摘要： A method for operating a wind turbine having at least one blade includes determining an ambient air operating envelope and controlling a power output of the wind turbine at least partially based on the determined ambient air operating envelope. Determining an ambient air operating envelope includes measuring at least one of an ambient air temperature, an ambient air pressure, an ambient air humidity, and wind turbine power output. The method also includes comparing at least one of a measured ambient air temperature, a measured ambient air humidity and a measured ambient air pressure to predetermined ambient air temperature, pressure and humidity values. The method further includes referencing the predetermined ambient air temperature, pressure and humidity values to at least one operational parameter of the wind turbine. The method also includes determining if an existing wind turbine power output is within a range associated with the determined ambient air operating envelope.

摘要： A power generating system wherein a turbine (34) is mounted on top of a tower (30) or tethered underwater. The turbine (34) includes a rotor having a main blade (20) connected to a rotor hub (40) and an extender blade tip (22, 22′) attached to the main blade (20). During manufacture, the optimum energy-capture is determined using site-specific conditions of one or more of air density, wind speed, extreme wind, wind shear, noise and turbulence intensity. The extender blade tip (22, 22′) is chosen from a number of extender blade tips having a length that is the closest to the determined optimum energy-capture. The chosen extender blade tip is attached to the main blade either during manufacture or on-site. Alternatively, a one piece blade is produced based on information determined from the site specific conditions. The tip of such one piece blade can be customized based on the information obtained.

摘要： A method and apparatus for non-volatile overspeed protection is described. The present invention provides a method and apparatus for non-volatile overspeed detection to provide turbine rotational speed safety during a power outage. In one embodiment, aerodynamic braking is used to slow rotation of a rotor of the wind turbine. If an overspeed condition continues after application of aerodynamic braking, mechanical braking is used to reduce the rotational speed of the rotor. Power is supplied by a non-volatile power source to continue overspeed detection during a power outage. A low-pressure trigger valve is used to apply a mechanical brake when hydraulic pressure in the braking system falls below a predetermined threshold.
