Abstract

The invention relates to an automatic start-up and shut-down optimization control system of a heat-engine plant unit plant. The automatic start-up and shut-down optimization control system is characterized in that: a basic control logic generated by data communication system (DCS) standard control algorithm configuration is operated in a DCS process controller and applied to the automatic control of processing equipment and processing parameters in the start-up and shut-down process of the unit plant, and operated in optimization calculation software of an optimization controller and applied to online optimization calculation of a key processing parameter target value and a target value change rate in the start-up and shut-down process of the unit plant as well as fitting and learning of a multi-target optimization control law; a bidirectional data communication function is formed between the optimization controller and the DCS, so acquisition of DCS data can be finished; and an optimization calculation result is written into a DCS real time database so as to realize online optimization. An automatic start-up and shut-down control system is implemented by combining four functions, namely basic control, optimization calculation, communication interfaces and online optimization, so that the practicability and the applicability of the automatic start-up and shut-down optimization control system are improved greatly.

Description

technical field [0001] The invention relates to an optimization control system of an industrial production process, in particular to an on-line optimization control system for automatic start-stop of a thermal power plant unit unit, which belongs to the field of industrial automatic control. Background technique [0002] The unit automatic start-up and stop control system (English: Automatic Plant Start-up&Shut-down System, also referred to as APS) is the highest level of control function in the unit unit automatic control system of thermal power plants. During unit startup and shutdown, APS receives signals from control systems such as unit closed-loop control system MCS, steam turbine digital electro-hydraulic regulation system DEH, boiler combustion control system BMS, boiler / steam turbine sequence control SCS, electrical control system ECS and other control systems, and according to the conditions A complete set of APS control logic including judgment, timing, calculatio...
