【Abstract】 In this paper,the overspeed trip performance of the 600MW air-cooled steam turbine-generator unit was calculated and analyzed using the Overspeed Calculation Program. The influence of the valve signal time delay,the valve closing time,the mass moment of the rotor train and some other factors were considered.The main factors that influence the overspeed performance were discussed.The safety and reliability of the unit were strengthened through the analysis of the overspeed performance of the unit.更多还原
