摘要
为了准确、有效的预测水电站大坝大体积混凝土浇筑的冷水管内部污垢的累积规律,设计了一种基于K均值算法和Chebyshev神经网络相结合的污垢预测模型。利用改进的神经网络预测污垢系数时,具有算法简单、收敛速度快的特点。改进的Chebyshev神经网络模型提供了一个预测污垢系数的有效方法,且具有较好的预测能力;在相同的精度下,该方法的收敛速度优于一般的神经网络。
In order to accurately and effectively predict the accumulation of fouling in the cold water pipes of large-volume concrete pouring of hydropower dams,a fouling prediction model based on the combination of K-means algorithm and Chebyshev neural network is designed.When the improved neural network is used to predict the fouling coefficient,it has the characteristics of simple algorithm and fast convergence.The improved Chebyshev neural network model provides an effective method for predicting the fouling coefficient,and has good predictive ability.Under the same accuracy,the convergence speed of this method is better than the general neural network.
