Study On Control System Of Standby Diesel Generator In Passive Nuclear Power Plant

With the development of China's nuclear industry,the passive nuclear power station has a wide prospect in domestic and foreign nuclear market.Standby diesel generator set provided in station shall supply power to loads during a loss of offsite power event to achieve the defense-in-depth function and prevent unexpected operation of passive protection system.As the core component of DG set,the control system shall command the DG set to start / stop in various conditions and protect the DG set when fault occurs.The control system shall be consistent with advanced equipment,high reliability and clear control logic.The thesis is focused on the control system of DG set,and defines the equipment composition and performance requirement according to the system and component requirement of plant.The thesis also researches the reliability,control logic and protection configuration of the control system.The rationality of system design is verified by simulation modeling.Through the research above,the thesis is to lay a technical foundation of localization.
