Site-Dependent Wind Turbine Performance Index

Abstract

This letterpresents a method for estimating the dependence of turbine performance index on the specific site. The approach is based on the Weibull wind probability distribution function and manufacturer provided power curve. Instead of choosing a particular model for approximating the power curve, commonly usedpolynomial fitting is employed. A general approach to calculating the turbine performance index is derived, suitable for both fixed and variable speed wind turbines.
