摘要
在对三峡电站 1号发电机所有可能发生的同槽和端部交叉故障进行仿真计算的基础上 ,对两套零序电流型横差保护、不完全裂相横差保护、两套不完全纵差保护的组合的灵敏性与两套零序电流型横差保护、传统裂相横差保护、两套不完全纵差保护的组合的灵敏性进行了对比和分析 ,在此基础上提出了 1号发电机内部故障主保护的总体配置方案。
Based on the simulation of all kinds of slot and end faults of No.1 generator in the Three Gorges Power Station, the paper analyzes the difference of sensitivity between the combination of two kinds of zero-sequence current transverse differential protection, incomplete split-phase transverse differential protection and two kinds of incomplete longitudinal differential protection and the combination of two kinds of zero-sequence current transverse differential protection, traditional (complete) split-phase transverse differential protection and two kinds of incomplete longitudinal differential protection. Then the main protection scheme of internal faults is proposed for No.1 generator in the Three Gorges Power Station.
