The amount of electrical energy generated by each rotation of a wind power generator is also different. For example, the most common 2MW direct drive wind power generator can produce 2000 electrical energy every 60 minutes when wind power is low. sufficient and stable degree of electricity.
It takes 3.5 seconds for the fan blades to rotate once, and 60 minutes is 3,600 seconds. Therefore, the amount of electricity generated by the generator per second is 0.56 degrees, hence the amount of electricity generated by the generator. The wind power generator fan for each tower is The power generated is 0.56 × 3.5 seconds, or 1.94 kilowatt hours of electricity.
Detailed informationAs the wind volume is unstable, the wind turbine produces 13~25V alternating current, which needs to be rectified by the charger, and then charge the battery to producethe wind. power The electrical energy produced by the generator is converted into chemical energy. Then use an inverter with a protection circuit to convert the chemical energy of 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 via the gearbox and its high speed shaft to transmit torque to the drive shaft of the generator. This coupling must be. Has good damping and vibration absorption properties.
Performed by absorbing the appropriate amount of radial, axial and some angular deviations, and the coupling can prevent overloading of the mechanical device. The other type is direct drive fan blades which are directly connected to the motor without going through the gearbox. Type offan motor
