A Guide to Understanding the Most Common Types of Wind Turbine Generators

Once the turbine gains speed and connects to the generator, the wind pushes, but the magnetic field in the generator doesn''t let the generator rotor shaft turn any faster. Instead, power is produced according to how hard the wind pushes. The wind spins the turbine and in turn pushes against the rotating magnetic field of the generator.

6 FAQs about [Model and specifications of large wind knife generator]

What are the characteristics of a wind generator?

However, among the mentioned wind generator features, the torque density and energy efficiency are the two basic characteristics that are influenced by wind turbine dynamics and system architecture. Therefore, the selection of the electric generation system for wind energy demands special attention on these two characteristics. Table 2.

How to choose the best electric generator for wind power?

In fact, the choice of electric generator for wind power mainly depends on several criteria: structure, converter topology, environment (location where the turbine is installed), performances, and cost. Therefore, selecting the most appropriate electric generator for a wind power is a challenging task.
