Management and operation of power transmission lines is always an important task, requiring continuous and close supervision. However, according to statistics, violations of power grid corridors still occur with high frequency and are difficult to control if only relying on manual patrols.
Notably, the phenomenon of kite dropping near the line still occurs frequently, kite ropes entangled in the power lines can easily cause power release, safety jumps, and disruption of power supply.
In addition, at civil construction sites and transport infrastructure, construction vehicles such as cranes, cranes, excavators move close to the power grid corridor. If there is no supervision, it is easy to violate safety distances, posing a potential risk of touching power lines.
Currently, EVNHANOI is managing 66 110/220kV transformer stations with a total capacity of 9,503 MVA (including 152 110kV, 9,003 MVA transformers; and 2 220kV, 500 MVA transformers).
The Corporation also operates 122 sections of the 1,125.47 km 110kV line, including 995.28 km of overhead lines and 170.19 km of underground cables; along with 2 sections of the 220kV line, 8.84 km long (including 8.34 km of overhead lines and 0.5 km of underground cables).
The large infrastructure block, spread over a large area, creates significant pressure on management and operation tasks, requiring modern, proactive and highly automated monitoring solutions.
Therefore, to enhance capacity in operational management (QLVH), EVNHANOI has researched an AI Camera system applying artificial intelligence technology combined with light distance measurement technology (Lidar) to monitor the high-voltage power grid safety corridor.
AI cameras are capable of automatically detecting and warning of unsafe risks such as construction vehicles (cranes, cranes, excavators, etc.) moving near the route corridor, kitchens, fish fishing, and growing trees violating safety distance or generating smoke and fire near the line.
All images from the AI Camera system will be continuously analyzed at the Monitoring Center, helping operators quickly grasp and handle potential risks.
In particular, the cameras also integrate a loudspeaker system, automatically issuing propaganda bulletins, raising public awareness in protecting the power grid corridor - Mr. Hoang Quang Tho - Head of Technical and Operation Department (Hanoi High Voltage Grid Company) - shared.
In fact, in the past, hundreds of corridor violations such as kitchens release, garbage burning, and construction vehicles violating safe distances have been detected promptly thanks to the AI monitoring system in the electricity industry.
Notably, this device is designed with active source using solar panels and storage devices, meeting the installation at all pole locations on the line without dependence on residential power sources.
According to industry experts, the application of AI Camera not only helps reduce the workload of patrol workers, but also contributes to the comprehensive modernization of environmental protection work. This solution aims to operate the power grid safely, reliably, and proactively prevent incidents.
In the face of strong digitalization, the electricity industry expects that corridor monitoring solutions using AI cameras will continue to be replicated on a large scale. In the future, the system will be supplemented with multi-layered data analysis features, automatic navigation, and synchronization with modern control systems such as SCADA/PMIS.
These steps not only optimize the efficiency of the national grid but also contribute to realizing the goal of developing a smart, sustainable power grid in Vietnam.
EVNHANOI's application of Cameras in operations monitoring is a clear demonstration that digital transformation is bringing breakthrough solutions and practical value in the electricity industry.
