1. an One-key start-stop control system for fuel for Combined cycle gas-steam turbine unit, described Combined Cycle Unit at least comprises combustion engine and combustion engine backup system, steam turbine and steam turbine backup system, also comprises waste heat boiler, BOP system and synergic system;

  • Described One-key start-stop control system for fuel covers described combustion engine and combustion engine backup system, described steam turbine and steam turbine backup system, described waste heat boiler, described BOP system and described synergic system;

    Described One-key start-stop control system for fuel is step control structure, is followed successively by unit cooperative level control module, subgroup level control module and device level control module from upper strata toward lower floor;

    In the sequence logic of described unit cooperative level control module, subgroup level control module, all bypass structure is set;

    Namely subgroup level control module is when starting sequence without the need to performing the equipment full cut-off state that relates to from this subgroup, and subgroup logic can according to the current state shielding of equipment by the step sequence operated;

    The startup of described One-key start-stop control system for fuel controls to comprise successively subsidiary engine in described BOP system and starts, the upper water of described waste heat boiler, the startup of described combustion engine is grid-connected, described bypass structure coordinates described waste heat boiler increasing temperature and pressure, the red switch of described steam turbine, warming-up and grid-connected, described Combined Cycle Unit according to the operating mode of boiler and steam turbine by given pace load up to basic load;

    It is characterized in that;

    artificial judgment point and the confirmation point of described One-key start-stop control system for fuel all adopt a control mode for automatic Logic judgment;

    The startup control section employing time parameter of described One-key start-stop control system for fuel or on-line chemical analysis instrument parameter are directly introduced as the judgement to " Steam-water Quality is qualified " in steering logic.
