Wind turbine generator side conversion

What type of power converter is used in a wind turbine?

In wind turbines, dual voltage source voltage-controlled converters and voltage source current-controlled converters are being used. Two-fold PWM converters, which allow a bidirectional power flow between the wind turbine and the utility grid, can provide effective power control for specialized high-power wind turbines (Vasar et al., 2018).

How do wind power conversion systems work?

The implemented control systems for wind power conversion are divided into two parts: Control of the generator-side converter and control of the grid-side converter. Active power produced is controlled by the torque control with the orientation of the rotor flux providing a decoupling between these two quantities.

What are wind energy conversion technologies?

Wind energy conversion technologies are created in order to harness wind kinetic energy and transform it into mechanical power. Mechanical power can be converted to electrical power by using generators. This electrical energy is transferred to the grid or a free-standing load via a transformer and power converter (PC) for more general usage.

How can we improve wind energy conversion?

This principle of enhancing wind energy conversion should be met by ensuring the safety and integration of WECS technologies such as generators, power electronics converters, and grids. According to research reports [32, 33], WECS technologies have promisingly improved recently, and this has enabled to maximize wind power generation at fewer costs.

How do wind turbines work?

There exist two structures of wind turbines , ; the first structure operates at a fixed speed. It is directly connected to the electrical energy network. Whereas, the systems requiring power converters between generators and the grid. and permanent magnet synchronous generator (PMSG).

What is the difference between upwind and downwind turbines?

Upwind turbines—like the one shown here—face into the wind while downwind turbines face away. Most utility-scale land-based wind turbines are upwind turbines. The wind vane measures wind direction and communicates with the yaw drive to orient the turbine properly with respect to the wind.
