Abstract
A mixer-ejector wind turbine uses an ultracapacitor system to store power from the variable generation of power by a permanent magnet generator. The system takes advantage of the MEWT area ratio, the higher velocity at the outer radius of the turbine, and the ability of the ultracapacitor system to store almost all of the input charge.
Claims21
A power generation system, comprising:
- a wind turbine, the turbine comprising:
- a mixer shroud enclosing a rotor/stator assembly, the mixer shroud comprising a ring of mixer lobes located along a downstream end and downstream of the rotor/stator assembly;
- the rotor/stator assembly including a rotor and a stator, the stator having a phase winding,
- the rotor having a central ring, an outer ring, a plurality of rotor blades extending between the central ring and the outer ring, and a plurality of permanent magnets on the outer ring;
- and
- an ultracapacitor bank electrically connected to the wind turbine.
The power generation system of claim 14, wherein the mixer shroud has an airfoil shape.
A ring generator for a wind turbine, comprising a stator surrounding a rotor;
- the stator having a phase winding,
- the rotor having a central ring, an outer ring, a plurality of rotor blades extending between the central ring and the outer ring, and a plurality of permanent magnets on the outer ring.
A process for producing energy, comprising:
- providing a wind turbine having a ring generator, wherein the ring generator comprises a stator surrounding a rotor;
- the stator having a phase winding,
- the rotor having a central ring, an outer ring, a plurality of rotor blades extending between the central ring and the outer ring, and a plurality of permanent magnets on the outer ring;
- placing the wind turbine having the ring generator in a fluid stream to generate energy;
- and
- collecting the energy in an ultracapacitor bank.
