Wind Energy Systems Flashcards
1
Q
How does site location relate to Wind Energy Systems?
A
Determines wind profile over the year - closest weather station is used.
2
Q
How does wind speed influence energy production?
A
Power is a function of windspeed, which varies based on height and location of a given turbine.
3
Q
Define power capacity per unit (kW).
A
Wind turbine rater power or capacity which is reached at the rated wind speed.
4
Q
Explain hub height.
A
Height at which the centre of the rotor is installed.
*Increasing hub height ususally improves project energy output.
5
Q
Define power curve data.
A
Provides the power output of a wind turbine as a function of wind speed.
6
Q
Define losses.
A
Airfoil losses and other miscellaneous losses.
