Certain investigations on enhancing voltage profile and compensating fluctuations with custom power system devices for voltage sensitive equipment

Abstract

Voltage fluctuations and low voltage profiles pose persistent newlinechallenges in industries, leading to equipment damage, costly downtime, and newlinereduced productivity. Traditional voltage compensation devices, such as servo newlinestabilizers, often fail to provide efficient and timely correction due to their newlineslow reaction times and reliance on capacitors by a Dynamic Voltage Restorer newline(DVR). Additionally, the integration of solar photovoltaic (PV) systems with newlinevoltage compensators is often complex and costly, as separate units are newlinetypically used. newlineThese issues emphasis the need for novel voltage compensation newlinesolutions that can effectively mitigate voltage fluctuations and maintain stable newlinevoltage at the Point of Common Coupling (PCC) in industries. newlineThe thesis provides solution to the persistent voltage issues in newlineindustrial environment and proposes novel voltage compensation solutions to newlineenhance grid stability. The research focuses on mitigating voltage fluctuations newlineand maintaining unity power factor at the Point of Common Coupling (PCC) newlineand integrating solar photovoltaic (PV) systems for improved grid stability newlineand reliability. newlineThe research investigates the integration of a solar PV inverter, Static newlineSynchronous Compensator (STATCOM), and DVR into single equipment. newlineThese equipment s are typically used separately for maintaining Unity Power newlineFactor (UPF) at the PCC, compensating for voltage fluctuations, and for newlineexporting solar power to the grid. By integrating them, significant reductions newlinein installation and maintenance costs can be achieved, along with improved newlinesystem performance. newline
