摘要
在剖析接地阻抗继电器零序电流补偿系数物理意义的基础上,深入研究了阻抗型补偿系数和电阻k R和电抗k X分别补偿系数的特点及两系数之间的区别;提出了两补偿系数之间的转换方法及转换条件;并结合工程实际,举例说明了圆特性和四边形特性接地阻抗继电器模拟试验的参数计算方法。
By analyzing the physical sense of earth-fault impedance relay's zero-sequence compensation factor, this paper researches impedance compensation factor and resistance kR and reactance kx , and distinguishes two factors. It also introduces the converting method and the converting condition of the two factors. Combined with the engineering practices, this paper introduces the method of calculating the parameter of circularity characteristic and quadrangle characteristic earth-fault impedance relay commissioning tests.
