Abstract

The already patented Madson Wind Turbine System (MWTS) embodies a wind turbine system for the collection of wind energy, compression of air (air or gas) in multi-stages to high pressure, for High Pressure—Compressed Air Energy Storage (HP-CAES), decompression of air in multi-stages, cooling of hot compressed air, harvesting of compression heat for heating cold decompressed air to increase volume & air flow for more efficient generation of electricity. This new invention constitutes a significant improvement of MWTS thru improved: ability to resist typhoons, cyclones & hurricanes, harvesting & directing hub area wind to the propellers, streamlining of wind for more efficient use by downstream wind turbines, harvesting of compression heat to heat decompressed cold air, simplification of equipment & construction by reducing the number of or combining the function of components, such as, the functions of transfer & regulator valves in previous inventions for lower capital & maintenance costs & greater efficiency; the introduction of new beneficial components, such as, uncloggable transfer valves; the avoidance of hazards, such as, bird strikes & nuisances, such as, flutter, pulse & vertigo and other improvements for the generation, storage and dispatch of electricity. This improvement also includes an HP-CAES Reserve Tank, constructed with Bolted Joints, such that it can be assembled quickly & cheaply without welding, de-stressing & spherical or thick plates; the elimination of, at least, one (1) built-in derrick and the development of self-regulating controls for feathering the propellers adapted to a Fan Wind Turbines instead of the conventional long aspect ratio sails (propellers).

Claims

1. This invention provides for aeronautic &

robust Fan Wind Turbines which can survive typhoons, cyclones &

hurricanes of up to 250 mpH (400 kpH) (strongest on record, not including tornados) by virtue of the aeronautic design, robust construction, low aspect ratio &

fully neutral featherability of propeller blades (FIGS. 1, 2, 3, 4, 5, 6, 14) and Guy Stays &

Guy Anchors (FIGS. 14, 15). This level of durability is not enjoyed by large capacity wind turbines with large aspect ratio sails (propellers) of the current state-of-the-art.

2. This invention provides an autonomous self-regulating control system by means of an elevator, which moves up &

down (in relation to wind speed) on the trailing edge of a horizontal fin to trim or fully feather propeller blades thru levers, tension bars, slide mechanism, rack &

pinion gears, bevel gears &

propeller discs (FIGS. 1, 2, 3, 4, 5, 6, 14), which are adapted to the control of the Propellers in a Fan Wind Turbine (FIGS. 3, 4, 5, 6)

3. This invention provides for Built-in Derricks for self-erection of the heavy components, such as, the propeller without the need for heavy construction cranes. Furthermore, all the heavy components present in the nacelles at the top of the current state-of-the art large wind turbines have been eliminated or moved to the base (FIGS. 1, 2, 3).

4. This invention provides for a square-cornered, concentric, catenary-sided HP-CAES Reserve Tank System with a Bolted Joint Tank design (FIGS. 7, 8, 9, 10), which makes possible the rapid &

economical construction of a manageably sized vessel capable of containing a sufficiently large volume of sufficiently high pressure air to store enough energy for grid or industrial applications in a manner that eliminates;

welding, stress relief, spherically dished plates or excessively thick tank walls. This invention needs only thin rolled steel plates (using only two dimension bending) which are easy &

economical to produce (not three dimensional dishing).

5. This invention provides for combining the functions of the Transfer Valves &

Regulator Valves used in previous MWTS inventions in order to drastically reduce the total number of valves, while maintaining all the benefits of both the Transfer Valves &

the Regulator Valves used previously. The new invention uses Transfer Valves alone with graduated weights to provide the pressure differentials between ring tanks while still allowing the extraction of inner tank high pressure air during periods of wind quiescence and without having Regulator Valves exposed to the outside.

6. This invention provides for Dispatch Valves (FIGS. 7, 8, 11), which may be Butterfly Valves, such that pressurized air may be released in seconds for the immediate dispatch of electric power.

7. This invention provides for an Underwater HP-CAES System which may receive high pressure air directly from the high pressure stages of the wind turbines into submerged vertical tubes at depths which utilize high water pressure to contain high air pressure, thereby, minimizing the structure needed to contain the high air pressure, while at the same time preserving the heat of the highly compressed air.
