Radial wind power generation equipment

Which machine is suitable for direct-drive wind power generation?

In this machine, voltage and frequency of the outer windings are controlled in accordance to speed of the rotor, which is dependent on wind speed. Hence, with the low-speed operation feature of magnetic-geared machines, this machine is particularly suitable for direct-drive wind power generation.

What are the topologies of electric machines for wind power generation?

Various novel topologies of electric machines for wind power generation have been developed. In , Beik and Schofield presented a hybrid excited machine, which combines wound field and PM rotor excitations, as shown in Figure 23 (a). This is a high-voltage generator with 6.87-kV RMS phase at 600 r/min.

What are the different types of wind turbine generation systems?

Two typical configurations of power electronic converter-based wind turbine generation systems have been widely adopted in modern wind power applications: type 3 wind generation systems with doubly fed induction generators (DFIGs) (Fig. 2a); and type 4 wind generation systems with permanent magnet synchronous generators (PMSGs) (Fig. 2b).

What is a wave-hydraulic wind turbine?

Schematic diagram of wave-hydraulic wind turbine . Combined with hydraulic energy storage system, Simpson proposed a new over-fixed wind turbine control method that allows the rotor to generate additional power beyond the rated power limit and store the additional power for later regeneration.

Are electric machines and drives suitable for wind power generation?

This paper has presented a comprehensive review of electric machines and drives for wind power generation in terms of challenges and opportunities. Compared to conventional electric machines for wind power generation, including SCIMs, WRIMs, DFIMs, and EESMs, PMSMs are regarded as the most promising candidate.

How does a wind power generation system work?

Traditional wind power generation technology uses a rotor to transmit wind energy to a gearbox and then to a generator to generate electricity [, , ]. The engine room is equipped with turbines, transmission systems, gear boxes and generators , which are very heavy, and the tower must have high strength .
