Description

technical field [0001] The invention relates to an energy management system, in particular to an industrial energy diagnosis and analysis system and method. Background technique [0002] China is one of the largest energy consuming countries in the world, and energy costs account for a relatively high proportion of the total cost. Therefore, energy saving and consumption reduction have become the key tasks of various production enterprises in our country. Many large and medium-sized industrial enterprises have proposed a series of methods and measures to promote energy conservation and consumption reduction. Enterprise energy management is the basis of energy saving and consumption reduction work. Through the intuitive description of enterprise energy consumption, we can find out the weak links in the energy utilization process of these energy-consuming systems such as workshops or processes, and propose improvement directions and measures. [0003] The establishment of ene...

AI Technical Summary

Problems solved by technology

[0003] The establishment of energy consumption models in enterprise energy use analysis is usually based on mathematical models, such as system identification methods, etc., which are usually used for modeling individual energy consumption units of enterprises, and are developed for specific devices of enterprises, and the model has poor versatility

These modeling methods can reflect the production scale and energy consumption such as energy consumption cost analysis, input and output to a certain extent, but cannot reflect the energy consumption evaluation indicators for in-depth energy consumption analysis such as the system energy consumption structure.
