Abstract
In order to improve the quality of coordinated control system, set point value with multi-objective optimization has been widely cause the attention of researchers. However, the accuracy of the feasibility regions for the decision variables in fitness function is the foundation of the multi-objective optimization, and have an important influence to multi-objective optimization results. Take a 600 MW coal-fired unit as an example, according to the system mechanism builds a boiler-turbine dynamic model. And present a method, in this paper, which is using the iteration way and observing its physical constrain to determine the feasibility regions of control variables. The simplified model uses fuel quantity, turbine valve value and feedwater valve value as the control variables, to get the region of the pressure and control variables during 50%-100% load.
