Electric quantity consumption analysis method and system

Abstract

The invention discloses an electric quantity consumption analysis method and system. The method comprises: firstly, establishing an index library of electric quantity ton steel and unit time consumption; calculating the production ton steel consumption index of the current class; obtaining peak-valley-level membership degrees according to power consumption and power consumption peak-valley time periods per unit time of products of different steel types and / or specifications; calculating a peak-valley matching coefficient; and finally, analyzing the electric quantity consumption according to the production ton steel consumption index and the peak-valley coincidence coefficient. Fine analysis of the electric quantity consumption of the cold-rolled steel splitting specification is achieved, very important guiding significance is achieved for energy conservation, consumption reduction and cost reduction, and a powerful basis is provided for making electricity-saving measures and production plan scheduling.

Description

technical field [0001] The invention relates to the technical field of cold rolling, in particular to an analysis method and system for power consumption. Background technique [0002] As the country pays more and more attention to environmental protection and the competition in the iron and steel industry is increasingly fierce, energy saving, cost reduction and efficiency enhancement are the goals pursued by all cold rolling mills. Cold rolling mills (including continuous acid rolling, continuous annealing lines, hot-dip galvanizing lines, etc.) have a high degree of automation, complex process conditions, and are all continuous production lines. It is difficult to analyze the consumption level of products of different steel types and specifications. However, the consumption of electricity directly affects the production cost of the product. If the electricity consumption cannot be effectively controlled, it will inevitably lead to an increase in the production cost of the...

Problems solved by technology

Cold rolling mills (including acid tandem rolling, continuous annealing lines, hot-dip galvanizing lines, etc.) have a high degree of automation, complex process conditions, and are all continuous production lines, so it is difficult to analyze the consumption level of products of different steel types and specifications

However, the power consumption directly affects the production cost of the product. If the power consumption cannot be effectively controlled, it will inevitably lead to an increase in the production cost of the enterprise, which is not conducive to the profit of the enterprise and the competition in the industry.

The analysis of the actual consumption of specific steel types and specifications has not been refined, and the extensive management method of apportionment indicators and cost apportionment is not conducive to the accurate evaluation of order costs, nor does it play a practical role in supervising the production site personnel
