Low-energy intelligent information management system

Building/enterprise energy management systems are designed to enhance existing energy management levels, implement effective management of daily operations, maintenance, and user energy consumption behavior patterns in buildings/enterprises, and achieve energy savings through scientifically feasible energy efficiency improvement strategies. Based on real-time monitoring of energy supply and transmission systems, the system collects, analyzes, and processes energy consumption data, environmental information, equipment status, and operational data to derive decision-making insights related to energy consumption and energy efficiency, helping management personnel understand historical and current energy usage conditions.

Significance of constructing energy consumption management systems for industrial enterprises, buildings, hospitals, schools, and other sectors:

1) Informatization and visualization of energy consumption processes

Currently, most domestic enterprises rely on manual periodic meter reading to collect data on electricity and energy consumption. This method suffers from issues such as data lag, poor timeliness, and limited data scope, making it difficult to obtain real-time energy consumption data for various production processes and key energy-consuming equipment. The enterprise energy efficiency management information system enables online monitoring of dynamic production energy consumption information across the entire enterprise (or group), integrating this data with corresponding equipment, workshops, and team production metrics. On-site operational personnel can access real-time energy consumption status, unit energy consumption data, energy consumption trends, and real-time operational parameters for production processes and critical equipment.

2) Energy consumption/efficiency information statistics and management

The enterprise energy efficiency management system automatically generates various energy consumption information statistical graphs, curves, and reports, such as daily, weekly, monthly, and annual energy consumption reports for electricity, water, gas, coal, etc. These reports are categorized at three levels: entire facility, workshop, and key energy-consuming equipment, providing users with insights into energy consumption structures and cost analysis, and evaluating the effectiveness and associated impacts of energy-saving measures.

The system offers comprehensive energy consumption/efficiency statistical reports through menu-driven or direct button-guided interface modes. The graphical interface includes macro-level enterprise energy consumption data and related information, quickly and intuitively reflecting real-time and historical energy consumption/efficiency information for the enterprise, production workshops, teams, and key production processes.

3) Historical energy consumption data comparison and analysis

The enterprise energy efficiency management system features robust historical energy consumption data tracing and analysis capabilities. Energy efficiency management and production process analysts can flexibly set operational parameters as needed, generating various energy consumption data reports and curves for different time periods, such as equipment-specific consumption, production line and team-specific consumption. It allows querying and tracing energy consumption data for key energy-consuming equipment and production lines using multiple methods, and comparing and analyzing trends of various parameters to identify underlying issues in energy consumption structures and processes. This enables proposing solutions and recommendations for improving and optimizing enterprise energy consumption structures and methods.

Through dynamic unit production energy consumption curves and data, enterprises can visually compare their production energy consumption against international and domestic standards, guiding and adjusting production, management, and processes to maintain scientific and reasonable levels of unit energy consumption and energy efficiency.

4) Power quality and harmonic monitoring and analysis

The widespread application of power electronics technology in areas such as electrified railways, electrolysis plants, arc furnace smelting, and motor variable frequency speed control has improved production efficiency but also generated significant harmonic pollution in power grids, leading to harmonic and power quality issues. The electricity and energy efficiency management information system monitors power quality and harmonic components online. Through harmonic component diagrams and trend charts, users can promptly understand the actual electricity usage environment, avoid harmonic hazards and power quality problems, and reduce harmonic and reactive power losses in the power supply system. Typically, purchasing harmonic monitoring equipment requires substantial investment, but this system simultaneously achieves dual functions of monitoring and analyzing both energy consumption status and harmonics.

After the building/enterprise energy management system is established, it achieves the following objectives:

(1) Real-time monitoring, fault alerts, and automated management of medium and low voltage power distribution systems;

(2) Online monitoring, automatic collection, and storage of various energy consumption data and energy efficiency indicators, with flexible and diverse query methods. Energy consumption types include: electricity, water, cooling/heating;

(3) Establishment of a management system for statistical analysis and internal accounting of energy consumption based on dimensions such as physical space, key equipment, categorized items, and tenants;

(4) Independent energy consumption accounting for various public areas, enabling energy cost allocation, implementing energy consumption quota standards, standardizing energy usage methods, and controlling energy expenditures;

(5) Scientific calculation and real-time monitoring of building energy consumption indicators through manual entry of operational data, and evaluation of current energy consumption levels across different areas;

(6) Provision of multiple energy efficiency analysis tools to help management personnel identify unreasonable energy usage phenomena;

(7) Providing data support for energy-saving technological transformations and verifying the effectiveness of energy-saving renovations;
