基于改进鲸鱼算法优化的接地网腐蚀速率预测
Corrosion Rate Prediction of Grounding Grid Based on Improved Whale Algorithm Optimization
摘要
Abstract
In order to improve the accuracy of predicting the corrosion rate of substation grounding grids and solve the problems of traditional BP(Back Propagation)neural networks easily falling into local optima and traditional algorithms randomly initializing populations affecting prediction accuracy,this study proposes an improved whale opti-mization algorithm to optimize the BP neural network for predicting the corrosion rate of substation grounding grids.An improved whale optimization algorithm is developed using chaotic mapping to initialize whale population,impro-ving nonlinear factor to adjust adaptive weights,and enhancing search by Levay flight.Corrosion prediction model of grounding grid based on the improved whale optimization algorithm to optimize the BP neural network is established.The corrosion data of grounding network of 72 substations are simulated and analyzed.The results show that the aver-age relative error of the improved model is 1.84%,the global maximum relative error is 3.86%,and the root-mean-square error is 0.139 02,which is significantly lower than that of the traditional model,proving the feasibility of the proposed model.关键词
