摘要
为有效提高电气控制类专业学生科研创新素养,利用Matlab/Simulink数值仿真平台建立双馈感应发电机并网运行仿真实验。采用定子电压定向的转子侧和电网侧变换器模糊PI矢量控制策略,针对电网电压小幅跌落状态下,研究定子、转子电流动态过程、功率波动以及直流母线电压变化。仿真结果和理论分析一致,验证了所建仿真实验的正确性。通过实验教学,强化理论教学效果的同时,有助于培养学生利用仿真技术解决科研问题的思维,增强学生的创新创造能力。
In order to effectively improve the scientific research and innovation literacy for students majoring in electrical control,based on Matlab/Simulink numerical simulation platform,a simulation experiment of grid connected operation for doubly fed wind turbine is established.The fuzzy PI vector control strategy for rotor side and grid side converter with stator voltage orientated is adopted.The current fluctuation of stator,rotor and power,and the voltage fluctuation of DC bus capacitor under the condition of small voltage dip are studied.The simulation results are consistent with the theoretical derivation,which verifies the correctness of the simulation experiment.Through this experiment teaching,the students’understanding of the contents for many courses they have learned is further deepened.It not only strengthens the theoretical teaching effect,but also helps to train students’thinking of solving scientific research problems by using simulation technology,which enhances students’innovation and creativity.
