Shulou(Shulou.com)06/02 Report--

Industrial enterprises account for the largest proportion of energy consumption, which is also an important part of enterprise costs, accounting for more than 70% of total energy consumption. This result not only hinders the sustainable development of China's economy, energy conservation and emission reduction, but also affects the market competitiveness of enterprises. Therefore, reducing energy consumption is an effective way for enterprises to reduce costs.

Energy consumption on-line monitoring system is a set of energy on-line monitoring and analysis management system with the core purpose of saving energy and reducing consumption. It is mainly through the comprehensive monitoring, diagnosis and analysis of the energy consumption and working conditions of the energy-saving equipment, the main process equipment and the main energy-consuming equipment of the key energy-using units. then it adopts the combination of equipment energy saving, process optimization energy saving, management strategy optimization energy saving and so on. To provide key energy users with system energy-saving products, energy-saving strategies, energy-saving management and service platforms adapted to the differential characteristics of process conditions of user production lines, and energy consumption online monitoring system plus ruiecjo micro-understanding. And then construct the "enterprise (group) energy management and control center" to provide products, technology, strategies, methods and information support for the economic and rational use of energy, so that the entire production line of key energy users can save 5% and 30% of energy.

Key energy consumption unit energy consumption on-line monitoring system:

1. Scope of application

This specification is used to guide the energy classification data collection of the key energy consumption unit energy consumption on-line monitoring system 138.2311.8291, and the data collection of each energy use unit is carried out in accordance with the energy collection mode stipulated in this specification.

3. Terminology

3.1 Metering equipment

It refers to all kinds of measuring instruments such as liquid flow meter, gas flow meter, watt-hour meter, automobile scale, track scale, belt scale and so on.

3.2 production process control system

It refers to the automatic control system based on microprocessor, which detects, records, adjusts, controls and displays the parameters of the production process. Such as distributed control system (DCS system), programmable logic controller (PLC) and so on.

3.3 production Monitoring and Management system

It refers to the data bridge between various production process control systems and enterprise management application systems, which provides multi-level real-time data support for management. Such as SIS, MES and so on.

3.4 Management Information system

It refers to a kind of software that can reflect most of the functions of enterprise management (including decision-making, planning, organization, leadership, monitoring, analysis, etc.), can provide real-time, relevant, accurate and complete data, and provide decision-making basis for managers.

3.5 Energy consumption monitoring terminal equipment

It refers to the integrated server placed in the computer room of key energy-consuming units, which has the functions of online collection, collection, verification, storage, upload and remote upgrade of energy-related data.

4 Energy data

4.1 Energy classification

According to the energy form and measurement mode, the energy collected by the energy consumption on-line monitoring system is divided into five categories, namely, electric power, heat, solid energy, gaseous energy and liquid energy. In addition to electricity as a single source of energy, the other four energy sources also contain a variety of specific types of energy.

4.2 Energy collection items

In order to obtain the data of all kinds of energy consumption or output and external supply of key energy users, all kinds of energy data of key energy users should be collected.

For all kinds of steam, the energy consumption monitoring equipment should be uniformly converted, summarized into thermal power (GJ) and uploaded.

For all kinds of energy data, it is appropriate to upload energy conversion standard coal coefficient.

5. Collection mode of energy consumption

5.1 Classification of collection methods for energy consumption

The relevant data of each type of energy purchase, consumption, output and other related data in the key energy consumption unit energy consumption online monitoring system are mainly obtained through four kinds of on-line collection methods. they are on-site measurement instruments, production process control system, production monitoring management system, management information system.
