Application of Generalized Regression Neural Network to Transformer Winding Hot Spot Temperature Forecasting
摘要
Abstract
The winding hot-spot temperature of transformer is the key factor which affects the insulating performance,so it is necessary to forecast the transformer winding hot spot temperature so as to improve the operational reliability of transformer.However,the inner temperature of transformer is affected by many factors,and the heat transfer,fluid mechanics,electromagnetism and other interdisciplinary increase the complexity of calculation.Generalized regression neural network(GRNN) has strong nonlinear mapping capability,flexible network structure,high fault tolerance and robustness,etc,and adopting GRNN to predict the hot spot of transformer winding will overcome the shortcomings of back propagation neural network(BPNN),such as the local minimum and low convergence speed and so on.Comparison of the results of GRNN and the measured data show that the results of GRNN are in accordance with the measured values.关键词
