Acrel Substation Operation and Maintenance Cloud Platform: Intelligent Management and Control Across All Scenarios, Building a Zero-Fault Power Operation and Maintenance System

I. Introduction: The Dilemma of Traditional Operation and Maintenance and the Inevitable Choice of Digital Transformation

In an industrial park, a cable overheating and fire caused by a missed manual inspection resulted in a single incident loss exceeding 2 million yuan; in a commercial complex, scattered and difficult-to-trace data led to an inflated annual electricity bill of 300,000 yuan. These kinds of efficiency and economic losses caused by inefficient operation and maintenance management result in hidden costs exceeding 500 billion yuan annually for Chinese enterprises. Traditional manual inspection and discrete system management models are no longer able to cope with the multiple challenges of the explosive growth of distributed energy, the high sensitivity of equipment, and increasingly stringent carbon emission regulations.

Acrel's substation operation and maintenance cloud platform, with "data-driven and intelligent prediction" as its core concept, achieves a revolutionary leap from "passive repair" to "proactive defense" through a "cloud-edge-device" collaborative architecture and AI-driven deep optimization algorithms. Whether it's an industrial park, a commercial complex, a hospital, or a data center, the system can complete a panoramic analysis of the power system within 10 seconds. Through technologies such as intelligent early warning, remote control, and energy efficiency optimization, it can improve overall operation and maintenance efficiency by 40%-70%, helping enterprises build a new smart power ecosystem that is "highly reliable, low-risk, and free of hidden dangers."

II. Core Technologies: An Intelligent Closed Loop from Hazard Identification to Precise Management

The Acrel Substation Operation and Maintenance Cloud Platform is not simply an aggregation of traditional systems, but a power hub integrating IoT, edge computing, and AI technologies.

1. Comprehensive Perception: The "Digital Nerve" of the Power Network

Multi-Dimensional Data Acquisition:

High-Precision Monitoring: The ADW300-4G IoT meter monitors over 30 parameters in real time, including voltage, current, and power, with an accuracy of 0.5 level. In a real-world test in an industrial park in Wuxi, it successfully captured a minute current fluctuation of 0.1A, avoiding inflated costs caused by metering errors.

Full-Scene Coverage: Integrates environmental sensors such as temperature and humidity, smoke, water immersion, and access control, linked with video surveillance to construct a 3D power topology map, providing second-level early warning for abnormal conditions.

Anti-Interference Communication Network:

Utilizing a 5G+LoRa hybrid network, it supports breakpoint resumption and AES-256 encryption, maintaining 99.9% data transmission reliability even in complex industrial environments, ensuring zero-delay command execution. 2. Intelligent Control: The "Super Brain" of the Power System

Dynamic Load Control:

Combining real-time electricity prices and grid load forecasts, the system automatically adjusts transformer loads, reducing demand-based electricity costs. After implementation, a steel company saved 21% on basic electricity costs annually, resulting in cost savings of 2 million yuan.

Precise Fault Location:

Supporting over 800 alarm types (such as overvoltage, leakage, and equipment offline), the system quickly locates fault points using AI algorithms, reducing fault response time to 30 minutes. After deployment at a supercomputing center, annual downtime incidents decreased to zero, and overall energy efficiency improved by 12%.

3. AI Prediction and Autonomous Learning:

Equipment Health Management:

Based on sensor data such as vibration and temperature, an equipment health model is established, providing early warnings of potential faults up to 72 hours in advance. A chemical industrial park used this function to reduce unplanned downtime by 60% and lower annual maintenance costs by 1.5 million yuan.

Energy Efficiency Optimization Strategies:

Dynamically generate energy consumption reports, identify high-energy-consuming processes, and propose energy-saving suggestions. A commercial complex, through energy efficiency analysis, reduced its average monthly electricity consumption by 15% and received bonus points for LEED green building certification.

4. Policy Compliance Support:

Automatically generate power quality reports and carbon footprint data to help companies obtain ISO50001 certification, national green data center qualifications, and improve their ESG rating.

III. Full-Scenario Empowerment: From Chip Manufacturing to Data Centers – “Power Guardians”

Acrel Substation Operation and Maintenance Cloud Platform provides customized solutions for different scenario needs:

1. Industrial Parks: Solving Pain Points in High-Energy-Consuming Scenarios

Integrated Source-Grid-Load-Storage:

Real-time monitoring of production equipment energy consumption, optimizing operating parameters of equipment such as air compressors and refrigeration units through AI algorithms. After application, an electronics factory saw an 18% improvement in overall energy efficiency, saving 2 million yuan in electricity costs annually.

Dynamic Reactive Power Compensation:

ANSVC intelligent reactive power compensation devices track nonlinear loads such as electric arc furnaces and frequency converters in real time, raising the power factor to above 0.98. A chemical plant saved 1.2 million yuan in electricity costs annually.

2. Commercial Complexes: Reshaping the Value of Energy Services

Energy Consumption Behavior Guidance:

Real-time generation of merchant energy consumption rankings, conducting “Energy Saving Pioneer” selection activities. After a pilot program at a shopping mall, the percentage of merchants proactively turning off non-essential electrical appliances increased from 35% to 78%, resulting in a 22% decrease in average monthly electricity consumption.

Integrated Parking and Charging:

The system seamlessly integrates with the parking management system. Users can automatically start charging via license plate recognition, and parking and charging fees are combined upon departure. After implementation at the Shanghai Sunshine Riverside Center, charging users' dwell time increased by 30%, boosting mall sales by 15%.

3. Healthcare and Education: Ensuring the Operation of Sensitive Equipment

Voltage Sag Protection:

At a top-tier hospital, DVR devices ensure the normal operation of precision equipment such as CT and MRI machines during voltage sags, preventing over 3 million yuan in misdiagnosis losses annually.

Intelligent Inspection Management:

After Wuhan Children's Hospital integrated the platform, the number of on-duty staff was reduced from 12 to 3. Energy efficiency analysis helped save approximately 15% on electricity costs, and digitized equipment records improved management efficiency.

4. Data Center: Building a Zero-Interference Power Supply Environment

Multi-level Power Protection:

Configuring Dynamic Voltage Restorer (DVR), high-capacity UPS, and Automatic Transfer Switch (ATS) for backup power, achieving millisecond-level fault switching. After implementation in a financial data center, the average annual power outage time decreased from 45 minutes to 0 seconds, and maintenance costs decreased by 30%.

Harmonic and Reactive Power Coordination:

Centralized compensation + dynamic follow-up compensation strategy ensures harmonic distortion rate <3%, power factor > 0.99, and annual electricity cost savings exceeding 5 million yuan.
