直流系统接地探测的微机集散监测系统的开发

Development of Distributed Computer Monitor System on Detecting the Gronnd Point of DC System

文中介绍了根据低频信号变频探测原理和计算机控制技术研制开发的直流系统接地计算机集散监测系统。该系统的开发解决了我国电力系统中直流系统接地点探测长期不能自动监测的难题。

In this paper, we introduced a distributed computer monitor system of DC system. In the system,we adopt computer control techology and design is based on the principle of detecting the ground point with low frequency electric current signal changing its fnequeney. This design solved the problem that ground point of DC system can't be automatically detected in our country.
