摘　　要：电网中变电站由于单主变运行或因为检修、故障等非正常运行方式可能导致变电站因失去主电源,造成全站失压的事件时有发生。国网黄山供电公司专业技术人员结合国内外母线失压负荷转移的现状,提出10 kV母线失压自动进行馈线负荷转移供电(母线自愈)的方案。实践证明,该方案具有可行性,并可以推广至其他供电公司使用,显著提高了客户的用电获得感。In the power grid,when a single main transformer substation or substation operates with a single power supply due to maintenance,fault and other reasons,the event of voltage loss of the whole station due to loss of the mainpower supply may occur from time to time.Professional and technical personnel of State Grid Huangshan Power Supply Company,combining the situation of bus voltage loss load transfer at home and abroad,proposed a scheme of automatic feeder load transfer power supply(bus self-healing)for 10 kV bus voltage loss.The practice proves that the scheme is feasible and can be extended to other power supply companies.Significantly improved customers'perception of electricity use.
