基于虚拟能的系统用能评价分析模型及应用

Energy Systems Analysis Model and Application Evaluation Based on Virtual Energy Theory

基于虚拟能理论,提出了单元(设备)和系统的用能分析模型,给出了系统输入端和输出端的虚拟能计算方法。根据所建模型,对污水处理厂能耗进行了分析计算,讨论了虚拟能对用能效率的影响。分析结果表明,传统的能量分析方法没有考虑废气、废水排放对环境的影响,基于虚拟能理论的用能分析模型克服了这个缺点,分析结果更加客观、准确。虚拟能分析模型考虑了环境等因素,在可持续发展的大环境下更具有现实意义。

Based on the theory of virtual energy, equipment and systems energy analysis model was built. The calculation method of virtual energy input and output was put forward. According to the model, sewage treatment plant energy consumption was analyzed and calculated. The impact of virtual energy on energy efficiency was discussed. The results show that the traditional energy analysis does not consider the impact of exhaust and wastewater discharge on the environment. The method based on virtual energy theory overcomes the disadvantage. 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.
