摘要
针对研究对象直驱式永磁同步风力发电机进行了d-q坐标系下数学模型分析,主要包括风力机、永磁同步发电机、变流器数学模型的分析。从最大功率点跟踪原理出发,提出了风力机组网侧控制策略和发电机侧控制策略。在仿真软件MATLAB/Simulink下搭建了直驱风力发电机组的仿真模型;在正常和故障状态下对其进行仿真研究,并验证了控制策略的合理性和正确性。
The paper carries out the mathematical model analysis of direct driving permanent magnet synchronous wind generator on q-d coordinate system, mainly including wind turbine, permanent magnet synchronous generator and converter, and puts forward the control strategy for wind generators net side and generator side based on the maximum power point tracking principle. Finally, the paper builds a simulation model of the direct driving wind turbines with simulation software MATLAB/ Simulink, makes the simulation analysis of the model in normal operation and fault condition, and verifies the rationality and correctness of the control strategy.
