Western Power Transmission 1 enhances transmission loss reduction

Reducing power loss on the grid system is included in the competition criteria, contributing to increasing production and business efficiency, saving costs, and at the same time creating reliability of the power system.

Western Power Transmission 1 is assigned to manage and operate the 220 kV and 500 kV power transmission grid in the Mekong Delta region passing through Can Tho City, Hau Giang Province, Soc Trang Province and Bac Lieu Province, including 10 transformer stations, including 02 500 kV stations with a total capacity of 2,400 MVA, 08 220 kV transformer stations with a total capacity of 2,250 MVA, 06 500 kV lines with a total length of 180.94 km, 30 220 kV lines with a total length of 885.96 km.

With the development of the transmission grid, the transmission output on the 220 kV grid in the first 7 months of 2024 reached 6.436 billion kWh, an increase of 849 million kWh - equivalent to 15.2% over the same period (5.587 billion kWh). The power loss on the 220 kV grid reached 0.925%, equivalent to the same period (0.921%).

Workers of Bac Lieu Power Transmission Team use UAV to inspect power lines.

Transmission output on the 500 kV grid in the first 7 months of 2024 reached 4.378 billion kWh, equivalent to the same period (4.391 billion kWh), 500 kV grid loss reached 0.16%, down 0.03% over the same period (0.19%).

To achieve this result, since the beginning of 2024, Western Power Transmission 1 has organized the dissemination of 2024 economic and technical indicators to all employees at the unit, focusing on solutions to ensure the completion of the target of reducing electricity loss.

From the assigned technical and economic indicators, the unit has assigned power loss indicators to teams and stations; established a volume of solutions to prevent and reduce incidents and power loss and proposed solutions to prevent incidents caused by animals at transformer stations for the most effective implementation.

To effectively manage power loss, over the years, Western Power Transmission 1 has implemented many solutions in operation management such as coordinating with construction units to optimize power outage time, prioritizing construction solutions that do not require power outages, minimizing work power outage time; combining line repair work and periodic testing of station equipment.

In addition, information collection and forecasting of electricity transmission output and monthly electricity loss are linked to planned construction power outages, power source modes, loads, etc.

Regularly monitor the equipment operation at transformer stations to avoid overloading and overloading. Regularly check the transformer cooling system, electrical resistance, and equipment heaters to ensure they work in accordance with the ambient temperature.

Detect and promptly handle equipment abnormalities, terminal contacts with high temperature increase, limit grid losses; limit multiple power outages, large-scale power outages. Conduct periodic equipment inspections according to regulations.

In 2024, periodic inspections were carried out on 25 boundary meters, 32 internal meters; 06 boundary TUs and TIs.

Check and clear fireproof corridors.

Organize inspection and maintenance of road crossing signs, river crossing signs, overhead power warning signs, propaganda panels, etc. Regularly organize measurement and inspection of insulating chain halos, check corridor illumination, ensure clear lines and safe operation.

The inspection of contact surface cleaning, tightening of lightning arrester bolts at the top of the pole, inspection of grounding contact surface cleaning at the base of the pole, and cleaning of power line porcelain reached 34.5% compared to the 2024 plan,...

In addition, Western Power Transmission 1 has also directed departments, teams, and stations to save electricity, raise awareness of all staff in using energy economically and efficiently; encourage the replacement of outdated, low-efficiency electrical equipment with new, high-efficiency technologies, to improve electricity efficiency...

In the last months of 2024, Western Power Transmission 1 will continue to implement effective solutions and apply new solutions that bring practical results to contribute to reducing power loss across the entire power grid system managed by the Unit.
