Question

Maintenance of constant output at all wind speeds above rating is called _________

(a) Numeric rating scale

(b) Tenancy

(c) Flat Rating

(d) TRP

This question was posed to me during an internship interview.

The doubt is from Wind Turbine Operation topic in portion Wind Energy of Energy Engineering

Answer 1

Correct answer is (c) Flat Rating

To explain: More cost-effective design to a wind mill to produce rated power at less than the maximum prevailing wind velocity, using a smaller turbine and generator and to maintain a constant output at all wind speeds above rating. This is called flat rating.
