چکیده
PQ analysis for detecting power line disturbances in real-time is one of the major challenging techniques that are being explored by many researchers. In order to understand the causes of electronic equipment being damaged due to disturbances in power line, there is a need for a robust and reliable algorithm that can work online for PQ analysis. PQ signal analysis carried out using transformation techniques have its own advantages and limitations, In this work, Mathematical models for various PQ signal disturbances is developed and validated against real time signal. Based on the mathematical models developed, performances of various transformation techniques are compared. Software reference models for transformation techniques are developed using MATLAB. The developed models are verified using various signal disturbances. Keywords— Power quality, Power system transients, discrete wavelet transforms. Lifting based wavelet transform.

This paper presents a new framework based on modified EMD method for detection of single and multiple PQ issues. In modified EMD, DWT precedes traditional EMD process. This scheme makes EMD better by eliminating the mode mixing problem. This is a two step algorithm; in the first step, input PQ signal is decomposed in low and high frequency components using DWT. In the second stage, the low freq...
