Basic Principle of Wind Energy Conversion
In a nutshell, wind turbines use the rotation of the blades to generate electricity by turning a generator. The blades of a wind turbine are turned by the wind, which in turn spins a shaft attached to a generator.

6 FAQs about [Principle of wind power direct drive power generation]
What is direct-driven permanent magnet synchronous wind power generation system?
Direct-driven permanent magnet synchronous wind power generation system. Fig. 1.4 shows the double-fed wind power generation system. Both the stator and the rotor of the double-fed generator can supply power to the grid, in which the rotator is connected to the grid through a converter, while the stator is connected to the grid directly.
Are direct drive wind turbine generators better than geared generators?
A quantitative comparison of DFIGs, synchronous and PM generators is listed in Table 1. It can be seen that direct drive wind turbine generators are larger in size but shorter in length compared to geared counterparts.
How does wind power generation work?
The installation produces electricity by collecting and transforming wind power into rotational mechanical energy to drive a generating unit. Wind power generation technology is now relatively mature, with annual generation amounting to 640 TWh, accounting for less than 3% of the world’s total energy consumption.
What are the components of wind power generation system?
In terms of configuration, wind power generation system normally consists of wind turbine, generator, and grid interface converters where the generator is one of the core components. There are the following wind power generation technologies such as synchronous generator, induction generator, and doubly fed induction generator.
How does a wind turbine turn mechanical power into electricity?
This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity. A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade.
How does a geared wind turbine work?
In a geared wind turbine, the generator speed increases with the gear ratio so that the reduc‐tion in machine weight is offset by the gain in gearbox weight. For instance, the wind tur‐bine operates at a speed of 15 rpm and the generator is designed to operate 1200 rpm (for 60 Hz) .
