Abstract
This paper deal with comparative analysis of PI(proportional-integral) based STATCOM (Static Compensator) and DVR (dynamic voltage restorer) for power control of a prime mover operated at a constant speed isolated asynchronous generators (IAG) powering three-phase linear and non-linear load. Biomass, Biogas, gas-turbine, Diesel engine like SEIG stands for self-excited induction generator powered by prime mover operating at a constant speed used for isolated control generation has an issue with the voltage regulation. The DVR is a parallel voltage controller, which the system by adding voltage in series constant source and voltage at load. Other side STATCOM is a shunt voltage controller, which inject current into the system for maintain constant source voltage. The DVR and STATCOM controllers are modelled utilising a self-supporting DC bus and a voltage source converter (VSC) that utilises an IGBT (Insulated Gate Bipolar Junction Transistor) as its foundational component. The SEIG-based 7.5Kw, 415V, 50Hz producing system has Simulink, the toolbox for the power system block set (PSB), as well as DVR and STATCOM modelling and simulation are done in MATLAB.
