【Abstract】 In view of the fact that thermal power units take charge of load regulation at present, this paper presents a new boiler-turbine load coordinated control system in which the radiant energy signal detected from furnace is taken as an intermediate control variable and a feedback signal to combustion rate in boilers. The results of simulation show that the new control strategy can improve the load tracing performance, overcome efficiently the influence of the boiler combustion rate disturbance on the units operation and enhance obviously the control quality. In addition, the new control system can be taken into practice in engineering easily.更多还原
