电磁骚扰信号的基本分析

Basic Analysis of Electromagnetic Disturbance

文中分析了电感电路和变电站开关操作产生的两类电磁骚扰,主要对数据进行初步分析,包括开关断开的瞬间产生的高频电压,时域分析(上升时间、下降时间、持续时间、峰峰值、能量谱、极性特征等)和频域分析(频带范围、主频分布),得到了初步统计结果。

According to the electromagnetic disturbance in inductance circuit and substation switching operation, this paper analyzes the basic data, including the high-frequency voltage of switch disconnec- tion, time-domain analysis （rise time, drop time, duration, peak value, energy spectrum, polarity, etc. ）and frequency-domain analysis （bandwidth, dominant frequency distribution）. At last, the paper comes to a statistical conclusion.
