Abstract
In order to grasp health status of photovoltaic(PV)modules in real-time
an online health diagnosis model based on Takagi-Sugeno(T-S) fuzzy neural network is proposed.Firstly
electrical output of common PV modules under abnormal operating conditions is analyzed and feature vectors are selected.Then use fuzzy C-means(FCM)and adaptive LM algorithm to optimize the T-S fuzzy neural network.Final simulation experiment proves the feasibility of the model.The results show that the diagnostic accuracy of this diagnostic method reaches 94 %
and the diagnostic precision and convergence speed prior to the traditional T-S fuzzy neural network model.
