The main difference is the wind power generation capacity. 3.0 is twice as much as 1.5 and can provide more electricity;
Therefore, regardless of the volume or internal components, the power level seems to be 2 times the relationship. Mainly Devices include;
Blades - with a large area, they can generate large torque under the action of the wind and do more work;
Generator - the blades convert wind energy into Mechanical energy drives the bearings of the generator to rotate, thereby using electromagnetic induction to generate corresponding electrical energy. Currently, there are two main types: permanent magnet motors and doubly-fed motors, which are suitable for full-power wind power and doubly-fed wind power respectively;
Converter --- converts the electricity with different frequencies from the generator into 50 Hz alternating current and inputs it into the power grid. In fact, it contains two power units, rectifier and inverter. Because the wind speed is unstable, the power generated The frequency of the electricity emitted is also not fixed (except for doubly-fed discharge machines).
Generators and converters are the two most critical components in wind power, and they are also the bottleneck of domestic wind power design.
