摘要
在分析宽频带局部放电在线监测系统中的周期性干扰特征的基础上 ,从解决自适应直接陷波滤波器被淘汰的原因着手 ,提出了一种适用于宽频带局部放电在线监测中抑制周期性干扰的直接陷波滤波方法。文中详述了直接陷波滤波器的基本原理及设计方法。通过模拟仿真和实验证明该滤波器能有效的抑制局部放电在线监测中的周期性干扰 。
In the paper,we analyze periodic interference in PD wide bandwidth monitoring on line and its charac- teristics.A suitable method of rejecting periodic interference in PD wide bandwidth monitoring on line through direct wave trap filteris proposed.The principle and design methods are discussed.Experimental results are giv- en.The results prove the method is novel and effective.In filter process it is possible to compress the data and to extract the characteristics value.
