The amount of electric energy generated by each rotation of a wind energy generator is also different. For example, the most common 2MW direct-drive wind energy generator can produce 2,000 electric energy every 60 minutes when the wind energy is sufficient and stable. degree of electricity.
It takes 3.5 seconds for the fan blades to rotate once, and 60 minutes is 3600 seconds. Therefore, the amount of electricity generated by the generator per second is 0.56 degrees, so the amount of electricity generated by the wind energy generator fan for each revolution is The power generated is 0.56×3.5 seconds, which is 1.94 kilowatt-hours of electricity.
Extended informationBecause the wind volume is unstable, the wind turbine outputs alternating current of 13~25V, which must be rectified by the charger and then charge the battery to make the wind power The electrical energy produced by the generator is converted into chemical energy. Then use an inverter power supply with a protection circuit to convert the chemical energy in the battery into AC 220V mains power to ensure stable use.
Mechanical connection and power transmission: The horizontal axis fan blades are connected to the universal elastic coupling through the gearbox and its high-speed shaft to transmit the torque to the drive shaft of the generator. This coupling should be Has good damping and vibration absorption properties.
Performed by absorbing the appropriate amount of radial, axial and certain angular deflections, and the coupling can prevent the overload of the mechanical device. The other type is the direct-drive fan blades that are directly connected to the motor without passing through the gearbox. Type of fan motor
