Study on application of parallel connection Artificial Neural Network to hydraulic turbine test

针对水轮机试验中需要对试验结果进行整理的问题,提出了应用双并联前向人工神经网络建立水轮机特性数学模型的方法.用双并联前向人工神经网络建立的水轮机特性数学模型具有表达简单、精度高等特点,同时还可以对试验成果进行一定的修正,能满足实际应用需要.

In accordance with the problem that the testing results need to be processed during the test of hydraulic turbine,the method of establishing a mathematical model of the characteristics of hydraulic turbine with the parallel connection feed-forward Artificial Neural Network is proposed.Because the model has the character of simple expression with high precision,and moreover,the model can make certain modification of the testing results to meet the requirement of the actual application as well.
