Outdoor wind turbine generator transformation

How has technology changed wind power generators?

Meanwhile, the rapid development of power electronics technology has enabled a technological transformation in wind power generators over the past three decades (for example, from fixed-speed low-power wind turbine generators to variable-speed high-power wind turbine generators) 17, 19, 29.

What is a wind energy conversion system?

A wind energy conversion system (WECS), converts the kinetic energy of the wind into mechanical power. In the next step, mechanical power is used to rotate generators in order to produce electrical energy. Wind turbines, electric generators, control systems, and power electronic interface devices are the four main components of the WECS.

How does a wind turbine work?

In modern wind turbines, wind rotates the rotor blades, which convert kinetic energy into rotational energy. This rotational energy is transferred by a shaft which to the generator, thereby producing electrical energy. Wind power has grown rapidly since 2000, driven by R&D, supportive policies and falling costs.

Do generator enhancements impact all turbine-based energy conversion systems?

Generator enhancements impact on all turbine-based energy conversion systems. Crucial research gaps are identified to guide future research directions. The deployments of on-shore and off-shore wind turbines have been found to be one of the most feasible methods to promote renewable energy generation in today’s modern era.

Do wind turbine generators increase power ratings?

The main focus of wind energy related industries is to identity efficient yet reliable solutions to lower the cost of energy conversions . In recent years, the advancements and enhancements of wind turbine generators managed to increase the power ratings . However, there are a few points to look out for.

Do DFIG-based wind turbines have a combined vector and direct power control?
