摘要
为深入研究直驱永磁同步风力发电机组的高性能控制,研究了直驱永磁同步发电机侧系统构成、原理及建模方法,分析了风力机与永磁同步发电机、电压空间矢量(SVPWM)整流原理及其建模,基于双闭环PI控制搭建了机侧系统仿真模型。通过仿真与分析,证明了双闭环PI控制策略在4种不同风速下实现最大功率追踪的可行性。该系统模型的建立为机组高性能控制的研究打下基础,对于深入理解直驱永磁同步风力发电系统运行原理及推广应用具有重要意义。
To intensive study high performance control for direct-driven permanent magnet synchronous generator wind Energy systems,the structure,control principle and modelling of generator side systems were researched.The control principle and modelling of wind turbine,permanent magnet synchronous generator and space vector pulse width modulation rectifier were analyzed,and the simulation model of generator side control systems was established using double closed-loop PI control strategy.Through simulation and analysis,It is proved that the method for maximum power point tracking using double closed-loop PI control strategy under four different wind speeds is feasibility.The systems modelling is the basis for studying high performance control for wind energy systems.Moreover,it has significance meaning for knowing and applying control principle of Wind Energy Systems.
