Synthesis optimizing and scheduling method of energy system

Abstract

The method comprises the following steps: firstly, field production energy flow data are input into a relational database through a manual input interface, or a real-time database collects the field production energy flow data transmitted by a production process control system and stores the data into the relational database; secondly, the scheduling personnel operates the information monitoring and scheduling function module, the data analysis function module through an operation interface, or triggers an event management function module through an external event, so as to read and write the relational database, or the scheduling personnel reads and writes the relational database through the operation interface or an management information system, transforms the data format of the read data, transmits the data to the operation interface for displaying or printing or to the management information system; thirdly, the scheduling personnel operates an energy optimizing function module and an energy planning function module to adopt the corresponding optimal scheduling for the production energy system according to the displayed or printed data and advice. The present invention can realize the global optimization of the enterprise energy scheduling.

Description

technical field [0001] The invention relates to an optimal scheduling method, in particular to a comprehensive optimal scheduling method for an energy system of a pulp and paper making enterprise. Background technique [0002] The paper industry is an important basic raw material industry that is closely related to the development of the national economy and social undertakings. According to statistics in 2004, the energy utilization rate of general large and medium-sized papermaking enterprises in my country is only 30%. The comprehensive energy consumption is as high as 2.5-3.0 tons of standard coal. The average water reuse rate of my country's paper industry is only 46%, and the average water consumption per ton of paper is as high as 100m 3 Above (world advanced level is only 10-20m 3 ), the fresh water consumption per 10,000 yuan of industrial output value is as high as 188 cubic meters. The high energy consumption of the papermaking industry not only leads to low ef...

Problems solved by technology

However, at present, my country needs to strengthen the research, development and application of energy optimization technology and energy-saving technology integration (including unit equipment energy-saving technology and system energy-saving technology integration) in the paper industry. The energy scheduling method of industrial production makes the automatic degree of energy scheduling of pulp and paper production seriously lag behind

In addition, due to the inability to obtain comprehensive production data, the existing energy dispatchers in the pulp and paper industry can only conduct dispatching based on a small amount of information and their own experience. Such an approach is neither scientific nor accurate, resulting in serious waste of energy consumption in industrial production , increasing the emission of pollutants from the enterprise

Many scientific research institutions have begun to focus on research in this area. Papermaking Science and Technology in Issue 06 of 2006 and Issue 02 of 2007 published the titles "Process Energy Synthesis Technology and Its Application in Energy System Optimization of Paper Industry". (I) - Theoretical basis of process energy synthesis model", "Process energy synthesis technology and its application research in paper industry energy system optimization (II) - Process energy synthesis method and model application in paper energy system" The article proposed to apply the "three links" energy system optimization method to the energy optimization of papermaking enterprises, and achieved preliminary results, but due to the lack of integrated methods and means, it has not been widely used in production
