摘要
在辨别电网故障时各类事件发生的先后顺序中,SOE记录具有重要意义。该文对目前采用的遥信去抖方法进行分析,指出不同方法的特点。构建测试系统环境,在不同遥信去抖方法下,对SOE结果进行对比统计和分析。最后建议能够统一遥信去抖设计方法,保证SOE记录的精确性。
To distinguish the sequence of events during power failure, we need SOE records greatly. This paper analyses the methods of subtractive dithering signals, and points out characters of every method. We set up a testing environment, every method would be tested here. Finally, we bring forward one subtractive dithering method for signals measurement, to ensure the accuracy of SOE records.
