WIND TURBINE |
摘要 |
<p>A system and method for fluid power conversion is described which can provide the basis for a new and improved wind turbine suitable to manufacture a horizontal axis (HAWT) or vertical axis (VAWT) turbine at one of a range of different power classes such as from 4kiloWatts to 10MegaWatts. In the case of the VAWT, the wind turbine comprises one or more turbine blades moving around a vertical axis wherein each blade is anchored to a central hub by at least one strut and by at least two cable wires. In the case of the HAWT, the wind turbine comprises two or more turbine blades moving around a horizontal axis wherein each blade is anchored to a central hub. The turbine central hub comprises a relatively large diameter, which is coupled to a power generation support structure via a plurality of roller bearings or the like. As the central hub turns, it drives the roller bearings, which are each coupled with a separate power generation component such as an electric generator or a hydraulic gearpump. This configuration of a large diameter central hub coupled to multiple electrical power generators and or gearpumps wherein each power generation component of the system is controlled by an intelligent central system controller, provides versatile control of the net output power generated by the turbine and thereby maximizes the efficiency of the turbine over a range of wind speeds. The electric generators and or hydraulic gearpumps may together comprise a range of power conversion ratings to further optimise and control the power output of the wind turbine over a range of wind speeds.</p> |
