6 FAQs about [Composition of wind power synchronous generator]
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 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 different types of wind energy conversion technologies?
In the fields of renewable energy research, wind energy conversion technologies are gaining popularity. The squirrel cage induction generator (SCIG), doubly fed induction generator (DFIG), wound field synchronous generator (WFSG), and permanent magnet synchronous generator (PMSG) are the most often utilized generators with WECSs.
How do synchronous generators work?
When the rotor is driven by the wind turbine, a three-phase power is generated in the stator windings which are connected to the grid through transformers and power con‐verters. For fixed speed synchronous generators, the rotor speed must be kept at exactly the synchronous speed. Otherwise synchronism will be lost.
What are the components of a wind turbine system?
The system consists of a diode bridge rectifier, a DC-to-DC boost converter, a current-regulated voltage source inverter, a variable speed wind turbine, and a permanent magnet synchronous generator (PMSG).
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.
