Doubly fed induction generator (DFIG) wind turbine controlled

The main goal of this paper is to show the control capabilities of artificial organic networks when they are applied to variable speed wind generators. Since doubly fed induction

Synchronous Generator as a Wind Power Generator

Synchronous Generator Synchronous Generator as a Wind Power Generator. Like the DC generator in the previous tutorial, the operation of a Synchronous Generator is also based on Faraday''s law of electromagnetic induction,

Introduction to Doubly-Fed Induction Generator for Wind Power

An AC-DC-AC converter is included in the induction generator rotor circuit. The power electronic converters need only be rated to ha ndle a fraction of the total power the rotor power typically

The difference between asynchronous and synchronous generator

Introduction Most wind turbines in the world use a so-called three phase asynchronous (cage wound) generator, also called an induction generator to generate alternating current.This type

why induction generator is used in wind turbines

The main function of a wind turbine generator is to transform the kinetic energy captured by the wind turbine blades into electrical energy. Reasons why induction generators are used in wind turbines Asynchronous

6 FAQs about [Asynchronous generator for 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.

How much power does an asynchronous wind turbine produce?

As the asynchronous machine operates in generator mode, its speed is slightly above the synchronous speed (1.011 pu). According to turbine characteristics, for a 10 m/s wind speed, the turbine output power is 0.75 pu (206 kW). Because of the asynchronous machine losses, the wind turbine produces 200 kW.

What is an example of a synchronous generator?

For the example, the wind speed (10m/s) is such that the wind turbine produces enough power to supply the load. The diesel generator (not simulated) is stopped and the synchronous machine operates as a synchronous condenser with its mechanical power input (Pm) set at zero.

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.

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.

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.
