matlab 下 sumulik对风力发电并网模型 (matlab under sumulik of wind power grid model)

说明：  压缩空气储能仿真simulink模型，适合matlab 2017及以上版本(model of CAES of simulink)

说明：  地球物理行业，在磁法勘探中 向上延拓Gui设计(Geophysical industry, extending GUI design upward in magnetic exploration)

说明：  bpa空载仿真程序用于单机运行仿真。包含了各种常用的类型(bpa swi file inclue all type of merchans)

异步电机速度、电流、磁链闭环控制，电流控制采取滞环控制，动态跟踪效果较好。(The closed-loop control of speed, current and flux of induction motor and hysteresis control of current control have good dynamic tracking effect.)

说明：  建立了风电场模型，可用于多情情况下的风力发电仿真(Established a wind farm model that can be used for wind power simulation in arousal situations)

根据历史数据，利用反馈神经网络对电力系统运行负荷进行预测(power prediction)

说明：  用拟牛顿法求非线性方程组 fi( x1, x2, ?, xn ) = 0, i = 1, 2, ?, n 的一组实数解。(A quasi-Newton method is used to find a set of real solutions of the nonlinear equations.)

说明：  分别对速度、磁场两个分量进行独立控制。通过控制转子磁链，以转子磁通定向，然后分解定子电流而获得转矩和磁场两个分量，经坐标变换，实现正交或解耦控制(The velocity and magnetic field components are controlled independently. By controlling the rotor flux, the rotor flux is oriented, and then the stator current is decomposed to obtain two components of the torque and magnetic field. Orthogonal or decoupling control is realized by coordinate transformation.)
