Upwind is the windward wind turbine, and downwind is the leeward wind turbine.
The difference between windward and leeward direction lies in the position of the wind rotor blades and wind turbine tower (relative to the direction of the incoming wind). The wind rotor is in front of the wind. tower, which is a wind turbine downwind, and the wind rotor is behind the tower. This is the downwind fan.
The two methods have different advantages and disadvantages. You can check out more information to learn more.
Since the speed of wind power is not constant, it is the same for dual-powered units and full-power units. It must therefore be rectified, then reversed and finally integrated into the network.
Rectification is a circuit that uses the unidirectional conductivity of diodes to convert positive and negative alternating voltages into unidirectional pulsed voltagesthey. Under the action of AC power, the rectifier diode turns on and off periodically, so that the load receives pulsating DC power.
After obtaining DC power, the inverter must obtain current with the same frequency and voltage as the power grid for grid connection.
