"Digitizing" 110kV substations

- The application of "digital" solutions in the management and operation of 110kV substations has yielded positive results, helping Lang Son Power Company make significant strides in grid operation, thereby improving the reliability of electricity supply in the managed area.

Installation of additional T2 transformer equipment at Cao Loc 110kV Substation.

On May 15, 2026, Lang Son Power Company installed transformer T2 at Cao Loc 110kV Substation to supplement the remote data collection, monitoring, and control system, allowing connection to the regional remote control center and ensuring Cao Loc 110kV Substation operates in unmanned mode.

Mr. Vu Huu Tuong, Director of Lang Son High Voltage Grid Enterprise, Lang Son Power Company, said: When added, the T2 transformer will help the Cao Loc 110kV substation to connect and supply power back and forth with the Lang Son 110kV substation and the Loc Binh 110kV substation, thereby meeting the N-1 criterion (ensuring the power system remains stable and provides continuous power supply when a line or transformer fails or is disconnected for maintenance) in some areas, thereby improving the reliability of power supply.

Currently, Lang Son Power Company manages 9 110kV substations with a capacity of 475 MVA. Over the years, the company has proactively invested in, equipped, and implemented high-tech equipment and software such as: fully remote control and monitoring equipment via SCADA (Supervisory Control and Data Acquisition) system, smart electronic devices, remote-controlled cameras, sensors, operation monitoring equipment, fire alarm systems, and online battery monitoring... This has helped to fully "digitize" operations at the 110kV substations through automated processes, minimizing manual substation operation.

Mr. Nguyen Thanh Hai, Head of the Dispatching Department of Lang Son Power Company, shared: Currently, the collection of technical parameters and monitoring of operations at 110kV substations under the company's management is almost 100% automated. All switching and control operations of 110kV substation equipment are carried out directly at the remote control center through a modern system of equipment and high-tech application software. This allows on-duty staff to remotely check and analyze the operation of 110kV substations, while simultaneously overseeing the entire system from the 110kV substation to the power lines, including areas with difficult terrain or adverse weather conditions. As a result, potential risks of incidents on the power grid are detected early, assessed for risk levels, and addressed promptly; not only preventing incidents but also significantly reducing the pressure of on-site inspections and improving worker safety.

Beyond modernizing equipment and digitizing the management process of 110kV substations, Lang Son Power Company has completely replaced manual periodic maintenance methods with a data-driven approach using sensors to monitor temperature, humidity, and oil levels of equipment within the 110kV substations, thereby creating appropriate maintenance schedules. Thanks to these sensors and early warning systems, abnormal signs in the substations are detected promptly, allowing dispatchers to take quick corrective measures. This optimizes substation operational efficiency and minimizes the risk of serious incidents.

Mr. Pham Minh Tuan, Deputy Director of Lang Son Power Company, said: The "digitization" of 110kV substations is the optimal solution for the current power grid system, optimizing investment costs for cables and intermediate equipment, thereby meeting the needs of power transmission and ensuring stable power supply to serve the socio -economic development of the province.

Following the directives of Vietnam Electricity Group and the Northern Power Corporation, one of the key directions for Lang Son Power Company in the coming period is to continue investing in, developing, and applying high-tech software, artificial intelligence (AI), and the Internet of Things (IoT) in monitoring and controlling 110kV substations; gradually aiming towards the goal of implementing smart grid management and operation in the province by 2030.
