Working principle of wind energy inverter
Wind energy inverter is a device that converts wind energy into electrical energy. Its working principle is: the wind energy inverter converts the alternating current energy generated by the wind turbine into into DC power, and then converted into high-frequency AC power through a frequency converter, and finally converted into DC power through a rectifier, thereby achieving the purpose of converting wind energy into electrical energy.
A 200W wind turbine can also be used with a large battery and an inverter to obtain a power output of 500W or even 1000W or even greater. Is this true?
Can you answer it? Usually the input voltage of the inverter is 12V, 24V, 36V, 48V and there are other input voltage models, and the output voltage is generally 220V, which can be adapted to wind turbines. Wind turbines are electrical equipment that convert wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a director (tail), a tower, a speed limiting safety mechanism, and an energy storage device.
The nominal power does not represent the actual power that can be output.
Wind power generation is generally the electric energy (generally 3-phase AC) output by the generator when there is wind, which is then charged and stored in the battery. When electricity is used, the inverter inverts the DC electric energy stored in the battery. Convert to 220V AC and supply it to electrical appliances. The output power mainly depends on the power of the inverter and the capacity of the battery, and has no direct relationship with the power of the generator.
The selection of wind turbines should be based on the wind conditions at the installation site, and the batteries and inverters should also be selected within a reasonable range. For example, if the wind at the installation site is strong and the wind blows for a long time, a high-power generator and a large-capacity battery pack can be used. The inverter is selected according to the power of the electrical appliances. The bigger the battery, the better. If the battery is large, the motor is small or the wind is small, the battery cannot be fully charged. If it is in a state of power loss for a long time, the life of the device and the discharge time will be greatly shortened.
