Abstract
The present thesis introduces a novel design as well as the performance of a stand-alone Dual Stator Winding Reluctance Generator (DSWRG). The proposed generator is suitable for operation at high speed since it has a brushless construction. It also has a rigid construction whereas its rotor has neither windings nor a permanent magnet set. In this design there are two sets of windings that are embedded in the stator slots. One, referred to as multi-phase power winding, which supplies power to the load. The other winding, called the excitation winding, is connected directly to a dc supply. Different rotors are designed with different shapes to suit the operation at high speeds and to give maximum generated power. The proposed DSWRG generates a sinusoidal voltage waveform with a frequency equal to double the frequency obtained from the conventional synchronous generator with the same number of rotor poles and speed. The machine performance has been measured and compared to the results obtained from a MATLAB SIMULINK model.
More over a brushless mixed pole- low cost- constant frequency- generator has been developed. This generator gives a constant frequency whatever the rotor speed. No controllers are needed, so that, it may be expected to be a low cost generator and is expected to need a low maintenance since it has a brushless construction.
The present thesis consists of the following:
• Chapter (1) gives a general introduction about generators development and gives the relative advantages and disadvantages between the different types. In addition, the thesis objectives are outlined.
• Chapter (2) gives a description of the proposed dual stator winding reluctance generator, the winding function analysis technique for inductance calculation and the theory of operation of the proposed machine.
• Chapter (3) presents the dynamic model, by which the dynamic behavior of the proposed machine can be simulated.
• Chapter (4) presents the basic equations required for sizing the DSWRG and gives a design example, through finite element, to verify the proposed technique.
• Chapter (5) presents the experimental and simulation results for a DSWRG prototype with two rotor types, named salient pole rotor and flux barrier rotor and a comparison between the two rotor is also presented.
• Chapter (6) presents the basic theory, construction and an experimental verification for the separately excited –constant frequency-mixed pole induction generator. Also, the advantages of this generator relative to other generators are presented.
• Chapter (7) presents the conclusion and future work.
