利用数字式保护测试仪进行数字化变电站调试

Digital Substation Debug Using Digital Relay Testing Instrument

通过无锡第1座数字化变电站——圆石变电站的保护调试,介绍了数字式测试仪的工作原理和用数字式保护测试仪进行保护调试的方法,对数字化变电站的发展应用有一定的参考意义。

Digital substation is a hot subject in these years.Electronic transformer is the main character of digital substation.As the output of electronic transformer is not analog signals but digital signals,the digital relay cannot be tested with conventional test method,and the digital relay testing instrument must be used.According to the testing of Yuanshi substation,the operating principle and debug method of digital testing instrument is introduced,which guides the development of digital substation.
