Now I want to make a wind turbine model in order to charge a cell phone (i.e. to obtain a 5V1A DC re

If AC power is generated, it must be rectified to DC power and then stabilized with a constant voltage.

I think it is better not to charge cell phones with wind turbines, because the wind is unstable and charging is intermittent. Additionally, when used as a wind turbine, this motor will not reach 1,900 revolutions per minute. If you estimate the number of revolutions per second, the power can be very low.

Double-fed wind turbine models include third-order and fifth-order models. What does this command refer to?

Aerodynamic models are generally empirical models of aerodynamic forces. For wind power generation blades, the wind field around them is strongly affected by the wake of the upstream blades, so the aerodynamic forces they receive are generally unsteady and unstable. . Linear. Since the developmentCurrently, Computational Fluid Dynamics (CFD) is far from being able to directly solve the unstable aerodynamic force on the blade based on the N-S equation in real engineering, empirical aerodynamic models that guarantee a certain accuracy are very popular. Currently commonly used empirical aerodynamic models generally identify corresponding parameters based on wind tunnel test results. Commonly used aerodynamic models include the Beddoes-Leishman model, ONERA model, etc.

The simulink simulation model of wind turbines is. Generally, they all use torque as the input quantity, and the motor speed should be driven by the wheel speed.

In addition to the third and fifth order models, the unit to dual power supply also features an eighth-order model;

The 5th order model includes the stator model, rotor model and the simplified transmission. system model;

The 3rd order model It includes a rotor model and a simplified transmission system model, ignoring the stator transient process.

I also encountered this problem. When simulating a generator set, torque is usually used as the motor input. The output speed from the M end of the motor is fed back to the main motor. to adjust the main motor. The speed of both makes the speed of both consistent, but I think there is a logical problem with that. The speed and torque of the generator must be determined by the prime mover.

Maybe we can just reestablish the motor model and build a motor model with a mechanical shaft so that the mechanical shaft of the motor is coaxial with the main motorpal.
