Study on dynamic prediction of surplus gas in iron-steel plant

This paper analyzes the advantages and disadvantages of mainstream prediction methods of gas system in iron-steel plant, proposes a set of general forecasting methods based on EMC (energy management center) for China's gas surplus in the current situation, establish a hybrid model which include the production and consumption mechanism of single device and the simulation of surplus gas. Application results show that: the method is suitable for different types of enterprises in varying construction degrees; model results can meet the data accuracy requirements; prediction analysis can be an early warning of instrument malfunction and system failure, also a scientific basis for buffer equipment purchases, production, and maintenance plan adjustment. © 2013 Springer-Verlag.
