Abstract

The commonly used two-dimensional power calculation method tends to over-estimate power generation in complex terrains. A three-dimensional power calculation function is formulated so as to provide more accurate estimation function as below. P0 ,PRate, α, and γ are power in power curve, rated power, tilt angle, and wind inclination respectively. P=min{PRate(cos(gamma;+α)/ cosγ·cosα)3·P0} It was verified through a field test of SUBARU22/100, 100kW wind turbine. Furthermore, simulations were carried out on a typical wind farm in complex terrain. AEPs were compared between the existing two-dimensional and the present three-dimensional calculation methods. The former was shown to estimated 6% more AEP than the latter one in the case. The present achievement provides more accurate power calculation method in complex terrains.
