The Power-control Of VSCF Wind Power Generation And Implement Of Experimental Platform

It is of great significance to develop and utilize wind power, which is not only renewable but also without pollution when energy source scarcity and environment pollution are getting more and more serious. The wind power generation technology has become the search hotspot of many country's scholars. The wind source of our country is plenty, which has big potential to be used.Firstly, this paper analyzes DFIG operation theory, a static equivalent circuit of DFIG is shown as well. Under the vector control strategy of stator field-orient, a vector control model will derive from the generator, which from a close control system with the generator model. In the simulation experiment, the referenced active & reactive power of DFIG model is found by the software Matlab/Simulink.On the aspect of hardware design, an experimental platform of VSCF doubly-fed wind power generation system was established, which takes the TI's DSP chip TMS320F2812 as its central controlling part. This paper discusses the design of the part circuit, analyzes EMI resources and approaches, and puts forward some effective hardware anti-interference methods. The experimental results testify the validity of the theory and show the stability of the experimental platform.
