摘要
针对一起35 kV系统备自投保护的拒动作,通过理论分析,得出了在大电流系统下适用的备自投逻辑,且在小电流接地系统中却并不能在所有工况下正确动作。在此基础上,提出了相关的改进措施和解决方案,以确保备自投的正确动作。
According to the theoretical analysis of an operation failure of BATS in a 35 kV system, a fact can be got that the BATS can operate normally every time in directly grounding power system, but cannot operate correctly in indirectly grounding power system. Some relevant solutions were proposed to ensure the normal operation of BATS in indirectly grounding power system.
