基于免疫原理的RBF神经网络模型在汽轮机排汽焓计算中的应用

Calculation of Steam Turbine's Exhaust Enthalpy by Using the Immune Radial Basis Function Network

根据汽轮机末级排汽焓与其影响因素之间的映射关系,提出了一种基于免疫原理的RBF神经网络模型来计算汽轮机的排汽焓。计算结果表明,该模型收敛速度快,运算简便,预测精度较高,具有一定的工程应用价值。

According to mapping relationship of the steam enthalpy of the turbine＇s exhaust and its effction, a mathemtical model based on the Immune radial basis function network was established. It can be used the steam enthalpy of the turbine＇s exhaust. The applicationof the model shows that the proposed method is featured by swiftness, accuracy and ease of practical application.
