摘要
介绍了竞争子网络的工作原理和结构 ,提出基于竞争子网络邻抑制作用的数字滤波法 ,并将该方法运用于局部放电在线监测系统的抑制通信干扰的滤波环节中。实践证明这种方法具有自适应性强、通信干扰抑制效果好、运算速度快等优点。
The principle and structure of the competition subnet are introduced. A digital filtering method based oncompetition subnet's lateral inhibition effect is proposed. The method is applied in the digital filtering part of on--site partialdischarge (PD) monitoring system for the purpose of eliminating communication interference. Practical results show that themethod has strong adaptability and good filtering effect. The calculation is fast too.
