摘要
针对继电保护装置的采样零漂问题,首先对常规保护装置中的采样回路架构做了简要介绍,其次具体说明了采样零漂问题的产生和影响,最后提出了一些可以降低采样零漂的系统性软硬件设计方法。
In order to solve the problem of sampling zero drift in relay protection devices,this paper first briefly introduces the sampling loop architecture in conventional protection devices,then specifies the occurrence and impact of sampling zero drift,and finally proposes some systematic design methods that can reduce sampling zero drift.This paper has certain reference significance for the treatment of sampling zero drift problem and the design of sampling loops in this industry and other industrial devices.
