| 20100060002 | WIND TURBINE DIRECT CURRENT CONTROL SYSTEM AND METHODS - A wind turbine control system converts AC power generated by the wind turbine to DC power for use in a load. The control system may include a plurality of modules that convert the AC power to DC power. The control system may include a turbine module that converts the AC power produced by a generator of the wind turbine to DC power. The turbine module may also include a boost converter that boosts the DC current to a higher voltage that improves efficient transfer of the DC power to the load. The control system may further include an output module having a buck converter that bucks the voltage of the DC power to a level needed for use by the load. The control system may control the amount of power generated by the wind turbine based on power needs of the load. | 03-11-2010 |
| 20100060001 | WIND TURBINE SAFETY SYSTEM AND METHODS - A wind turbine for extracting energy from the wind and providing electrical energy to a load. The wind turbine may include a rotor arranged to drive a generator, and an electronic controller for connecting the generator to an electrical load. The electronic controller operates to reduce the tip speed ratio of the turbine rotor as wind speed increases. The rotor is designed have a power coefficient at low values of tip speed ratios that becomes negative for wind speeds exceeding a predetermined wind speed value. The electronic controller cooperates with the turbine rotor such that the turbine rotor looses a positive power coefficient and the wind turbine slows when wind speeds exceed the predetermined wind speed value. | 03-11-2010 |
