A method of assembling a wind electric power plant comprising the steps of:
- assembling a stub tower section which includes a drive shaft, an alternator, and an alternator armature shaft connected to the drive shaft;
- aligning the drive and alternator armature shafts;
- testing the assembled stub tower section in a test environment;
- moving the assembled stub tower in the assembled condition to an installation site;
- and
- placing the assembled stub tower onto an existing support at the installation site.
3 more elements
A wind electric power plant comprising:
- a stub tower section which includes tower corner rails, a gear section mounted on said corner rails, a propeller mounted on said gear section, a tail section mounted on said gear section, a drive shaft mounted on said gear section, an alternator mounted on said tower corner rails, an alternator armature shaft connecting said alternator to said drive shaft, and adjustment means connecting said alternator to said tower corner rails;
- said adjustment means including at least one wedge block interposed between said alternator and one of said tower corner rails and a wedge block moving means connected to said wedge block to change the position of said wedge block with respect to said one tower corner rail for changing the orientation of said alternator with respect to said tower corner rails and adjusting the orientation of said alternator with respect to said drive shaft so that said alternator armature shaft and said drive shaft are aligned to be coaxial with each other.
