Abstract
In this paper, evaluation index system with two levels is established to evaluate energy efficiency of fossil-fuel power plant in a comprehensive and objective way, in order to provide detailed methods for energy-saving and emission reduction. The index system includes five indicators at the first level and two indicators at the second level. Principal component analysis (PCA) model is adopted to comprehensively evaluate energy efficiency of fossil-fuel power units. PCA is a relatively objective evaluation method, which can not only determine weights objectively, but also roundly reflect most information from multiple indicators. The method presented in this paper is implemented on seventeen 1000MW thermal power units. The results obtained agree well with the actual situation and those in the references.
