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.)

说明： 编程计算图形的面积。程序可以计算圆形，长方形，正方形的面积，运行时先提示用户选择图形的类型，然后，对圆形要求用户输入半径值，对长方形要求用户输入长和宽的值，对正方形要求用户输入边长得值，计算出面积的值后将其显示出来。(Calculate the area of graphics programming. Program can calculate the round, rectangular, square area, run-time prompts the user to first select the type of graph, and then the radius of the circle requires the user to input the value of the rectangle requires the user to input the length and width values, requires the user to input side of the square grow the value to calculate the value of the area after the show.)
