摘要
针对同杆并架多回线路零序互感对零序保护及接地距离保护整定计算影响进行了详尽分析,提出了利用软件、应用“测量法”的概念进行整定,保证保护的选择性,通过软件仿真验证了其正确性。
The impact of mutual inductor on setting computation of zero sequence protection and ground distance protection carried on parallel multi-circuit transmission lines are analyzed. A method of using software and applying the concept of measuring means is proposed. It assures the selectivity ofprotection. The software simulation proves that this method is correct.
