Abstract


Wind power as a clean, potential huge renewable energy, has a very important significance for the sustainable development of our country . China 's wind resources are very rich , and the development of wind power for some special region is promising . In China, especially for large - scale wind power policy support and market demand of MW -class power generation equipment , making large-scale wind power generation equipment in the country has been the rapid development and application . Essentially abroad MW class doubly-fed induction wind generator (DFIG) core technology previously monopolized by domestic manufacturers should not only pay premium prices , but also in the critical part of the control of others . The research topic through research double fed induction wind turbine works , the motor design principles and specific parameter calculation , combined with my many years experience in the production of motor development MW doubly fed induction wind turbines . The power emitted by the wind turbines to be incorporated into the working frequency of the power grid , very strict requirements for the control strategy . Doubly fed induction wind turbine with stator magnetic field oriented vector control strategy . The control mechanism of the doubly-fed generator , stability and harmonic components to establish a simple mathematical model analysis . Identify these conclusions can play a better role in guiding the design of the generator . Our air-to-air cooling of a 2MW doubly-fed generator prototype for instance , at the same time take full account of the structure of the user's requirements and the concept of humanity . Design and preliminary test data through its validation .
