| Abstract: | In the light of the existing connection methods and protection configuration of regional power network, this paper analyzes the operation reliability of substations with duplicate 220 kV supply, line-transformer unit substations and substations with power supply from the receiving-end system in 110 kV power network under different operation and failure modes. Measures of using automatic stand-by power switching devices and auto-reclosing devices with protection values reasonably set are proposed to solve the problems in operation, the efficacy of which has been validated in the operation of substations in Huizhou power network. |
