Investigations on Power Quality Disturbances Using Discrete Wavelet Transform
Extensive use of power electronic devices and non-linear loads in electrical power system cause problem of power quality (PQ). Renewable energy sources are also integrated to the grid through power electronics based equipment. So the power quality issues are drawing attention in recent years. PQ disturbance need to be detected accurately It is also essential to find out the cause of such an eve...
متن کاملWavelet Transform for Processing Power Quality Disturbances
The emergence of power quality as a topical issue in power systems in the 1990s largely coincides with the huge advancements achieved in the computing technology and information theory. This unsurprisingly has spurred the development of more sophisticated instruments for measuring power quality disturbances and the use of new methods in processing and analyzing the measurements. Fourier theory ...
متن کاملAutomatic Power Quality Disturbances Detection and Classification Based on Discrete Wavelet Transform and Support Vector Machines
In this paper some patterns based on discrete Wavelet transform are studied for detection and identification of both, low frequency disturbances, like flicker and harmonics, and high frequency disturbances, such as transient and sags. Daubichies4 Wavelet function is used as a base function to detect and identify due to its frequency response and time localization information properties. Based o...
متن کاملAutomatic Detection and Positioning of Power Quallity Disturbances using a Discrete Wavelet Transform
Voltage sag is one of the crucial problems of power quality that affects high power devices. It may cause sensitive devices to malfunction and may increase the failure in power systems. An appropriate algorithm for identifying and positioning the voltage sag disorder is suggested in this study. This procedure identifies the voltage sag online and automatically and can identify the exact time an...
متن کاملClassification of Power Quality Disturbances Using Wavelet Transform and S-transform Based Artificial Neural Network
This paper presents features that characterize power quality disturbances from recorded voltage and current signals using wavelet transformation and S-transform analysis. The disturbance of interest includes sag, swell, transient and harmonics. A 25kv distribution network has been simulated using matlab software. The feature extraction has been done using wavelet transformation and S-transform,...
