随着智能变电站的改造和建设,对变电站一次设备在线监测的需求不断增加,对监测技术的要求也不断提高.在实际应用中,同一个变电站中多种一次设备的多个电气参数及运行状态需要实时传入监控中心.而目前各厂商生产的监测IED相对独立,数据采集及通信接口种类规格不一,使得监测IED的安装运行变得复杂.研究并设计了一种基于嵌入式可用于监测多种一次设备参数的综合监测IED,嵌入了IEC61850标准协议.试验及运行结果表明,该综合IED在实际应用中安装简单,运行可靠,很好地降低了施工成本,节省了安装空间,提高了监测系统的稳定性.%With the reform and construction of smart substation,the demand for substation primary equipment online monitoring is increasing,and the requirements for monitoring technology are also increasing.In practical application,the multiple electrical parameters and operations of multiple primary equipments in the same substation need to be transmitted to the monitoring center in real time.But current monitoring IEDs are relatively independent,their data acquisition and communication interface specifications vary,thus making the installation and operation more complex.This paper studies and designs an integrated embedded monitoring IED which can be used to monitor a variety of primary equipment parameters,and it's embedded in IEC61850 standard protocol.The results of experiment and operation show that the integrated monitoring IED is simple in installation and reliable in operation.It can reduce the construction cost,save the installation space of the monitoring IED and improve the stability of the monitoring system.
