Optimization of Coordinated Control Scheme for IGCC Power Plants

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.
