高速铁路差动保护调试升流装置研究

Researches of High Current Generator for Differential Protection Commissioning of High Speed Railway

研究采用高精度相位伏安表与二次升流技术相结合的调试装置进行继电保护装置电流数据、变压器差动保护各向量、比率差动功能测试;通过工程应用案例,证明应用差动保护升流装置后,继电保护装置可全面检验差动保护功能,结果显示准确。

The high precision phase volt-ampere meter and technology of current rising at secondary side combined commissioning device is studied and adopted for testing the current data of relay protection device, various differential protection vectors and ratio differential function for transformer differential protection; on the basis of engineering application cases, it is verified that the relay protection device is able to fully inspect the differential protection functions with correct display of results, after application of high current generator for differential protection.
