In order to make the gas-steam combined cycle unit realize quick startup/stop and safe and effi-cient operation,the bypass system full pressure control strategy was designed,according to the structure and characteristics of the unit bypass system.Through this control strategy,the problems affecting the unit economic efficiency,such as the conventional bypass control system can not achieve full automatic control, long startup period of the gas turbine and huge steam loss,were solved.
