The model was trained with main steam flow values of one 660MW unit.The calculation results testified that the double BP neural network model improved the forecasting accuracy of a single model.The mean relative forecasting error of checking samples data was 1.5%, while the mean relative forecasting errors of regression neural network and time-delay neural network were 2.7% and 1.9% respectively.It was proved that the double BP neural network combined model had preferable forecasting accuracy and can be applied for validation of real-time data in power plant.Read More
