Enterprise energy efficiency management system and management and control method therefor

Abstract

The invention discloses an enterprise energy efficiency management system and a management and control method therefor, and belongs to the field of energy management. The system comprises an information collection unit, an information processing unit, a control unit, and an operation unit. The information collection unit, the information processing unit, the control unit and the operation unit are sequentially connected. The information collection unit comprises an information automatic collection module and a communication module, wherein the information automatic collection module is connected with a computer DCS system of the operation unit through the communication unit. The information processing unit comprises a data calculation module, a data comparison module and a data analysis module. The control unit comprises a factory-level scheduling command system module, a production plan cost check module, an equipment energy consumption economical efficiency diagnosis module and an equipment state diagnosis module. The system can find hidden or exposed various problems, which affect the high-efficiency utilization of energy sources, at the links of enterprise resource production, conveying, transfer, distribution and consumption in a thermodynamic system, can carry out the diagnosis and analysis of the problems and provides processing suggestions.

Description

technical field [0001] The invention relates to a management system, in particular to an enterprise energy efficiency management system and a management and control method for monitoring the energy utilization efficiency and effect of various links such as energy production, transmission, conversion, distribution and consumption in metallurgical enterprises. Background technique [0002] At present, there are many deficiencies in the maintenance work of metallurgical enterprises in terms of economic operation and equipment maintenance, which are manifested in the following aspects: [0003] (1) Production dispatching and commanding: The current dispatching and commanding system mainly conducts command and gives orders based on experience. Even experienced people cannot achieve scientific, reasonable and precise commanding; If you make a problem, you will inevitably be at a loss, and it is difficult to issue correct instructions. [0004] (2) Production planning and cost acc...

AI Technical Summary

Problems solved by technology

[0003] (1) Production dispatching and commanding: The current dispatching and commanding system mainly conducts command and gives orders based on experience. Even experienced people cannot achieve scientific, reasonable and precise commanding; If you make a problem, you will inevitably be at a loss, and it is difficult to issue correct instructions

[0004] (2) Production planning and cost accounting: The current production plan is formed by apportioning tasks assigned by the superior department in the same period of the previous year and this year to each month. However, in actual production, the current equipment operation situation is different from that in the same period of the previous year. In the same way, the tasks assigned by the superior department cannot fully match the existing equipment capacity, resulting in a disconnection between the production plan and the actual situation

[0005] (3) Diagnosis of equipment energy consumption: there are many types of equipment in the enterprise, and the horizontal comparison of equipment energy consumption between different types of equipment cannot be carried out. Therefore, it is necessary to diagnose the economic situation of a single equipment. However, the calculation process of energy consumption It is cumbersome, and the calculation requires a high level of technology, rich work experience and a long time to complete. By the time the calculation is completed, the tasks and conditions of production may have undergone major changes, and the calculation results cannot be used for immediate guidance. Production

[0006] (4) Equipment maintenance: At present, the basis for making equipment maintenance plans is the operation cycle of the equipment. Major repairs are needed; some equipment, even if they have not reached the specified age, have actually deteriorated and their efficiency has decreased. Although they can still operate, the operating costs are increasing day by day, and the efficiency is declining day by day. It has reached the point where repairs are necessary
