Real-time Calculation on Three-phase Line Loss of Power Distribution Network Based on Characteristic Measurement
摘要
Abstract
In allusion to the problem of low calculation precision of traditional calculation method for line loss of the power distribution network,this paper presents a new kind of real-time calculation method for three-phase line loss based on characteristic measurement.This method firstly computes three-phase line loss of the power distribution network according to basic principle of loop current method and proves that the loop current method is also suitable for the power distribution network with distributed generation (DG).Then,it uses intelligent metering terminal to measure characteristic quantity of changes of line loss and takes obtained characteristic quantity as input data for real-time calculation on line loss.This realtime calculation method for three-phase line loss based on characteristic quantity was applied in calculating line loss of Dongguan power distribution network with DG and was compared with equivalent resistance method.Comparison result indicates that accuracy of the former method is comparatively higher.关键词
