【摘要】 本文利用有限元数值计算的结果作为训练样本 ,得到某 3 0 0MW电站锅炉的汽包应力自适应模糊网络 (ANFIS)模型。该应力模型继承了有限元数值的精度 ,并可以用于实时计算。利用该应力模型 ,本文探索了汽包启动初始升温率和汽包应力谷值之间的关系 ,给出了一个自寻优的启动优化算法。算例表明该算法可以在不减少启动寿命损耗的前提下明显缩短启动时间更多还原

【Abstract】 In this article a stress ANFIS model of boiler drum is built by training them with the result of finite element method.This ANFIS model can run real-time and inherits the same precision of finite element method.Using the ANFIS model the relationship between initial rising rate and stress valley in boiler startup can be obtained,and an adaptive optimization method of boiler startup is developed.An example shows it can shorten the boiler’s time greatly without increasing its life loss.更多还原
