摘要

基于电磁暂态仿真程序ATP-EMTP

以某110kV变电站为例建立仿真计算模型

本文分析了该变电站35kV侧母线PT谐振特性及其激发因素。通过把傅立叶变换和小波分析相结合实现了对中性点不接地系统谐振母线过电压信号的检测。仿真模型和计算分析结果对于现行变电站、新建变电站及在线检测系统设计中谐振过电压的抑制和检测问题提供了参考。

Abstract

TP-EMTP simulation program is applied to establish the simulation model for one 110 kV substation.Based on this simulation model

the substation ferroresonance over-voltage resulting from the electromagnetic potential transformer（PT） of the 35kV bus bar is studied deeply.Moreover

FFT combining wavelet transform is applied to detect the ferroresonance signal for this Neutral-isolated system.The simulation model and simulation results can be referred

when suppressing ferroresonance over-voltage and detecting it in substations in service and new substation’s design.
