Question

A wind turbine designed too to come into operation at a minimum wind speed is called _________

(a) Cut in velocity

(b) Windward

(c) Cut out velocity

(d) Upwind location

The question was asked at a job interview.

This interesting question is from Wind Turbine Operation topic in section Wind Energy of Energy Engineering

Answer 1

The correct option is (a) Cut in velocity

Best explanation: Due to several loss in efficiency and power at low wind velocities, a wind turbine is designed to come into operation at a minimum wind speed called the cut in velocity. Thus the wind turbine operates with variable load over a narrow range between cut in.
