Comprehensive Evaluation of Energy Saving and Emission Reducing Performances of Thermal Power Enterprises Based on the Entire-Array-Polygon Indictor Model

Effectiveness of thermal energy saving and pollutant reducing determines the overall goals of Chinese energy saving and pollutant reducing policy. Based on the requirements of relevant national policies, a comprehensive index system of thermal energy saving and pollutant reducing is established from energy resource consumption, resource utilization, pollutant emissions and business efficiency.In this paper, a method based on the entire-array-polygon indictor evaluation model is developed to evaluate the performance dynamically,which can overcome the influences of subjective factors. In final section of this paper, taking a thermal power plant as an example, an evaluation on its energy saving and pollutants reduction effect is performed. The result shows that the overall performance of this plant's energy reduction index is upward with seasonal fluctuations and the performance of the technological transformation projects is effective.The evaluation method is feasible.
