PROJECT TITLE :
Design, Modeling and Control of a Novel Hybrid Excited Flux Bidirectional Modulated Generator Based Wind Power Generation System - 2017
This paper proposes a novel hybrid excited generator, that is appropriate for a variable-speed wind power generation system. Two sets of excitation sources are utilized, that are permanent magnets (PMs) on the rotor and the sphere windings on the stator. The rotor is design with PM-iron structure, specifically the PMs and iron poles are alternatively located in rotor, which can provide PM excitation and flux modulating simultaneously. Meanwhile, the adjacent stator teeth are designed with completely different height, that allows the stator with flux modulating effect, and, thus, bidirectional flux modulating can be achieved. Some specific harmonics excited by the rotor PMs will be effectively adjusted by the field current, and the rear electromotive force and electromagnetic torque will be regulated accordingly. So, the proposed generator can achieve constant voltage control and most power purpose tracking management by controlling the field current. The design issues and field regulating principle are analytically investigated. An improved Tabu search algorithm is employed to optimize the proposed generator, and finite-element method is employed to understand preliminary study of the electromagnetic performances. A prototype is manufactured and experimental tests are conducted to verify the theoretical analysis and management strategies.
