偿装置存在易发热、鼓肚及渗油等管理与运行上的缺陷。针对上述问题,提出了防范无功补偿装置故障的措施与建议,以保障电力设备安全、可靠和经济运行。

Abstract: The low-voltage side reactive power compensation devices of the 500 kV substations in Hubei power grid were studied and a statistic analysis was made on the common problems and faults occurred in recent years. The analytical results show that the reactive power compensation devices that has been put into operation in Hubei power grid have such management and operative problems as divided standards for selecting capacity, rated current and rated voltage, being prone to heating, bulging and oil leakage. Some measures and recommendations were proposed for preventing the faults of reactive power compensation devices.

Key words: power grid, substation, reactive power compensation device, operation analysis, fault
