Research On Energy Efficiency Difference Analysis And Optimization Path Of Thermal Power Plant

Power is an important component of China's power structure,and it is also an important energy base of China's economy.It provides strong support for social progress and economic development of our country,but it is also an important source of increasingly serious environmental problems.In China,coal for power generation is accounted for more than 50% of industrial coal consumption.Coal consumption for power generation is reduced year by year,which reaches the world advanced level,but compared with the developed countries in Europe,the United States and Japan,there is still great space to improve.With the national emphasis on energy-saving and environmental protection,thermal power plant is put forward higher requirements on the energy efficiency optimization,which is as an large place of primary energy consumption and pollutant emissions.It is the starting point of energy-saving research that power generation enterprises to achieve high efficiency and low emissions on the basis of provide power guarantee for national economic development.Therefore,in order to reduce the impact of thermal power generation on the economic environment,this paper studies the related issues of energy efficiency of China's thermal power enterprises.Firstly,the difference of energy efficiency among regional thermal power enterprises is analyzed.In this paper,we construct the input and output index system of total factor energy efficiency,and establish the total factor energy efficiency analysis model based on data envelopment analysis,and acquisition related indicators of thermal power enterprises in China's region.The total factor energy efficiency is calculated,and the differences between regions are analyzed.Secondly,the energy efficiency optimization path analysis model of thermal power enterprise based on AIM/enduse model is established.Based on the analysis of the production technical process of thermal power enterprises in China,we set up the simple framework of thermal power enterprises,and set the parameters of the model in this paper.The energy consumption,overall CO₂ emissions and energy efficiency of thermal power enterprise are measured in the three scenarios of energy efficiency,structure and energy conservation,and the energy conservation is determined as the main way of the energy efficiency optimization path.Finally,the optimal technology selection model of thermal power enterprise based on the system dynamics model is established.In this paper,we build the energy efficiency calculation flow chart of thermal power enterprise,and take the related data of Guodian Datong second power plant as an example for empirical analysis.The effect of optimization technology is analyzed,and the most suitable technology for optimization is determined.This paper has some significant reference to enhance the energy efficiency of thermal power enterprises.
