A New Method for Power Quality Events Detection and Classification using Discrete Wavelet Transform and Correlation Coefficients

Navid Ghaffarzadeh

Volume 4, Issue 1 , January 2021, , Pages 47-57


  In this paper a novel and simple approach for detection and classification of wide variety range of power quality(PQ) events based on discrete wavelet transform (DWT) and correlation coefficient is presented. For this purpose, two new indices is proposed and by comparing the values of the correlation ...  Read More

A New Whale Optimization Algorithm Based Fault Location Method by Focusing on Dispersed Model of the Transmission Line

Navid Ghaffarzadeh; Hossein Faramarzi

Volume 3, Issue 4 , September 2020, , Pages 393-406


  In this paper, a fault location approach is presented by using Whale Optimization Algorithm (WOA) strategy in two terminal transmission feeder. Also, Grey wolf Optimization (GWO) method is discussed. From both ends, affording the preparatory data for proposed strategies voltages and currents from both ...  Read More
