Abstract
In order to improve the accuracy of voltage sag source identification,a voltage sag source identification method based on the improved whale optimization algorithm(IWOA)optimized support vector machine(SVM)is proposed.Firstly,by using S variable losses to process the voltage signal,16 feature quantities are obtained for voltage sag source identification.Secondly,multiple mea-sures such as population chaos initialization,nonlinear convergence factor,and Cauchy mutation are adopted to improve the whale op-timization algorithm,resulting in the IWOA algorithm with better convergence performance.The IWOA algorithm is used to search for the optimal parameter values of SVM,and a voltage sag source identification model based on IWOA-SVM is constructed.Six different categories of voltage sag disturbance signals are used for example analysis.The results show that the recognition accuracy of the IWOA-SVM model is as high as 98.33%,and the recognition effect is better than other methods,verifying the effectiveness of the proposed voltage sag source identification method.关键词
