Investigation Of Switched Reluctance Generator Used In Wind Power System

Now, energy sources consume increasing daily and environment empoison being serious gradually, wind power, as renewable, no pollution energy source, is paid great attention by more and more countries. The technologies also become research hotspot of many countries's scholar.This paper mainly focuses on the application of switched reluctance generator in wind generation, and has done all-around study, from simulation to experiment, from theory to practice.Firstly, this paper summarized and analyzed the present and the prospective of wind generation and relative techniques based on a large number of referenced materials, presented the several advantages of SRG wind generation system, and further made the significance of developing this kind of system clear.Secondly, the basic theory of SRG is deeply studied in detailed. Two operation modes of SRG were pointed out, the linear mathematic model of SR generator was discussed, and three control methods of SRG were pointed out. In addition, this part studied the structure, the idea of tracing and capturing maximal wind energy and control scheme of the switched reluctance generator wind power generation system.Thirdly, the mathematic and simulation models of SRG system were established and discussed in details. And some instructive theoretic conclusions were drawn from the above work.Fourthly, a set of practical SRG system is developed, which based on DSP control technique and power electronics converting technique. The reasonable design of this system fully displayed the flexibility of SRG control.Finally, experiments have been done on this practical system. The experimental results validated and deepened the conclusions drawn from theoretical research. The compare between the results from experiments and simulation also testified the practicability of the mathematical models presented in this paper.
