초록 ▼

Wind generator apparatus employs an induction generator with a wind-driven rotor. Connection of the induction generator to AC power lines is controlled by apparatus that compares generator rpm and line frequency. The rotor blades have a pretwisted, varying-chord inboard portion and an untwisted, constant-chord outboard portion. The blades are self-starting, operate efficiently over a range of wind speeds with constant pitch maintained by a torsional biasing mechanism, and pitch up automatically when the normal rpm operating range is exceeded. An improved blade-supporting spar of low torsional stiffness has an I-beam configuration with filament-wound flanges. A pitch damper prevents torsional oscillations while permitting the blades to pitch up readily. The rotor, which includes a teetering hub, is free to weather-vane about the axis of a supporting tower, but a yaw damper limits angular velocity. A guy wire and gin pole arrangement stabilizes the tower and permits easy raising and lowering of the tower.

대표청구항 ▼

In wind-driven generator apparatus, a rotor blade comprising an inboard portion and an outboard portion, the blade being shaped so that at rest the inboard portion has a substantial average pitch and the outboard portion has less average pitch than the inboard portion, the outboard portion being a substantially constant-chord portion and the inboard portion having a chord that increases as the root of the blade is approached.
