随着串联电容器补偿技术在中国电网的广泛应用,迫切要求对影响其运行可靠性的快速暂态过程进行研究,以采取必要的防范措施。为了适应对串补装置中多导体系统应用部分单元等效电路（partial element equivalent circuit,PEEC）方法建模的要求,对复杂多导体系统的部分电感矩阵提取方法进行了研究。构建了一个能够描述任意空间导体元段对位置关系的完备集合,针对集合中每一种位置关系元素采用特定的解析公式,设计出一种可用于复杂多导体系统部分电感工程计算的通用方法。实验表明,所编制的计算程序（LPCal）的计算精度可以满足快速暂态过电压工程计算的要求。

With the wide application of series capacitor compensation（SC） technique to the power grid of China,it becomes necessary and urgent to study the fast transient process which affects the operational reliability of the SC equipment,and further to take necessarily preventive measures.The extraction method of partial inductance matrix was studied in order to meet the partial element equivalent circuit（PEEC） modeling demand of multi-conductors system in compensation equipment.The complete set describing any spatial relationship of segment pairs was constructed;a universal engineering calculation method was designed for the partial inductance of complicated multi-conductor system by assigning specific analytical formula to each element in set.Experiments show that the accuracy of calculation results by the program（LPCal） proposed in this paper can meet the requirement of engineering calculation of fast transient overvoltage.
