Centralized management and operation system for box transformer and distribution

background

With the development of the power grid, the demand for box type substations is also increasing. According to relevant data, the demand for box type substations in China reached 52500 units in 2021, and the market penetration rate has been increasing year by year. The difficulties related to the operation and maintenance of box type substations have also emerged. For example, cost increase and maintenance difficulty: traditional manual inspection methods are inefficient, data monitoring is insufficient, and there is a lack of effective remote monitoring systems, which makes it difficult to detect potential problems in a timely manner and increases fault response time. Incomplete data recording makes it difficult to conduct long-term trend analysis and preventive maintenance. Fault diagnosis is complex: When a box transformer malfunctions, it may be very difficult to determine the specific location and cause of the fault, especially for non professionals. The fault diagnosis process takes a long time, which affects the speed of restoring power supply.

system architecture

Centralized management and operation system for box transformer and distributionIt takes box type substations as the management object, installs box type substation gateways, and builds an integrated smart box type substation and operation and maintenance system based on the completion of intelligent transformation/new construction of box type substations, relying on Dianyi Cloud. We provide technical tools for intelligent operation and maintenance of transformer substations for property owners or maintenance providers. Through the web and APP, we can control the operation of transformer substations anytime and anywhere, complete intelligent inspections and dispatching of transformer substations online, truly achieve proactive prevention and maintenance of transformer substations, implement closed-loop defect management processes, timely eliminate hidden dangers, and ensure safe and reliable power supply. The specific system structure diagram is as follows

Advantages of Centralized Management and Operation System for Box Transformer and Distribution

1. Improve operational efficiency

• Real time monitoring: Through sensors and monitoring devices, the intelligent monitoring system can collect key parameters such as current, voltage, temperature, and humidity of the transformer in real time, and transmit the data to the monitoring center for analysis and processing, ensuring the normal operation of the transformer.

• Automated control: supports remote operation and control, and management personnel can monitor and control the operation status of the box anytime and anywhere through mobile phones or computers, improving work efficiency and convenience.

2. Enhance security

• Fault warning: Through the analysis of real-time monitoring data, the intelligent monitoring system can predict possible faults in the transformer and issue warning information in a timely manner to avoid the expansion of faults.

• Fault diagnosis: The system has fault diagnosis function, which can help management personnel quickly locate and handle faults, and reduce the impact of faults on the power system.

• Anti theft and anti pry: The integrated 360 degree panoramic video monitoring system can achieve all-weather monitoring, prevent human damage and theft, and improve the safety performance of the transformer.

3. Reduce operation and maintenance costs

• Reduce manual inspection: Intelligent monitoring systems can replace some manual inspection work, reduce on-site attendance, and lower operation and maintenance costs.

• Extend equipment lifespan: Through preventive maintenance, timely detection and handling of equipment abnormalities can extend the service life of equipment and reduce the frequency of equipment replacement.

4. Improve power supply reliability

• Quick response: The intelligent monitoring system can monitor the status of equipment in real time. Once any abnormalities are detected, immediate measures can be taken to reduce the duration and scope of power outages, and improve the reliability and stability of power supply.

• Data analysis: Through the analysis of historical data, the rules and trends of equipment operation can be discovered, providing a basis for optimizing operation and maintenance strategies and further improving power supply quality.

5. Implement unmanned operation

• Remote monitoring: The intelligent monitoring system can achieve remote control and unmanned operation, reducing the difficulty and cost of operation and maintenance, and improving the management level of the substation.

• Automated inspection: The system can automatically conduct regular inspections, generate inspection reports, and reduce manual intervention.

6. Strong environmental adaptability

• 24/7 monitoring: Whether it's sunny or rainy, the intelligent monitoring system can work normally and adapt to various harsh weather conditions.

• Multi scenario application: Not only can it be applied to traditional power systems, but it can also be widely used in renewable energy generation systems such as wind and solar energy, as well as new energy vehicle charging stations and other fields.

7. Improve user experience

• User friendly: Intelligent monitoring systems are typically equipped with user-friendly interfaces that allow managers to easily understand and operate them.

• Data visualization: Through charts, dashboards, and other forms, visually display the operating status and historical data of the transformer, making it easier for management personnel to make decisions.

8. In line with policy guidance

• Intelligent transformation: The intelligent monitoring system conforms to the policy orientation of national and local power departments to promote the digital transformation of the power system, and helps to enhance the modernization level of the power system.
