利用Ansoft软件和Matlab构建无线系统通用仿真平台(use Ansoft software and Matlab Construction General Wireless System Simulation Platform)

MATLAB模型，双馈风电机组基于最大功率跟踪，低风速超速控制，中风速高风速变桨距控制(DFIG MATLABThe wind turbine and the doubly-fed induction generator (WTDFIG) are shown in the figure called The Wind Turbine and the Doubly-Fed Induction Generator System. The AC/DC/AC converter is divided into two components: the rotor-side converter (Crotor) and the grid-side converter (Cgrid). Crotor and Cgrid are Voltage-Sourced Converters that use forced-commutated power electronic devices (IGBTs) to synthesize an AC voltage from a DC voltage source. A capacitor connected on the DC side acts as the DC voltage source. A coupling inductor L is used to connect Cgrid to the grid. The three-phase rotor winding is connected to Crotor by slip rings and brushes and the three-phase stator winding is directly connected to the grid. The power captured by the wind turbine is converted into electrical power by the induction generator and it is transmitted to the grid by the stator and the rotor windings.)

关于编程的一点小看法，值得好好品味一下哦(some ideas about coding)
