Abstract
Faults in regenerative heat system of the power plant have been analysed
and a new fault diagnosis model based on levenbergMarquardt (LM) neural network for regenerative heat system being put forward. The LM algorithm is a combination of the gradient decent algorithm with the GaussNewton algorithm. Results of simulation show that the new model has greatly reduced the training time and the tracking error
having very high accuracy
being more superior than traditional BP neural network algorithm model
