Based On The Dc Motor Characteristics Of Wind Turbine Simulation Test Platform

Doing the experiment at the field of wind power generation, which could obtain the exact and direct laboratory result. However, because of the bad environment in the wind power generation field,the narrow experiment's space, the process of experiment can't achieve, if this happens then, not only we need to increase the research funds and time, but also use up a large numbers of manpower and material resources. Therefore, constructing the experimental platform of wind turbine simulator, which is the key of researching the wind power generation system, means great significance to us in driving our wind power generation continuously expanding.Firstly, this paper introduced the exploiture of wind energy resource and the adjustment control technology of wind power generation system, the paper introduced the operation characteristics of wind turbine and the principle of optimal capture of wind energy, and presented the control method that the characteristics of DC motor can be converted into wind turbine. Discussed the running state of wind turbine under various kinds of working condition, the feasibility to imitate the performance characteristic of wind turbines by using a DC motor has been testified, by the simulation and experiment. The DC-DC buck converter controlled by DSP (digital signal processor) regulates the DC voltage to control the speed of the DC motor, so that can imitate the performance characteristic of wind turbines. A program was introduced that made the DSP control the DC motor to imitate the performance characteristic of wind turbines. The paper introduced the CCS (Code Composer Studio) of DSP's integrated development environment, gave the method of PWM waveform generation and concrete-implement of software. The laboratory results show that wind turbines could run to follow the mechanism of maximum wind energy in the different of the wind speed module, and could quickly enter steady running state, which got the well control effect. The paper supplied a method for imitating the performance characteristic of wind turbines in the laboratory condition and the possibility of researching wind power in the laboratory.
