Design Of Doubly-Fed Wind Turbine Simulation System Based On Matlab&Labview

Along with the development of wind power technology, the total installed capacity of wind power grows rapidly in China, and many large-scale wind farms have appeared in Inner Mongolia, Gansu, southeast coastal and other places of China. But, what is mismatch with the rapid development of wind power is the far short of the professional and technical personnel of wind power in our country, so the wind farm staff lack the work experience of wind farm operation and maintenance, and have difficulty in coping with the need of operating and maintaining the wind turbines, it seriously restricts the sustainable development of wind power. Therefore, it is particularly important to speed up the training of wind power technology talent.In order to meet the need of the training of wind power technology talent, a doubly-fed wind turbine simulation system based on Matlab&LabVIEW was designed in this paper. It can be applied in the preliminary training of wind farm staff, and students, etc.Firstly, the structure and operating principle of variable-speed constant-frequency doubly-fed induction generator (DFIG) which is divided into pneumatic system, mechanical system, electrical system, and pitching system, etc. was analyzed in this paper, and the mathematical model of all systems was established. In order to realize the training function of the simulation system, the bottom model was established based on Matlab, and the upper training function was realized based on Lab VIEW, that is:Establish the multiple physical model of DFIG with Matlab to realize the VSCF operation of DFIG and complete its bottom modeling; Design its operation interface to realize the synchronous exchanging of data between its interface and bottom model through the Simulation Interface Toolkit and lead the user to synchronously monitor the operation state of its bottom model; And then realize the Web publishing of its operation interface to make other clients remote access them through network and achieve its training function. On this basis, the designation of the structure of the simulation system was established, and the requirements about its hardware and software configuration were put forward in this paper.Finally, the simulation system was combined into operation, and the results showed the feasibility of the design scheme of the simulation system using Matlab and LabVIEW.
