多功能电力参数微机监控装置设计

Design of the Multifunctional Microcomputer Monitoring Device for Electric Parameters

针对我国大多数配电间的实际运行条件与管理水平 ,研究以单片机为基础的电力参数微机监控装置 ,讨论了该装置的硬件结构原理和软件设计思想。该装置能同时测量交流电压、交流电流、功率因数、有功功率、无功功率等各种参数 ,且具有负荷、功率因数自动控制、统计电压质量、缺相保护、报警及报表打印输出功能。一年多的运行结果表明 ,该装置性能稳定、工作可靠。

In the paper, according to the actural operating condition and management level of many distribution substations,the microcomputer monitoring device based on a single chip processor was studied. And its hardware and software structures were discussed. The device can not only be used to measure alternating voltage, current, power factor, active power and inactive power, but also provide many functions, such as power load and power factor control, voltage quality statistics, lost phase protection, and printing out. One years application showed that the device presents good performance and high reliability.
