多通道实时电能质量监测系统

Multi-channel and Real-time Power Quality Monitoring System

当前,电力部门对多通道、高精度、实时性的电能质量监测系统具有迫切的使用需求。文中根据IEC及国家标准规定的电能质量参数计算方法,设计了以电压/电流测量模块为核心的多通道电能质量监测系统,实现对我国电网主要性能指标的实时监测分析与记录。该系统对信号的采集和处理采用了模块化的设计思想,可以根据应用的工业场景进行适配性的多路电压与电流的分析检测。

Nowadays, a urgent need for multi-channel, high performance and real-time power quality monitoring system is raised for the state grid operator. This paper analysed the IEC standard and the Chinese national standard on the methods to calcu- late power quality parameters, and designd a multi-channel power quality monitoring system based on a measure and process module for voltage or current. The system is able to conduct real-time analysis and recording of the key quality indicators within the state grid system. Because the signal detecting and processing circuits are designed in a modularized way, the system is highly flexible and scalable in the monitoring of multi-channel voltage and current, according to different industry scenarios.
