Under the current backdrop of dual carbon emission targets and energy consumption control, industrial parks, as major energy consumers, face immense pressure to conserve energy, reduce emissions, and control costs. Traditional single-circuit, extensive energy metering is no longer sufficient to meet the demands of modern intelligent management.
Through the deep integration of multi-circuit energy meters (hardware) and energy management systems (system platforms), a comprehensive energy management solution can be built for industrial parks, encompassing “high-density front-end data collection” and “digital back-end analysis,” enabling visible, controllable, and optimizable energy consumption.
Four Major Pain Points in Industrial Park Energy Management
Numerous Distribution Nodes and Limited Space: Numerous enterprises and densely packed outgoing circuits within the park necessitate the installation of traditional single-circuit meters in each distribution box, resulting in insufficient space, high overall costs, and significant construction difficulties.
Disjointed Energy Consumption Data: The lack of real-time, refined data makes it impossible to accurately grasp the actual electricity consumption patterns of each workshop, piece of equipment, or tenant, leading to unclear internal electricity cost allocation and difficulties in cost accounting.
Disconnected Energy Consumption Data: Low maintenance efficiency and numerous hidden dangers: Reliance on manual meter reading and inspection leads to delayed fault detection and makes it difficult to prevent potential electrical fires caused by overloads and leakage.
Uncontrollable power quality: Frequent start-ups and shutdowns of high-power industrial equipment can generate harmonics and voltage fluctuations, affecting the safe operation of precision instruments in the park.
Hardware and Software Collaborative Solution Architecture
This solution adopts a typical “end-pipe-cloud” IoT architecture, with its core being the high-density data acquisition from multi-circuit energy meters at the front end and the intelligent analysis from the back-end Energy Management System (EMS).
1. Front-end Data Acquisition (Multi-circuit Energy Meters)
Multi-circuit energy meters are deployed in various distribution boxes within the park (such as main distribution cabinets, floor distribution boxes, and workshop power cabinets).
Highly integrated metering: A single meter can simultaneously measure 12 single-phase circuits (or the corresponding number of three-phase circuits), perfectly solving the space constraint problem.
Power outage-free construction: With open-type current transformers (CTs), enterprises in the park do not need to stop production or lose power during the upgrade process.
Comprehensive Power Monitoring: Accurately collects comprehensive electrical parameters including voltage, current, power, energy, and 2nd-31st harmonics.
2. Transmission Network (Smart Gateway/Communication Layer)
Multi-circuit energy meters in the field are connected to the communication gateway via an RS485(Modbus-RTU protocol).
The gateway uploads the high-frequency collected power data to the energy management system platform in real time and securely via Ethernet, 4G, WiFi, or LoRa.
3. Application Core (Energy Management System – EMS)
As the “brain” of the entire solution, the energy management system centrally stores, deeply analyzes, and visualizes the data uploaded by the front-end multi-circuit energy meters, providing a wealth of business application modules.
Core Functions and Application Scenarios
Core Advantages of the Solution
High Cost-Effectiveness (Hardware Savings): Replacing dozens of traditional meters with a single multi-circuit energy meter saves 30%-50% on hardware costs, wiring time, and DIN rail space.
Lightweight Deployment (Fast Construction): Modular design and non-intrusive (no wiring required) installation minimize disruption to normal production in the industrial park.
On-Demand Expansion (High Flexibility): As the park expands or new businesses are introduced, the energy management system can be seamlessly upgraded simply by adding multi-circuit energy meter modules at the front end, without requiring system reconstruction.
Data-Driven Decision-Making (Precise Management): Say goodbye to unclear accounting. The system transforms underlying meter data into decision-making data for managers, helping the park implement KPI energy consumption assessments.
Expected Benefits
Directly Reduced Electricity Costs: By identifying waste such as “lights left on unnecessarily” and “idle equipment,” the system optimizes electricity usage periods (off-peak production), potentially reducing overall electricity costs for the park by 8%-15%.
Improved Operation and Maintenance Efficiency: Changing the traditional manual meter reading method, the system automatically collects data and issues alarms, reducing power distribution maintenance labor costs by over 50%.
Meeting Policy Compliance Requirements: The system can automatically generate dual-control reports on carbon emissions and energy consumption that comply with government regulatory requirements, helping industrial parks apply for green park and zero-carbon park status and enhance their brand competitiveness.
Conclusion
Multi-circuit energy meters act as the “nerve tentacles” reaching deep into the end of the park’s power distribution network, while the energy management system serves as the “digital brain” coordinating the overall system. The powerful combination of multi-circuit energy meters and the energy management system, with extremely low deployment costs and high integration, bridges the last mile of energy digitalization in industrial parks, making it an ideal choice for parks to achieve green and low-carbon transformation and refined operation.
