To understand the neutral-bus switch reclosing accident due to the action of high-speed neutral-bus switch protection(code: 82HSNBS)in a lightning strike on Chu-Sui HVDC transmission system
the action process of the high-speed neutral-bus switch protection and the cause are analyzed in detail according to the wave records of the accident. A transition optimization scheme of frequency restricting and resetting is hence presented. Simulation results show that the optimization scheme is effective and feasible.
