electrical power P/PN, Rayleigh distribution h(v) und
power coefficient cp over wind speed v
© 2002 by Volker Quaschning
  Annotations
The Rayleigh distribution is h(v) = p/2 * v / (vm2) * exp ( -p/4 * (v/vm)2 )
The power coefficient cp is given by cp = 2 * Pel / (r * Arotor * v3)
The mean power is calculated with Pm = hfield * hV * Si ( P(vi) * h(vi) )
The annual output is calculated with Ea = Pm * 8760 h
The full load hours are given by hfull load = Pm / PN * 8760 h

Detailed information about calculation and simulation of wind energy converters you will find in the specialists book Understanding Renewable Energy Systems.

Attention: This performance analysis is only a rough estimation that can not replace a detailed planning and analysis. No responsibility is accepted for the correctness of this information.
