摘要
Abstract
Wind turbine simulator( WTS) is an important device for developing wind energy conversion systems. Its use makes the e-valuation and improvement of wind power generation technology in laboratory possible. A wind turbine model is built up through the research of the wind turbine characteristics. Then the indirect flux field oriented vector control strategy is studied. Because many de-fects exist in fixing speed sensor on induction motor, a speed-sensorless vector control scheme based on model reference adaptive system( MRAS) for wind turbine simulation of induction motor is proposed. Taking into account the impact of the rotor time constant on the vector control system, the paper simultaneously adopts identification rotor speed and time constant. The speed can be esti-mated accurately by the system, which system shows strong robustness to variation of motor parameters. At last, In MATLAB envi-ronment, the simulation system for wind turbine emulation based on speed-senseless control strategy of induction motor is designed. Through the simulation of wind turbine properties, maximal wind energy capture and the influence of parameter variation on vector control system,in indicates that the system is feasible.关键词
