Unit self-optimizing thermal power plant start-stop control logic implementation

The present invention proposes a Power Generating Unit from the start-stop control hierarchical optimization logic implementation. The method employed by designing monitoring mode, breakpoint mode, skip mode, and a start and stop key different from the start and stop of the operation mode switching and management logic; variable constraint and a soft and flexible control structures, hard breakpoint serial and parallel combinations of branched, supplemented by a variety of dynamic anticipation, alarm conditions, effective to improve the utility and applicability unit from start-stop control function, since the start-stop function simplifies the control system and user interface.
