Research and Application on Energy Model and Energy Measurement Technology

The Dynamic multi-parameter online energy measurement technology is studied, and applied to establish a huge energy database after acquiring and storing the real-time enterprise energy consumption data of the energy sector, accurately and stably in working conditions. On the basis of the material balance and energy conservation principle, the mathematical model of the conversion process between production and energy and the model of the unit comprehensive energy consumption are established by the method of the energy consumption benchmark factor method and the e-p analysis. And production process and equipment energy consumption, unit energy consumption and product energy are evaluated and calculated as well. The models are used to the energy measurement and systems of a major brewery in Beijing successfully. Through the analysis and comparison of equipment and production process energy consumption, the system has directed production process optimization and energy-saving space assessment, and reasonably predicts the production process and equipment energy consumption.
