6 FAQs about [Asynchronous generator wind power]

How does a 3 phase asynchronous wind turbine generator work?

Figure 4 shows a full Simulink model of a three-phase asynchronous wind turbine generator. The Basic Turbine block uses a simple output power vs wind speed characteristic to translate wind speed to turbine output power. The machine creates no real power when the wind speed is below the cut-in speed or above the cutout speed.

Why do wind power plants use asynchronous generators?

The use of an asynchronous generator with a short-circuited rotor as part of a wind power plant is due to its high reliability, durability, maintainability and low cost, which directly affects the duration of operation of the autonomous power supply system, the cost of electricity generated and the cost of the wind power plant as a whole.

How does a synchronous wind turbine work?

With an excess of wind load, the synchronous machine operates in generator mode and accumulates electricity in the batteries, thereby providing additional braking torque on the wind turbine shaft and achieving stabilization of the rotation speed of the rotor of the asynchronous generator, as a result, voltage stabilization at its phases.

What are the parameters of a synchronous wind turbine?

Let us take the following parameters: the radius of the wind turbine is 2.3 meters, the stator current of the asynchronous generator varies from 0.4 to 2.4 amps, the wind speed is 4 m·s-1, the power of the synchronous machine is 0.4, 0.8 and 1.2 kW.

How much power does an asynchronous generator have?

For an asynchronous generator with a power of 1.1 kW, a synchronous machine with a power of 1.2 kW is adopted, which allows to stabilize the voltage on the stator of the asynchronous generator, when the wind speed changes from 0 to 25 m·s-1.

Which synchronous generator is best for wind power systems?

The permanent magnet synchronous generator seems to be the most adapted candidate for the wind power systems. In fact, this solution is a consensual one as illustrated by the evaluation summarized in Table 2 and based on the main characteristics of the wind power systems, each of them is graded from 1 to 5 points, where 5 points means the best.
