초록

A wind turbine blade made of a fixed blade section with an integral mounting flange for attachment to a wind turbine hub. A moveable blade section is attached to the fixed blade section and is free to move in a longitudinal direction relative to the fixed blade section. A positioning device controllably positions the moveable blade section to vary the overall length of the blade. This allows the wind turbine's rotor diameter to be adjusted. The rotor diameter can be increased in order to provide high power output in low wind conditions and it can be decr...

청구항

We claim: 1. A wind power generation system comprising: a turbine including a rotor having a plurality of blades which rotate about a substantially horizontal axis, wherein each of the blades has a separately variable length; a mechanism configured to separately vary the length of each of the blades; a controller configured to: control the mechanism that varies the length of each of the blades, and selectively alter the length of any number of the plurality of blades; and a sensor configured to measure inequalities in the balance of the rotor, and wher...
