The Research On System Of The Wind Turbine Wind Wheel

With the development of science and technology, Our country’s energy demand isshowing more and more urgent in the form. Traditional fossil energy is becoming less and less,and it also reflect its environmental pollution and ecological damage. Such as occurred recentlyin Beijing fog and haze, making it very clear just see the negative effects brought about by theuse of traditional fossil energy and unfavorable factors. Therefore, the use and development ofrenewable energy technology is becoming increasingly important. Continue to progress andbreakthroughs in renewable energy research. Most of mature and highest reliability in therenewable energy, wind power technology.To research and use wind power technology, first of all we are required to have a betterunderstanding of the wind turbine, wind turbine huge volume, less physical test. Therefore, wein the laboratory according to the principles and characteristics of the wind turbine windturbine model, and then build a wind wheel simulation test platform to simulate the windturbine and simulation test. This will not only effectively simulate the wind turbinecharacteristics, and can not spend a lot of money to the wind turbine on the actual operationtest. Thereby,completing the wind turbine in the laboratory.The first step is how the subject as close as possible to the actual effective establishmentof wind speed and wind turbine model. In wind speed model using several combinations ofwind, the wind speed model. The next step is a mathematical model of the wind turbine, andthen use the Matlab/Simulink simulation on the combination of wind speed and wind turbinecharacteristics, and collected from the actual wind farm wind speed wind turbine parametersobserved changes in wind speed curve and draw a graph comparing, thus proving thecorrectness and authenticity of the wind speed and the wind turbine model.Next is the design wind wheel simulator. With a variety of characteristics and conditionsof an asynchronous motor with an inverter to simulate the wind turbine. The importantparameters of the wind turbine, such as the speed of the wind turbine, and the torque and other important parameters, by constructing a wind turbine simulator can achieve good. Wind turbinesimulator is built by simulation and verify its correctness. After building control system toachieve the simulation of the wind wheel. Wherein the controller selects the DSP to DSPcontrol system to be simulated wind turbine inverter and the motor to be controlled in order toachieve their control parameter characteristic. DSP the bus communication forms and the lowerpart of the smart devices and instrumentation control box data interaction. Then through thehost computer and DSP communication man-machine interaction and communication. In thisway, we can be the entire control system from the host computer to send commands andobserve the parameters of the system, in the laboratory simulation of the characteristics of thewind turbine and a variety of conditions...
