可根据前3个清洗周期某时刻的数据来预测下1个周期该时刻的清洁系数
依据所需的输入参数
即可实现在线预测凝汽器的清洁系数。
Abstract
The gray model
neural network model and series gray neural network model were employed to predict the water side clean coefficient of the condenser tubes in a power plant.The results showed that
the series gray neural network model was superior to the single prediction model.Its predicted value was closer to the true value
and the error was controllable during the network training process.So it is feasible and effective to predict the water side clean coefficient of the condenser tubes by applying this model.In practical applications
we can predict the clean coefficient at some time according to the one at the time in the first three cleaning cycles.By the required input parameters
the online prediction of water side clean coefficient of the condenser tubes can be realized.
