摘要: 某发电公司的小容量发电机变压器组没有配置专用故障录波器,不符合DL/T 553—1994《220~500kV电力系统故障动态记录技术准则》的规定,为此提出了改进方案。从接入故障录波器的模拟量、安装位置、故障录波器数量、模拟量接入位置及二次电缆的长度等方面入手,对各种改进方案进行了分析比较,推荐并实施了最佳改进方案。

Abstract: In a power generation company, the dedicated fault recorder was not configured for the smallcapacity generatortransformer set, and this does not accord with the rule of the file DL/T 553—1994, ‘The technical criteria for transient fault recording in 220~500kV power system’. Therefore, several improvement plans were put forward. Various improvement plans were analyzed and compared with each other from many aspects, such as the analog variable connected into the fault recorder, the installation sites, the number of the fault recorders, the access positions of the analog variables and the length of the secondary cable. The best improvement plan was recommended and implemented.
