Wind energy has an important significance for solving the world's energy and environmental issues , wind power has become the focus of the research of scholars from various countries . As more wind turbines field experiments necessary funds , long duration , it is necessary to construct a wind turbine characteristics in a laboratory simulation experiment platform , which is of great significance in promoting the research and development of wind power . This selection of the DC motor to simulate the wind turbine , torque - control method to simulate the speed - torque characteristics of the wind turbine . System modeling and simulation based on the Siemens DC speeder , and microcontroller constitute control hardware , the preparation of the control software , the DC motor simulation of wind turbine . The experimental results , simulation results and theoretical analysis show that the wind turbine simulation -based DC motor is correct and feasible , and has laid a good foundation for the follow-up study of the wind power generation system . The main work of this paper include : ( 1 ) from the aspects of the installed capacity , development status and technical characteristics made ??a more comprehensive overview of the status of wind power at home and abroad , and analysis of the operating characteristics of the wind turbine and wind turbine running area contrast kinds of wind turbine simulation program , and eventually established a DC motor torque of the wind turbine simulation program . Established components of the wind turbine simulator ( 2 ) Based on MATLAB simulation model , a comprehensive simulation study of the wind turbine simulator to verify the consistency of wind turbine simulator and the actual wind turbine mechanical properties as well as voltage feedforward excitation the compensation grid voltage fluctuation inhibition . ⑶ detailed analysis and design of wind turbine simulator hardware circuit . The correctness and feasibility of the software design general idea , given the flow chart of the main program and subroutine , the preparation of the C language source code , experimental results , simulation results and theoretical analysis to verify the simulation method .
