Renovation of Synchronous Phasor Measurement Unit (PMU) in Dachaoshan Hydropower Station

2018年4月至12月,大朝山水电站利用机组停机及220kV系统、500kV系统停电检修的有利时机,进行了同步相量测量装置(PMU)的升级改造。据了解,大朝山水电站为云南省首座使用该套同步相量测量装置的水电厂。主要介绍了更新改造过程中的各个重要节点的重点事项,遇到的困难和解决的方式,遗留的问题及应对的方法。目前,更新改造工作已完成,装置投运正常。

From April to December 2018, Dachaoshan Hydropower Station upgraded the synchronous phasor measurement unit(PMU) by taking advantage of the opportunity of unit shutdown and outage maintenance of 220 kV system and 500 kV system. It is understood that Dachaoshan Hydropower Station is the first hydropower station in Yunnan Province to use the synchronous phasor measurement device. This paper mainly introduces the key points of each important node in the renovation process, the difficulties encountered and the ways to solve them, the problems left behind and the ways to deal with them. It has reference significance for the renovation of the same type of equipment in brother power plants. At present, the renovation work has been completed and the plant has been put into operation normally.
