Abstract
A small horizontal axis wind turbine, with about a 2 kW power output
was constructed to convert wind energy into AC power to be fed into
the utility grid. The machine is intended to model operation of the
larger wind generators now being built. The variable pitch rotor is
18 ft in diameter and has a GA(W)-1 blade airfoil. The rotor is fabricated
from sitka spruce mounted on a commercial propeller/hub system.
Rotor speeds of from 75 to 150 rpm are used in operation. A chain drive
and helical gear drive system steps up rotor speed to 1800 - 3600 rpm to
drive a generator connected to the utility grid. The generator can be
operated in either an induction or synchronous mode; only the induction
mode has been used at the present time. Rotor speed, rotor pitch, turbine
azimuth, wind speed and direction, and power output are monitored
during·operation. Tower azimuth and rotor pitch are controlled during
experiments. An automatic data recording system is presently being installed.
A microprocessor automatic control system for adjusting azimuth
direction and rotor pitch will be installed shortly. A complete
set of experiments is planned for the spring of 1978.
