摘要
在Simulink/Matlab环境下建立风力发电系统仿真模型。针对经典的基于爬山搜寻控制的最大功率点跟踪(MPPT),提出了一种新的改进型MPPT控制策略,采用风速湍流作为搜寻信号,进而实施最大功率点跟踪控制。仿真结果表明:这种改进型控制策略可以有效地提高风能转换系统的效率和质量,能够很好地实现风力发电机最大功率点跟踪控制。
A wind power system simulation model is established in the Matlab/Simulink environment. According to the classic maximum power point tracking （MPPT） which is controlled by climbing search, this paper puts forward a new improved MPPT control strategy by using wind turbulence as search signaling, and thus implements the maximum power point tracking control. Simulation results show that the improved control strategy can effectively improve the efficiency anti quality of wind energy conversion systems, and can perfectly realize the maximum power point tracking control of wind turbine.
