ENERGY AND EXERGY ANALYSES OF A WIND TURBINE BASED ON EXPERIMENTAL VALUES

摘要

Utilization of renewable energy resources for energy conservation, pollution prevention, resource efficiency and systems integration is very important for sustainable development. In this study we perform energy and exergy analyses of a wind turbine, located on the roof of Mechanical Engineering Department, King Saud University, Riyadh, Saudi Arabia. The turbine is part of a hybrid photovoltaic-wind system with hydrogen storage. The power output from this turbine ranges from 1.5 to 5.5 kW with a rated wind speed of 12 m/s and a cut-in wind speed of 2.4 m/s. We utilize a wide range of experimental data in the analysis and assessment. We determine energy and exergy efficiencies and sustainability indexes. We also undertake a parametric study to investigate the effect of meteorological variables on the exergetic efficiency of the wind turbine.
