摘要
针对局部放电对变压器绝缘性能影响较大的问题,本文设计了一种基于DSP的大型变压器局部放电在线检测电路,结合小波变换对信号进行消噪、提取,并对该方法进行了仿真。仿真结果证实,通过该方法可以实时的处理变压器中发生的局部放电。
This paper presents an online system monitoring partial discharge （PD） of large power transformers based on digital signal processing. This system will aid in the automatic detection for internal incipient faults in the transformers by employing method with Electrical Research Association （ERA） . Furthermore, the system can provide information to predict failures ahead of time so that the necessary corrective actions are taken to prevent outages and reduce down times.
