Analysis Model And Application Evaluation Of Energy Systems Based On Virtual Energy Theory

Energy,environment and sustainable development are the theme of the 21st century,and sustainable development is the center of three factors,energy and environment is the guarantee and foundation.The current energy analysis method is based on the laws of thermodynamics energy balance analysis,exergy analysis,and do not consider the impact of energy processes on the environment,which has certain limitations.This paper analyzes the energy balance analysis and exergy analysis,two methods are based on the first law of thermodynamics and the second law of thermodynamics established.This paper analyzes the advantages and disadvantages of these methods.In these theories,based on virtual energy theory and characteristics were studied.This paper put forward the calculation method of virtual energy input and output,established the energy analysis model of the system and equipment.According to the model electromechanical boiler efficiency and energy consumption of sewage treatment plants and Liaohe Oilfield Shuguang Gathering System were calculated.We discussed the impact of virtual energy on energy efficiency.The results show:The traditional energy analysis did not consider the environmental impact of exhaust and waste water discharge.The method based on virtual energy theory overcomes the disadvantages of this aspect.Analysis results are more objective and accurate.Virtual energy model can consider the environment and other factors,the model has a more realistic sense in the context of sustainable development.This article is the energy unit(equipment)and systems provide new ideas and new analysis methods.
