摘要：

The iron and steel industry, as a traditional user of high energy consumption, its load always shows has the characteristic of strong power fluctuation that generates the serious pollution to power grid. The production law of iron and steel industry is not considered in the previous researches of power systems. The fluctuation cannot be explained and the power fluctuation characteristic of iron and steel industry cannot be described. Therefore, the adaptability is poor in the problem research of small systems with the iron and steel industry. According to the impact of different severity, the loads in iron and steel industry are divided into continuous impact load, intermittent impact load and stable load. Firstly, considering the process control of production, three kinds of energy cunsumption behaviors are analyzed and the time domain model of power characteristics is established. Secondly, the time domain model of total power characteristics for iron and steel industry is obtained by adding up the models created above. Finally, the measured data of a large-scale iron and steel enterprise in China is taken as an example to verify the objectivity and accuracy of the model established in time domain and frequency domain. The relationship between the production and power fluctuation of iron and steel industry is revealed. © 2018 Automation of Electric Power Systems Press.
