    Abstract: Aiming at the event that after grade C overhaul of unit 2, the units was unable to connect to the grid because of the open phase protection misoperation, this paper introduced the taking place process and trouble shooting process of the event, analyzed the possible cause of the event and raised the making control circuit design of improving the grid connection switches, strengthening the corresponding period checking of the grid connection switches making and breaking and the unblocked examination of hydraulic operating mechanism oil circuits and supplying the regulation of the grid connection switches transmission test management details etc measures to prevent similar accident from taking place.
           Key words: generator set; open-phase protection; grid connection; precautionary measures
