| Wind power is a flexible maneuver,safe and reliable power generation.However the wind energy is fluctuate and random,it makes the application of wind power integration blocked and resulted in serious wind damage caused by the phenomenon.Domestic experts put forward non-grid-connected wind power applications in order to avoid such phenomenon continue to deteriorate,which is directly applied to high energy consumption.It is not only to stabilize the impact of wind power on the grid,but also to enhance the utilization of wind power and reduce the cost of wind power.As a new type of generator,Switched Reluctance Generator(SRG)has the characteristics of low cost,simple structure and adapts to harsh environment.It has great potential in the field of wind power generation,and the corresponding research of SRG is more and more.If SRG is used to supply power for non-grid-connected DC load,the wind turbine will be largely simplified,the utilization of wind energy can also be effectively improved,and promote the rapid development of wind power industry,bringing great economic benefits.In this paper,the development status of SRG is introduced,and three kinds of high-energy DC load characteristics are analyzed.It is proposed to use switched reluctance wind generator to supply power for such DC loads.Secondly,the parameters of SRG are designed and optimized for the purpose of improving the SRG's efficiency by the MathCAD calculation software and Ansoft Maxwell 16.0.The internal electromagnetic field of SRG is analyzed by finite element method.Finally,the model of the wind turbine and SRG is established based on Matlab.The power characteristics of the wind turbine and the control methods of the maximum wind energy tracking are analyzed.A nonlinear simulation model of switched reluctance wind power generation system based on DC loads is set up.The simulation results show that the switched reluctance wind turbine meets the power supply of such load and the feasibility of the power generation system. |
