| Studying and building a wind turbine simulation system and make it comparatively reflect the real condition of operation of a wind turbine, and providing a experiment environment for development of new technology in wind power are very necessary. By controlling inductive motor's electromagnetic torque, which is possible, it is nimble and rapid to simulate the mechanical transient. The paper separately studies the mathematical model of wind turbine and induction motor. For wind turbine, by analyzing the operation area of wind power system, max wind power tracking and pitch angle controlling basing on shaft rotating speed measuring are studied. For induction motor, vector control and space vector pulse width modulate are analyzed and selected separately as controlling algorithm and drive algorithm in simulation system. The simulation is proved feasible under matlab simulink. At last some basic job are done for building the physical simulating model. |
