摘要
以1台600 MW机组的断路器非全相及失灵保护负序和零序过电流元件的整定计算为例,探讨负序和零序过电流元件的整定计算方法,并对各种非全相运行情况下的负序和零序过电流元件的灵敏性进行分析。
Based on a 600 MW generator, this paper introduced the setting calculation of negative-sequence and zero-sequence over current components in generator transformer group open phase and malfunction protection, studied the method of setting calculation of negative-sequence and zero-sequence over current components, and analyzed the sensitivity of negative-sequence and zero-sequence over current components under all open-phase operating situations.
