摘　　要：由于线变组接线简单,投资少,在石油化工及煤化工等工业中得到了广泛应用。从工业需求、设计要求等方面分析了利用AREVA MiCOM P521装置实现线变组差动的原理,得出了相关结论,并对同行业用户的实例进行了分析。Due to the simple wiring and low cost, the line-transformer group is widely used in petrochemical industries and coal chemical industries. The theory and application of the line-transformer group protection based on MiCOM P521 protection of AREVA were analyzed. The relevant conclusions based on the analysis were obtained. Its application in petrochemical industries was discussed.
