Power grid management in the 4.0 era: Using drones, artificial intelligence

Power grid management with surveillance cameras

Through more than 50 cameras installed in key locations, Power Transmission Company 2 (National Power Transmission Corporation) can easily monitor the situation of forest fires, storms, floods and many other factors that can affect the environment. may affect the transmission line, instead of having to go to the place like decades ago.

“There was 1 vehicle/fire detected at camera VT 47 DZ500kV Dong Hoi – Dong Ha M2 at 15:45:56 on May 18, 2022. Request the operator to check the camera and handle it”, was the message sent to the local transmission unit with an image of smoke rising near the 500kV Dong Hoi – Dong Ha transmission line.

“Thanks to the camera, incidents can be observed in time. The characteristics of the transmission lines managed by us are that the dry season affects forest fires and the rainy season landslides, so the installation of these cameras helps a lot in line management,” said the leader of the Power Transmission Company. 2 share.

From June 2021, PTC2 conducts research and application of artificial intelligence into the line surveillance camera system (mounted on the top of the pole). The goal is to combine the camera system to monitor the line being installed, the application of an artificial intelligence system to automatically identify motor vehicles that violate the safety corridor of the power grid, forest fires (including smoke columns, etc.). and fire) and automatically send warning messages to the manager.

According to the leader of this company, the application of CCTV in line operation management is a technological solution suitable to the current requirements of electricity grid operation. Support management units to operate the line to remotely observe the scene of the route under their management, thereby early detecting abnormal phenomena: fire near the corridor, landslide or construction Violating the route corridor has the risk of causing incidents….

This is also the basis for quickly assessing the situation of the power grid, helping to orientate the location and scope of the field, proactively arrange human resources, vehicles, tools, etc. to support quick access and handling. problems arise especially in times of natural disasters such as prolonged heavy rain, thunderstorms… thereby helping to optimize human resources, means, and improve production efficiency.

Unmanned aerial vehicle application

In addition, PTC2 also applies to test power transmission lines by drones automatically according to a predetermined schedule. Accordingly, continue to calibrate the automatic flight function by RTK signal for aircraft with RTK system to ensure the accuracy of the device during flight; deploying the flight to check the power grid by unmanned aerial vehicle (automatic or manual) through the assignment/receipt of tasks on the line management software system; building automatic flight routes for line segments (this work will be done regularly during operation at the units).

In addition, PTC2 also applies an artificial intelligence system to analyze and check image data.

In today’s life, activities such as flying kites, planting trees, agricultural technology… using light materials (such as nylon, fabric) are very popular. Therefore, the possibility of kite strings, plastic tarpaulins, and fabrics being swept up by the wind and flying into electric poles, conductors, and insulators for overhead power transmission line accessories is very high.

With the goal of quickly handling the situation that kites, cloths, tarpaulins, etc. flying entangled in power lines can cause power grid problems, reduce economic losses, and limit heavy and dangerous labor, PTC2 has researched , developed an unmanned aerial vehicle with a control system to spray fire to ignite objects entangled in a conductor structure without having to cut power to the line.

From 2020 up to now, PTC2 has used this flying device to handle dozens of cases of kites and tarps entangled in conductors and lightning protection lines of 500kV, 220kV lines without cutting power to the line, benefiting tens of billions of dong.

At the Central Power Corporation, EVNCPC has transferred 100% of 110kV substations operating unmanned, the connection rate of segmented equipment on the grid to the SCADA/DMS system is 93.4%. The digital transformation focus in this phase is on defining the digital transformation focus on smarter grid operation and management.

EVNCPC also deploys field inspection application for high, medium and low voltage power grids to improve the quality of field inspection work of workers, with the following 3 objectives: Eliminate paper and pens in the grid inspection stage. electricity, ensuring the inspection of workers is done quickly and conveniently on the mobile app; Building a device existence database as the basis for CBM/RCM implementation, ensuring that existing data is updated, stored and monitored on PMIS; Control and gradually improve the quality of workers’ inspection work (through tracking coordinates, assessing inspection frequency, frequency of detection of existence)…

The use of unmanned aerial vehicles, surveillance cameras, AI applications, etc. has contributed to the implementation of the policy of the Electricity of Vietnam on the application of science and technology 4.0, ensuring safe power transmission. continuously and stably for economic, political, social activities, national security and defense and Vietnam’s electricity market.
