换流变压器差动保护调试软件的开发与应用

针对换流变压器保护调试过程中存在的问题,通过对差动保护调试耗时长、效率低、精度差等原因进行具体分析,开发了一款“换流变压器差动保护测试电流计算软件”。应用结果表明:以软件算法代替人工计算,大大缩短了换流变压器保护调试时间和换流站大修时间,降低了劳动成本,提高了保护调试工作效率,可为全国所有直流换流站换流变压器保护调试提供参考。

Development and application of debugging software aboutdifferential protection of convertor transformer

Aiming at the problemexisting in the debugging process of convertor transformerprotection, by analyzing the factors of the long time debugging, low efficiency and poor precision of thedifferential protection, the calculation software of test current about differential protection of convertertransformer was developed. The application results show that the substitute of software algorithm forartificial calculation can greatly shorten the debugging time of the convertor transformer protection andthe overhaul time of the converter substation, reduce the labor cost and improve the efficiency of theprotection debugging, which provide some reference for convertor transformer protection of DCconverter substation .
