Steam turbine closed water system with APS one-key start and stop function

The invention discloses a steam turbine closed water system with an APS one-key start-stop function, which is characterized in that a master controller and an intelligent default automatic selector are configured to divide the start-stop process of the steam turbine closed water system into standardized steps, configuration is carried out in a logic picture, and the start-stop process of the steam turbine closed water system is controlled through logic and parameters. The one-key start and stop function of the steam turbine closed water system is achieved, the start and stop process is divided into a start stage and a stop stage, the start stage is composed of four steps, the stop stage is composed of three steps, and completion of the previous step serves as a precondition for starting of the subsequent steps. The turbine closed water system has the logic function of APS one-key start and stop, the burden of operators is relieved, monitoring is more convenient, the working efficiency of the operators is impr
