摘要
Abstract
In the field of distribution automation system,the feeder terminal unit (FTU) is always applied to acquire signals of distribution networks,and to monitor distribution networks and control equipment.However,due to the existence of sensors,sampling circuit or outside interruptions,errors are inevitably introduced into sampling values when acquiring voltage and current,thus causing the acquired signals inaccurate and influencing the accuracy of measurements of distribution network parameters.Residual DC is one of introduced errors which cant be ignored.In this paper,a residual DC filter algorithm in AC sampling based on FTU is proposed.This algorithm is able to filter out the residual DC from acquired instantaneous sampling values,making data more precise and ensuring measurements of distribution network parameters more accurate.MATLAB software was applied to simulate this algorithm and the simu lation results showed a good effect of filtering out residual DC from AC sampling values,which is of strong practical Value.关键词
