Ensuring safe power transmission

In order to ensure power transmission in 2024, especially in the dry season, Khanh Hoa Power Transmission (under Power Transmission Company 3) has proactively implemented specific solutions for each line and transformer station. 

Deploying many solutions

According to information from the National Center for Hydrometeorological Forecasting, the hot and dry situation in Khanh Hoa this year came earlier than in previous years. Therefore, the demand for electricity will tend to increase. This makes the work of operating the power transmission grid and ensuring electricity supply for the 2024 dry season very stressful.

Nguyen Nghia - Deputy Director of Khanh Hoa Power Transmission said that currently, the unit manages and operates 6 transmission lines with a total length of 721km; 1500kV transformer station and 3 220kV transformer stations with a total capacity of 3,153MVA ensure stable and continuous power supply for Khanh Hoa and neighboring provinces. From the beginning of 2024, the unit will receive an additional 500kV distribution yard from Van Phong 1 BOT Thermal Power Plant, energizing the double-circuit 220kV Nha Trang - Thap Cham line. It is expected that by the end of the year, the 220kV Van Ninh transformer station and the 220kV Nha Trang - Krong Buk circuit 2 line will be energized. Therefore, safe power transmission in the dry season plays a very important role for the socio-economic development.

In order to safely transmit electricity during the dry season, the unit has proactively developed specific plans and options in the management, operation, and overall inspection of lines and transformer stations to promptly detect and handle problems…

Applying technologies

Khanh Hoa Power Transmission undertakes the task of releasing and transmitting the entire capacity of power plants in the province to the national power system. A typical example is Van Phong 1 BOT Thermal Power Plant with a capacity of 1,320MVA (electricity output to the national grid in 2023 reached 2.1 billion kWh and is expected to exceed 7 billion kWh in 2024). In addition, the unit also transmits electricity from solar power plants such as KN Van Ninh, KN Cam Lam, Long Son, Trung Son, Ami... with a total capacity of more than 600MWp. In 2023, the unit transmitted nearly 63.8 billion kWh of electricity to the national grid; commercial electricity output reached nearly 6.9 billion kWh, 1.6 billion kWh of which was supplied to the load/more than 2.8 billion kWh in the whole province, equivalent to 66%.

To meet the task, in recent times, Khanh Hoa Power Transmission has increased the application of technology in managing and operating the transmission grid. The unit uses surveillance cameras on line poles to help check and control fire warnings; supervise construction and control motor vehicles to prevent violations of power grid safety corridors at intersections with Van Phong - Nha Trang expressway; using UAVs to help monitor and inspect equipment and route corridors conveniently and quickly. Periodic testing of equipment in 2024 at the 220kV and 500kV Van Phong transformer stations is also carried out according to plan, combined with maintenance and cleaning inspection of related equipment.

Nguyen Nghia said that in the coming time, especially in April, the unit will focus on completing the preparation of plans to ensure electricity supply for the dry season months in accordance with the direction of Electricity Transmission Company 3. In particular, the unit accelerates the work of clearing corridors to prevent fire; monitors the poles passing through the sugarcane growing area, coordinates with local authorities and sugar factories to speed up the progress of harvesting sugarcane in and near the line corridor; continues to strengthen propaganda in residential areas, schools, unions... to join hands with the electricity industry to protect the safety of high-voltage grid corridors…
