1.	Why severe fluctuations in power are always undesirable in windmill?(a) Because they pose power oscillations problems(b) Damage of parts due to fluctuations(c) The efficiency of the plant will be reduced(d) Results in damage to the whole plantI got this question in final exam.I want to ask this question from Wind Turbine Operation in section Wind Energy of Energy Engineering
Answer» Right answer is (a) Because they pose POWER oscillations problems To explain: Severe fluctuations in power are always undesirable, because they pose power oscillation problems on the grid and severe strains on the windmill hardware. From an economic point of view, a windmill is designed to produce a rated power output corresponding to MAXIMUM, or near maximum, PREVAILING WIND velocity at a given site would generate low powers, with full capacity of the turbine and electric generator unused much oftime.
