智能电子设备在变电站综合自动化中的应用

Application of Intelligent Electronic Device in Substation Automation

结合实际工程,针对智能电子设备(IED)在变电站综合自动化的初步实现,提出了智能控制的需求及智能控制的方案,分析了智能控制的具体实现及可靠性问题。介绍了智能电子单元的其他功能,即断路器的机械操动系统的检测;对开关设备内关键部位的温升进行在线持续监测及对设备周围温度和凝露的在线检测。

For the realization of IED in substation automation,firstly,the requirements and scheme of intelligent control are introduced,and then the implement and credibility of intelligent control with the practical project are ananlyzed. Subsequently,some other important functions of IED are introduced,including the detection of mechanical operation system,on-line continuous detection of temperature rising of important parts in switch and temperature and condense around equipment.
