摘　　要：根据IGCC电站中主要环节的动态模型,设计了以气化岛跟随为主的协调控制方案,并采用多目标遗传算法对控制系统参数进行了优化。仿真结果表明,该方案不仅可以快速跟踪负荷设定值的变化,也可以维持饱和器压力的稳定;参数优化后,控制性能指标有所降低,但控制品质有了明显提升。Based on dynamic models for main loops of IGCC power plant,a coordinated gasification island follow type control scheme was designed,while an optimization performed to parameters of relevant control systems using multi-objective genetic algorithm.Simulation results show that via the scheme,not only the varying settings of load can be traced rapidly,but also the saturation pressure can be kept stable.Although the performance index of the controller may numerically drop to some degree after parameter optimization,the control quality will have a great increase.
