低压配电网三相不平衡监测系统的设计与调试运行

Design and Commissioning of Three-phase Unbalance Monitoring System for Low Voltage Distribution Network

本文主要探究了三相不平衡监测系统的设计内容与调试效果。该系统的硬件部分主要由信号调理电路、ADS8364数模转换器、EM310通信装置等组成。三相电压和三相电流经调理电路后转化为ADS8364可识别的电压信号。经过数据处理后利用EM310通信模块将结果发送至数据中心,在显示器上呈现出来。本文在实验室环境下进行了10 kV配电网三相不平衡监测系统的调试运行,结果表明该系统能准确反映电力系统中三相不平衡情况,达到了设计预期。

This paper mainly explores the design content and debugging effect of three-phase unbalance monitoring system.The hardware part of the system is mainly composed of signal conditioning circuit,ADS8364 digital to analog converter,EM310 communication device and so on.The three-phase voltage and three-phase current are converted into a voltage signal recognized by the ADS8364 after the conditioning circuit.After data processing,the EM310 communication module sends the results to the data center and presents them on the display.In this paper,the three-phase unbalance monitoring system of 10 kV distribution network is debugging and running in the laboratory environment.The results show that the system can accurately reflect the three-phase unbalance in the power system and meet the design expectation.
