Investigations on modular three phase power factor control schemes using DC DC quadratic boost converter in low power wind energy conversion system

Abstract

Electricity is an essential element of modern life and serves as the newlinefoundation of present-day industrial society. With the global shift towards newlineadopting green energy practices and decreasing reliance on fossil fuels, which newlineare the primary contributors to greenhouse gas emissions and global warming, newlinethe utilization of renewable energy sources that produce minimal pollution is newlineunavoidable. The depletion of fossil fuels poses a significant risk to global newlineenergy security. There is a pressing necessity to utilize alternative sources of newlineenergy that are abundant, renewable, promote good health and well-being, newlineand are environmental friendly by emitting minimal greenhouse gases. To newlinesummarize, renewable energy serves as an alternative form of energy as it is newlinehighly reliable and sustainable. The method of generating electrical energy is newlineclean, safe, and efficient, and the omnipresence of wind makes it an excellent newlineresource for constructing standalone towers in remote locations. It is a newlinecontinuous source of energy that is not dependent on the cyclical pattern of newlineday and night. Wind speed around the selected region is estimated using newlineHomer-Pro software, and the presence of faults is analyzed using the Wavelet newlineDecomposition Technique. Faults including open circuit, line-to-line, module newlineloss, and phase unbalances are detected employing Discrete Wavelet newlineTransform, and a separate fault repository is created to classify faults with the newlinehelp of a detailed coefficient table for various fault scenarios. The Quadratic newlineBoost Converter (QBC) is compared with the Boost Converter (BC) and newlineCascaded Boost Converter (CBC) based on switch and diode stress, voltage newlinegain, and ripple factor. QBC is chosen for its ability to provide high voltage newlinegains during wind speed variations. This research work endeavours to develop newlinea proficient DC-DC QBC converter customized for Wind Energy Conversion newlineSystems (WECS), guaranteeing continuous DC output even in scenarios of a newlinemodule failure, and providing a near unity power factor.
