Abstract
A mast is erected to support a load. At least one stay cable supports the mast. The stay cable has an end and an opposite end. The end of the stay cable attaches to an upper region of the mast. The opposite end of the stay cable anchors at earth. The stay cable is oriented at an angle not exceeding ten degrees.
Claims18
A wind energy installation, comprising:
- a mast;
- a rotor assembly supported by the mast, the rotor assembly having at least one blade, the rotor assembly rotating during wind;
- and
- a stay cable supporting the mast, the stay cable having an end attached to an upper region of the mast at a height greater than a tip of the at least one blade, and the stay cable extending uninterrupted along its length to an opposite end anchored to earth, the stay cable oriented to the mast at an angle having a maximum tangential value partially defined by a radial distance of the tip of the blade from the mast, the stay cable stressed to support the mast while the wind rotates the tip of the blade without collision of the stay cable.

A method, comprising:
- supporting a rotor assembly with mast;
- attaching an end of a stay cable to an attachment at an upper region of the mast at a height greater than a lowest point of a tip of a blade of the rotor assembly;
- anchoring an opposite end of the stay cable;
- orienting the stay cable to the mast at an angle having a maximum tangential value defined by a radial distance of the tip of the blade from the mast;
- and
- tensioning the stay cable to a stressed condition to support the mast while wind rotates the tip of the blade without collision of the stay cable.
