Wind turbine rank method for a wind park scenario

Abstract

Purpose This paper aims to present a method of the wind turbine ranking, either stall or pitch-regulated wind turbine (WTG), to determine the suitability of wind turbine in a selected site. Design/methodology/approach The method included the wind park target capacity, the maximum hub-height, the standard rotor diameter and the characteristic of wind speed on the site. As the method had been applied to a wind park, with more than one wind turbine, the wake losses had been considered by subtracting the gross capacity factor. Besides, the turbine-site matching index (TSMI) was computed by dividing the net capacity factor with the total installed capital cost per kilowatt. Findings The components of the total installed capital cost were cost of turbine, installation, as well as operation and maintenance. Meanwhile, the target capacity index (TCI) was calculated by dividing the estimated wind park capacity with the target wind park capacity. Originality/value Both TSMI and TCI were used together to rank the wind turbines. Furthermore, a site in the eastern part of Kudat was selected as the case study site, where ten models of wind turbines were tested and ranked.
