风力发电 MPPT sfunction 实现

该模型旨在鼓励学习者/学生发展带 PMSG 的变速风力涡轮机。 我考虑了基本参数在 Matlab Blocks 中，根据输出/负载几乎没有修改。 用户可以改变和模拟任何参数来研究系统。 用户可以为电池存储系统添加一个整流器和一个电池。

该系统中使用基于 2 质量模型的风力涡轮机为永磁同步发电机提供机械扭矩/输入。 该系统产生的三相电力，风速的变化也在该模型中呈现。

The output of the PMSG based wind energy conversion system (WECS) is fluctuating in nature due to intermittency of wind speed. The distribution static synchronous compensator (DSTATCOM) incorporated with the battery energy storage system (BESS) is used to smooth the power produced from wind generator system. The control strategy of BESS/DSTATCOM and its integration to mitigate the power fluctuations of grid connected WECS is presented. Three-leg three-phase voltage source converter (VSC) based DSTATCOM is used and the battery current is controlled to smooth the net power injected to the utility grid from wind power generation system. The control strategy implemented has the capability of supplying the required amount of power to the utility with help of batteries. The PQ control strategy is employed to control the three-phase inverter for managing power exchange with the utility grid. The real time wind speed data is considered for the simulation study of the system. The effectiveness of the control strategy of the system is validated through the simulation results in MATLAB/Simulink environment.

ABSTRACT —— Unbalanced grid voltage sags are the severe challenge for wind power generation system which connected to the grid successfully. The dc bus voltage and output power will fluctuate under unbalanced grid voltage. Moreover, the voltage sags will lead to the increase of peak current, which will bring potential safety hazards to the operation of wind power system. This paper proposes a simple current limiting control scheme without auxiliary equipment, which based on the detailed analysis of the excessive peak current. In this scheme, the machine side converter (MSC) controller adjusts the electromagnetic power according to the power transmitted to the grid by the grid side converter (GSC). Meanwhile, it converts the unbalanced power on the dc-link into the rotor kinetic energy, avoiding the dc-link overvoltage. The GSC controller can not only ensure that the three-phase inverter currents are in the maximum safe range that the converters can bear, but also provide reactive power support for the grid. Furthermore, the fluctuations on dc bus voltage and output power can be eliminated effectively by using the GSC controller. The feasibility of the proposed scheme and the superiority over the traditional control schemes have been verified by simulations under different types of unbalanced voltage.

虽然PMSG风机建模的文献很多，但我发现很难得到一个详细的simulink模型，所以我做了这个，希望你能充分利用它！

在技术论坛或一些网站中类似于mathwork，researchgate中找到的一些模型，有部分能用，部分没有参数文件，但是对于模型的学习与搭建应该有一定的帮助。
