小型风力发电提水系统设计

文章提出将风力发电并网与提水技术结合,研究了小型风力发电提水并网系统的仿真设计,将风电机组发出的电能并入电网,同时驱动水泵运行。根据坐标变换理论,搭建了风力机、永磁同步电机、PWM变流器以及水泵机组的数学模型,通过选取合适的控制策略,达到实现风能最大功率跟踪、水泵稳定运行以及并网有效性的目的。最后通过Matlab/Simulink软件对设计的系统进行仿真,验证了上述建模及控制方法的可行性。

This paper proposes the combination of wind power grid and water lifting technology,and studies the simulation design of small wind power grid water lifting system.The electricity generated by wind power unit is incorporated into the power grid and the water pump is driven at the same time.According to the coordinate transformation theory,the mathematical models of wind turbine,permanent magnet synchronous motor,PWM converter and water pump are built.By selecting the ap-propriate control strategy,the maximum power tracking of wind energy,the stable operation of water pump and the effective-ness of grid-connection are achieved.Finally,the simulation of the designed system is carried out through Matlab/Simulink soft-ware to verify the feasibility of the above modeling and controlling methods.
