Embodiment

[0027] The ironmaking system mainly includes three parts: coking, sinter preparation, and blast furnace ironmaking. The main products of the first two processes, coke and sinter, are the main energy and raw materials for blast furnace ironmaking, supplemented by coal powder and raw ore. , pellets and other raw materials and energy, through the chemical reaction in the blast furnace, to obtain molten iron. According to the above process, the layered colored Petri net model of the ironmaking system is further established.

[0028] 1. According to the successive decomposition method, first establish a rough main Petri net for the ironmaking system, such as figure 1 As shown, it includes three major parts: coking T01, preparing sintering ore T02, and blast furnace ironmaking T03. Among them, the location identification and transition identification of each part are shown in Table 1 and Table 2.

[0029] Table 1 shows the places and their meanings in the built model

Abstract

The invention discloses an HCPN (Hierarchical Colored Petri Net)-based modeling method of an iron making system logistic energy consumption model. A petri net model of a huge complex iron making system is established by a method of detaching and combining the system through the HCPN. By the modeling method, the conventional modeling method of directly using the Petri net is optimized, the problem that the Petri net obtained by modeling and analyzing the complex system through the conventional Petri net is frequently unavailable is solved, and simultaneously, a better construction of the system model is provided, so that the analysis work can be executed in different construction stages, and the result of the analysis is guaranteed to be effective to the overall model. According to the method provided by the invention, based on the modeling and the simulation in the iron making process through the Petri net, the CPN (Colored Petri Net) model can be directly used in actual production dispatching control.

Description

technical field [0001] The invention belongs to the research field of logistics energy consumption modeling in iron and steel energy systems, and in particular relates to a method for modeling logistics energy consumption of iron and steel manufacturing systems by layered colored Petri nets. Based on hierarchical colored Petri nets, use optimization modeling tools to model the steelmaking process, clearly and intuitively describe the intricate energy process, Background technique [0002] In today's world, energy issues are the world's concern, and in our country, energy issues are increasingly becoming the focus of national life and even the whole society. Industrial enterprises, especially iron and steel enterprises are large energy consumers, and have become the top priority of energy conservation and consumption reduction. The energy-saving work of my country's iron and steel enterprises has also gone through several stages from energy-saving of single equipment to proc...
