主　　题：nozzle governing steam-excited vibration operation optimization unit efficiency 

摘      要：Based on tests and theoretical calculation an optimum steam admission mode is proposed which can effectively solve the steam-excited *** operation mode jointly considering the valve point and operation load is proposed based on the analysis and study of a large number of unit operation optimization *** to the steam-excited vibration that occurs during the optimization process when the nozzle governing steam turbine switches from a single valve to multi-valves a steam admission optimization program is *** comprehensive program considering the steam-excited vibration is applied to a 600 MW steam turbine unit to obtain the optimum sliding pressure curve and the optimum operation mode and the steam-excited vibration is solved successfully.
