Energy efficiency evaluation of wind turbine based on AHP

The energy efficiency level of wind turbines reflected its operation efficiency and provides evidence for the diagnosis. Currently, the evaluation study is concerned essentially with a part of Wind Turbine, but that has limitations. This paper establishes a synthetic evaluation index system of the energy efficiency evaluation of Wind Turbine from five respects, which include Comprehensive, profitability, power characteristics, equipment reliability, equipment consumption, and wind characteristics, which are base on actual operation. The accuracy of the evaluation results is determined by level of detail of the synthetic evaluation index system. The Analytic Hierarchy Process (AHP) was utilized to apportion weight of indicators, and the energy efficiency level of wind turbines were evaluated based on comprehensive fuzzy evaluation.
