牵引变电所馈线保护误动研究

Study on Miss-operation for Protection of Feeders in Traction Substation

针对运行中牵引变电所出现的馈线保护误动现象,从理论上进行了各方面分析,并最终找出原因,解决了变电所馈线保护误动。文中列举了牵引变电所计算实例,阐明了如何进行整定计算和校验,进一步贴近现场和增强现场的可操作性。

To counter with the feeder protection of miss operation in the transformer substation, executes overall analysis in term of theory and finds out the reasons of this improper reaction and the final solutions to it. The paper gives actual examples for computation of substation and illuminates the ways to conduct setting calculation and verification that will come close to the site and enhance the site operation.
