ABSTRACT:
A more efficient wind power generation system is afforded by extending tower heights to several hundred meters to operate wind catching rotors and generators aligned with the wind direction at various levels along the tower. With multiple vertically cascaded wind generators and higher velocity winds at higher elevations greater power is produced in a system characterized by a small footprint. This is particularly enhanced by a single mast construction, which is supported by a dynamic guy wire tensioning system to accomodate varying lateral forces primarily caused by the change in direction of wind loads on the tower. The mast is built from modular sections connected together at articulated joints, between which the various rotors are stationed. Thus, the accumulated torques and lateral stresses in the tower are minimized and do not accumulate along the length of the tower thereby to lengthen life expectation and reduce the chances for catastrophic failure in the presence of the higher velocity winds encountered. Also maintenance at such heights necessary where movable parts are present, is enhanced by an internal lift in the mast structure and an uppermost work platform with a rotatable lifting crane.
