Development Directions of Box - Type Substations in the Artificial Intelligence Era
In the context of the global wave of digital transformation and the accelerated construction of smart grids, box - type substations, as the core power supply equipment for industrial parks, residential communities, and new energy power stations, are undergoing a profound technological revolution. The integration of artificial intelligence (AI) technology has completely changed the traditional operation and maintenance mode of box - type substations, which once relied on manual inspection and post - fault maintenance. Looking ahead, driven by continuous technological innovation, box - type substations will move towards multiple development directions such as refined intelligent monitoring, autonomous operation and control, integrated energy management, and intelligent lifecycle services in the AI era. These directions will not only enhance the stability and efficiency of power supply but also lay a solid foundation for the construction of a more reliable, efficient, and green modern power system.
Firstly, a comprehensive and refined intelligent monitoring and early warning system will become the basic configuration of box - type substations. Traditional box - type substations have long suffered from inadequate parameter monitoring and delayed fault early warning. For example, it was difficult to collect key data such as three - phase current and insulation resistance on the high - voltage side in real - time, and the oil temperature of transformers could only be read manually, which easily led to equipment failures due to untimely detection of hidden dangers. In the AI era, this situation will be completely reversed by the combination of multi - dimensional sensing equipment and advanced AI algorithms. Box - type substations will be equipped with a large number of high - precision sensors to comprehensively collect electrical parameters such as voltage, current, power factor, and harmonic waves in high - voltage, transformer, and low - voltage links, as well as environmental data including temperature, humidity, water immersion, and smoke inside the box.
Taking the intelligent solution of Li'an Technology as an example, by installing special detectors on different parts of the box - type substation, it can achieve high - precision real - time collection of core parameters. On this basis, AI algorithms will play a key role in data analysis. It is not only capable of identifying abnormal conditions such as overload, over - voltage, and temperature exceeding limits in real - time but also can predict potential faults by analyzing the changing trends of equipment load and operating temperature. For instance, when monitoring the transformer, the system can predict overheating faults according to the load change trend. When the temperature exceeds the limit, it will automatically start the fan for cooling, and even trigger tripping protection in extreme cases to avoid equipment damage from the source. Meanwhile, the AI system can accurately locate the fault point, cause, and alarm level once an abnormality is detected, and send alerts to relevant personnel through multiple channels such as mobile phone apps and short messages, realizing the transformation from passive maintenance to active prevention.
Secondly, autonomous operation and control and remote intelligent operation will significantly reduce the cost of on - site operations. The traditional operation mode of box - type substations requires a large number of on - site manual operations, such as manual recording of meter data and regular on - site inspections, which are not only inefficient but also have high safety risks. In the AI era, relying on the deep integration of AI technology and communication technology, box - type substations will gradually achieve autonomous operation and control capabilities. The AI system can automatically adjust the operating parameters of the substation according to real - time changes in grid load and environmental conditions. For example, it can automatically adjust the transformer tap and reactive power compensation device to optimize power distribution and improve the stability of the power grid. In terms of environmental management inside the box, the system can intelligently link with auxiliary equipment based on monitoring data. When the humidity exceeds the standard, it will automatically start the dehumidification device; when the temperature is too high, it will activate the heat dissipation device to ensure that the box - type substation is always in a stable operating environment.
In addition, remote intelligent operation and control will become a common function. With a double encryption review mechanism to ensure safety, operation and maintenance personnel can remotely complete operations such as switch opening and closing and capacitor compensation adjustment in the office. This subverts the traditional on - site operation mode. A practical case is that after an electric vehicle charging station adopted this remote control system, the monthly inspection frequency was reduced from 12 times to 2 times, and the operation and maintenance cost was reduced by 60%. It is estimated that such remote operation functions can reduce on - site operations by more than 90%, greatly improving the efficiency of operation and maintenance while reducing the safety risks caused by on - site operations.
Thirdly, the integration of energy storage and AI - driven collaborative management will become an important development direction to adapt to the access of distributed new energy. With the rapid development of new energy sources such as solar and wind power, the problem of unstable power output has become increasingly prominent, which puts higher requirements on the flexibility and adaptability of box - type substations. The emergence of energy storage - type box - type substations that integrate energy storage technology and traditional substation functions provides an effective solution to this problem. In the AI era, the combination of energy storage systems and AI technology will further tap the potential of energy utilization.
On one hand, AI will optimize the management of energy storage systems. The intelligent battery management system driven by AI can accurately monitor the state of each battery cell, including power, temperature, and cycle life, so as to balance the charging and discharging of the battery pack, extend the service life of the battery, and improve energy storage efficiency. On the other hand, AI can realize the collaborative scheduling between the box - type substation, the energy storage system, and the distributed new energy generation system. It can predict the power generation of new energy sources and the power demand of users based on big data analysis. By adjusting the charging and discharging strategies of the energy storage system, it can achieve peak shaving and valley filling of the power grid, absorb the unstable power output of new energy sources, and ensure the stability of the power supply. For example, during the peak period of new energy power generation, the excess power can be stored in the energy storage system; during the peak power consumption period or when the new energy power generation is insufficient, the stored energy can be released to meet the power demand, thus improving the effective utilization rate of electric energy.
Fourthly, the whole - lifecycle intelligent operation and maintenance and management system will be continuously improved to realize the refinement of operation and maintenance work. The traditional operation and maintenance of box - type substations are mostly based on fixed - cycle manual inspections, which are not only time - consuming and labor - intensive but also prone to omissions and failures in detecting hidden dangers in a timely manner. In the AI era, relying on technologies such as AI, big data, and cloud computing, box - type substations will build a whole - lifecycle intelligent operation and maintenance system to realize the transformation of operation and maintenance from "experience - driven" to "data - driven".
The AI system will automatically integrate inspection and maintenance data to generate standardized operation and maintenance reports, making the operation and maintenance work systematic and traceable. It can automatically formulate maintenance plans according to the whole lifecycle of equipment operation, record inspection tracks and maintenance content, and avoid manual omissions. At the same time, the system can generate weekly and monthly operation and maintenance analysis reports, summarizing key indicators such as alarm handling rate and defect elimination rate to quantify operation and maintenance efficiency and provide a basis for optimizing operation and maintenance processes. In addition, the cloud - based management model will make operation and maintenance more flexible. Operation and maintenance personnel can check the operating status of equipment anytime and anywhere through mobile phones, computers, and other terminals, conduct fault diagnosis and remote operation, which breaks the time and space limitations of traditional operation and maintenance and improves the response speed to faults. A residential community has proved that after the application of the intelligent box - type substation, the average response time to power failures has been shortened from 2 hours to 15 minutes.
Finally, the combination of digital visualization and AI security prevention and control will further enhance the safety of box - type substations. Safety issues such as unauthorized operation, circuit short circuits, and fires have always been the focus of attention in the operation of box - type substations. In the AI era, the combination of digital visualization technology and intelligent security equipment will build a multi - dimensional security protection network for box - type substations. The current, voltage, harmonic, and other parameters of the box - type substation, which were previously recorded manually, can now be collected in real - time through the intelligent system and displayed in 3D visualization, allowing operation and maintenance personnel to intuitively grasp the equipment operation status.
In terms of security prevention and control, the installation of door magnetic sensors and infrared intrusion detectors can immediately trigger dual alarms of pop - ups and short messages in case of abnormal opening of the box door, preventing safety risks caused by unauthorized operations. The smoke sensor and water immersion detector can detect potential safety hazards such as fires and water accumulation in a timely manner and link with the alarm system and even emergency shutdown devices to minimize losses. At the same time, AI algorithms can analyze the operating data of the equipment to identify abnormal electrical behaviors that are difficult to detect manually, such as hidden leakage currents and arc faults, and issue early warnings in advance to fundamentally eliminate safety hazards.
In conclusion, the AI era has opened a new chapter in the development of box - type substations. From comprehensive intelligent monitoring to autonomous operation and control, from the integration of energy storage collaboration to the whole - lifecycle intelligent operation and maintenance, every development direction is centered on improving the reliability, efficiency, and safety of power supply. With the continuous innovation and deep application of AI technology, box - type substations will no longer be just simple power transmission and distribution equipment. Instead, they will become an important part of the smart grid's "neural network", providing strong support for the high - quality development of the global energy industry and making positive contributions to the realization of the dual - carbon goal and the construction of a sustainable energy system.
