摘　　要：利用ＰＲＯＮＹ算法对小电流接地系统的故障电流暂态过程进行了分析，并根据暂态电流中各分量的频率、阻尼、幅值和相位等参数与故障类型之间的关系，探讨了一种优于传统方式的小电流接地系统电网故障定位的新途径。Using Prony method, this paper analysis the fault currents of Peterson Coil Protected networks during transient process, and based on parameters of the frequency, damping, magnitude, phase of the components of fault currents and fault types, this paper presents a new way to solve the fault locating in Peterson Coil Protected networks which is better than those traditional methods.

关 键 词：PRONY算法 小电流接地电网 故障定位
