  • Generally, there are the following three methods for grid connection of asynchronous wind turbines. (1) Directly connected to the grid. The conditions for direct grid connection of asynchronous wind turbines are as follows: ①The rotation of the generator rotor is consistent with the direction of the rotating magnetic field, that is, the phase sequence of […]

  • The control system of the wind turbine is an integrated control system. Take the grid-connected wind power generation system as an example. It monitors the grid, wind conditions, and operating data to control the grid-connected and disconnected wind turbines to ensure safety and reliability. Under this premise, the control system must not only optimize the […]

  • Since the rotation of the wind turbine is driven by the wind, it is not difficult to imagine that only when the wind blows vertically to the rotating surface of the wind wheel, the wind turbine can obtain the maximum rotational torque and output the maximum mechanical power. As we all know, the wind in […]

  • Normally, when the wind speed v>3m/s but not enough to drag the wind turbine to the cut-in speed, the wind turbine rotates freely and enters the standby state. In the standby state, except that the generator is not connected to the grid, the unit is actually in working state. At this time, the control system […]

  • There are very few applications of DC wind turbines. The most common models are constant-speed and constant-frequency squirrel-cage induction generators, variable-speed and constant-frequency doubly-fed induction generators, and variable-speed and variable-frequency direct-drive permanent magnet synchronous generators. 1. Constant speed and constant frequency squirrel cage induction generator Constant-speed constant frequency (CSCF) wind turbine is a generator that […]
