摘要
介绍了遗传算法及其在火电厂热工控制中如何用于模型对象参数的辨识。采用遗传算法对脱硝反应器出口氮氧化物的流量响应的传递函数参数进行辨识,取现场数据进行拟合,比较拟合效果和传递函数的准确性。通过仿真得出了出口氮氧化物流量响应对于喷氨流量变化的传递函数,为SCR脱硝反应器的控制仿真研究提供依据。
An introduction of Genetic Algorithm and how it be used in parameters identification of model objects in the power plant thermal control.A genetic algorithm is adopted to identify the parameters of transfer function,which show the response of nitrogen flow in the outlet of reactor denitrification.Take the field data and fitting,then compare the fitting effect and the accuracy of the transfer function.Through the simulation,a transfer function is got about how the nitrogen oxides flow in export reflect by changing the injection ammonia flow.It provides a basis to research the simulation about the SCR denitrification reactor control.
