Embodiment example

[0038] Implementation case: The production optimization link of the modeling system includes diaphragm electrolysis of salt water, the combination of chlorine and hydrogen to produce hydrochloric acid, the sodium method to produce bleaching powder and the ethylene oxychlorination method to produce vinyl chloride. There are three main raw materials: raw salt, lime slurry, and ethylene. Six products are produced, namely chlorine, hydrogen, caustic soda, hydrochloric acid, bleaching powder and vinyl chloride. Among them, chlorine is used as the raw material for the production of vinyl chloride, hydrogen and chlorine are used as the raw materials for the production of hydrochloric acid, and chlorine and caustic soda are the products of bleaching powder. Raw materials. Mainly consume three kinds of energy: water, electricity, steam, see figure 2 . Scheduling period T P =120 hours, see Table 1 for the scheduling plan. See the water consumption of the electrolyzer Figure 5 .

Abstract

The invention provides an optimization modeling method for coupling of production and energy of continuous enterprises. The method comprises the following steps: establishing a CEECOM unit model X; setting an information parameter of a CEECOM production dispatch velocity model psi to generate a CEECOM system model; determining the material type and listing a constraint equation according to the Petri network topology structure of the CEECOM system model; and running a simulation algorithm to calculate energy consumption and generate a corresponding curve. The method adopts a color expansion blending Petri network method, and gives consideration to energy flow, material flow and information flow. The modeling method of the invention has strict theoretical foundation, is concise, convenient and easy, and is suitable for practical use. The method realizes reoccurrence of energy consumption process of enterprise production by acquiring data from a DCS or database. Safety pre-warning is provided regarding unsafe information parameter of energy consumption equipment (unit) in enterprise production energy consuming activities, and the control model implements corresponding processing if a corresponding measurement cannot be obtained within the safety pre-warning time. The method can be jointed with an ERP so as to realize dynamic simulation in the enterprise production energy consuming process.

Description

Technical field [0001] The invention belongs to the field of information technology, and relates to an enterprise energy system modeling method, in particular to a continuous enterprise production and energy coupling optimization modeling method. Background technique [0002] Industry is a major energy consumer in my country, and energy consumption accounts for about 70% of the country’s total energy consumption. High-energy-consuming enterprises in key energy-consuming industries are also major industrial energy consumers. High-energy-consuming enterprises are continuous enterprises such as petroleum, petrochemical, coal chemical, and chemical industries. The high energy consumption of the enterprise is determined by the process route and production characteristics. Therefore, with continuous enterprises as the main body of energy conservation and consumption reduction, the establishment of enterprise energy models is effective for improving enterprise energy conservation managem...
