【摘要】 本文针对串联补偿线路接地距离保护,提出了一种新的电抗补偿系数方法。该方法原理简单、易于实现,完全消除了负荷电流、系统运行方式及补偿度的影响,能够准确测量出串联补偿线路的故障阻抗。经数字仿真计算,其结果是令人满意的。更多还原

【Abstract】 In order to improve measuring accuracy of the earth-fault distance protection of series compensated line a new method which employs the reactive compensation factor is presented in this paper. The method is simple in principle, easy in application, and fully immune from load flow, operation conditions of power system and compensation degree. The computer simulation shows that the results are satisfactory.更多还原
