Prony 方法是一种估计信号中存在的模态分量的技术。每个模态分量由四个参数频率、幅度、相位和阻尼定义。该方法用于分析 Petersen 线圈保护的 20 kV 网络中的接地故障电流。给出了Prony参数随某些电力系统特性（母线与故障点之间的距离、故障电阻和全网电容电流）的变化。结果表明，与故障电流瞬变相关的一些 Prony 参数可能有助于确定发生的故障类型及其发生位置。 >
Prony's method is a technique for estimating the modal components present in a signal. Every modal component is defined by four parameters frequency, magnitude, phase, and damping. This method is used to analyse earth fault currents in Petersen-coil-protected 20 kV networks. The variations of Prony's parameters in terms of some of the power systems characteristics (distance between the busbar and the fault, fault resistance and capacitive current of the whole network) are presented. It is shown that some of the Prony's parameters relating to the fault current transient may be useful to determine what kind of fault occurred, and where it occurred. >
