Description
Summary:This paper presents an investigation on a voltage regulator for parallel operated isolated synchronous generators supplying 3-phase 4-wire loads driven by constant speed prime mover like diesel engine, bio-mass, gasoline, hydro turbine unit etc. The proposed voltage regulator is realized using a STATCOM (static compensator) for providing the reactive power compensation, and load balancing. Three single-phase thyristors based VSC along-with three single-phase transformers and self supporting DC bus is used as a voltage controller for supplying 3-phase 4-wire loads. The neutral point of the load is achieved using neutral point of the excitation capacitors and primary windings terminal of the transformers. The proposed isolated electrical generating system is modeled and simulated on MATLAB using Simulink and PSB (Power System Blockset) toolboxes. The performance of proposed voltage controller for isolated synchronous generators is demonstrated while feeding loads.
