Electricity industry overcomes incidents caused by natural disasters

Muong Nhe Power workers fix problems caused by natural disasters.

In Muong Nhe district, due to the impact of prolonged rain and floods, the power grid system in the district was seriously affected. Some locations of power poles were affected, damaged, and had landslides in the pole foundations, which could cause power grid incidents; floodwaters eroded and caused power poles to fall, landslides in the pole foundations, and were at risk of falling poles (pole 347 of the 35kV line on Highway 371 E21.7; pole 12 of the 35kV line of Phu Ma NR; pole 2.2 of the 0.4kV line of Hui To 2 substation; pole 2.12 of the 0.4kV line of Pa My substation...). Muong Nhe Power Company has deployed and implemented the following plans: For locations with landslides in the pole foundations, the unit dug drainage ditches to prevent rainwater from flowing directly into the pole foundations, and continued to monitor and respond. As for the eroded areas, wait for the water to recede to make the water flow more evenly, not allowing the water to flow directly into the column foundation. Replace the collapsed column positions and assign people to regularly check and monitor when there is rain, wind, or storms.

Currently, Muong Nhe Power Company manages and operates 406.85km of 35kV lines, 192.34km of 0.4kV lines, 144 distribution transformer stations with a total capacity of 13,410kVA; manages 10,328 customers. Due to the large area, the unit's troubleshooting encounters many difficulties, especially at serious landslides and inter-commune and inter-village/hamlet roads that have not been invested in or concreted.

Mr. Pham Ba Dung, Director of Muong Nhe Power Company said: To promptly overcome the damage and impact caused by floods, the unit mobilized all its forces to work day and night. With the goal of ensuring safe and stable power supply for the people in the management area, the workers, especially the Medium and Low Voltage Grid Operation Management Team of the unit, always try to overcome difficulties and effectively implement the content of the plan that the unit has built. Thanks to that, the area under Muong Nhe Power Company's management has not been interrupted in terms of power supply; the power source is guaranteed to be maintained continuously and stably to serve the socio-economic activities and people's lives.

Not only in Muong Nhe district, prolonged heavy rain has caused landslides in the foundation of power lines, landslides above the power lines, dragging rocks, trees, causing power grid problems; flood water has eroded and fallen power lines in many other localities in the province. Many power projects have been damaged, such as: landslides in the foundation of power lines, with the risk of falling lines at the positions of column 39, 35kV Nam Ha road 371 E21.7 in Muong Toong commune (Muong Nhe district); column 45, 35kV Nam Ha road 375 E21.2 in Thanh Nua commune (Dien Bien district). Prolonged heavy rain has also affected many low-voltage poles: Na U, Phu Luong, He Muong, Nam He (Dien Bien district); Chung Chai, Nam Ke, Suoi Voi, Muong Toong, Quang Lam (Muong Nhe district); Ma Thi Ho, Si Pa Phin, Sa Long, Na Sang, Muong Muon (Muong Cha district); Cha Cang (Nam Po district)... these incidents have interrupted the power supply to loads with over 17 thousand customers. Prolonged heavy rain also caused landslides on the positive slope, causing the protective wall behind the Nam Pay Hydropower Plant's operating house to collapse. The landslides on the positive slope fell onto the road leading to the Nam Pay Hydropower Plant's valve house...

Proactively and promptly handling incidents caused by storms and rains, before this year's rainy season, Dien Bien Power Company has developed specific plans for natural disaster prevention, search and rescue suitable for each locality. At the same time, the Company and its affiliated Power Companies organized drills for natural disaster prevention and search and rescue to proactively handle and fix incidents in real conditions quickly and absolutely safely. With the spirit of determination to handle incidents in the shortest time according to the motto "4 on-site" and the principle "3 ready", the Power sector has ensured continuous power supply, preventing prolonged power outages in the province.
