摘要

在高压变电站中，放置在开关站和控制室内的二次设备对开关操作引起的瞬态电磁干扰非常敏感。为了更好地评价瞬变电磁环境，指导二次设备抗扰度设计，有必要对这些瞬变电磁干扰进行测量和分析。当三个新的500千伏变电站通电时，测量和记录了许多瞬态电磁干扰。基于FFT，开发了一个分析程序，用于分析扰动的特性。对研究结果进行了总结。并与IEC61000-4系列标准进行了比较，提出了建议。

Measurement and analysis of switching transients in 500 kV substations

In high voltage substations, secondary equipment placed in the switchyard and inside the control house can be highly sensitive to transient electromagnetic disturbances due to switching operations. In order to evaluate transient electromagnetic environments (EME) and provide guidance for better immunity design of secondary equipment, it is necessary to measure and analyze these transient electromagnetic disturbances. While three new 500 kV substations were powered on, many transient electromagnetic disturbances were measured and recorded. Based on the FFT, an analysis program was developed and used to analyze characteristics of the disturbances. The results are summarized. Comparisons with IEC61000-4 series standards are made and recommendations are given.
