超高压带串补线路的继电保护现场暂态测试系统

On Site Transient Testing System of Relay Protection for UHV Power Line with Series Compensation

为了检验应用于串联补偿系统的保护装置动作是否正确,运用加拿大RTDS公司生产的RTDS(实时数字彷真机)等设备构建的一套波形回放系统,对加装串联补偿电容后的500 kV交流线路及邻近线路的保护装置进行现场暂态测试。试验结果表明:保护装置能正确反应所设暂态故障。

This paper introduces on site transient tests of relay protection on 500 kV ac line with series compensation by a waveform playback system composed of RTDS （Real Time Digital Simulator） of the Manitoba HVDC Research Center and other apparatus. The purpose of the test was to examine the relay behaviors when series compensation is inserted in the UHV ac line. It is proved the relay protector can response to transient faults correctly.
