Abstract

The aim of the current paper is to present an approach to a wind turbine selection based on an annual wind measurements. The proposed approach led to a choice of an optimal device for the given wind conditions. The research was conducted for two potential wind farm locations, situated on the north of Poland. The wind measurements pointed out a suitability of the considered localizations for a wind farm development. Six types of wind turbines were investigated in each localization. The power of the wind turbines were in the range of 2.0 to 2.5 MW and with a medium size of the rotor being in the range of 82 to 100 m. The purpose of the research was to indicate a wind turbine with the lowest sensitivity to the variation of wind speed and simultaneously being most effective energetically. The Weibull density distribution was used in the analyses for three values of a shape coefficients k. The energy efficiency of the considered turbines were also assessed. In terms of the hourly distribution of the particular wind speeds, the most effective wind turbines were those with a nominal power of 2 MW, whereas the least effective were those with the nominal power of 2.3–2.5 MW. The novelty of the proposed approach is to analyze the productivity for many types of wind turbines in order to select the one which is the most effective energy producer. The analyses conducted in the paper allowed to indicate a wind turbine which generates the highest amount of energy independently on the wind speed variation.

Summary

Introduction

Optimum usage of energy sources has become the priority for the majority of countries and regions. Considering that many countries have withdrawn from using raw fossil materials, the contribution of renewable energy generation forms will continue to grow stronger [1]. Research shows that the use of fossil fuels to obtain energy results in harmful air emissions, which impact global warming [2,3]. Authors of numerous forecasts state that the use of energy will continue to grow, and in the year 2050 it will reach a 50% higher level than the present one [4]. Production of energy based on fossil fuels will increase, but its growth will be considerably slower than the energy production from renewable sources
