Swapping mobile power transformers for repairs without causing power outages in the mountainous area of ​​A Luoi

When demand is high

Experience from recent years shows that in the dry season in Hue City, the heat is often prolonged and severe. Not only agencies, factories, and enterprises but also households consume a high amount of electricity, an increase of 20-30%.

This year, the weather forecast is extreme, with the possibility of severe heat lasting longer in the dry season than in previous years. Based on that reality, PC Hue predicts that the maximum capacity during the dry season this year in Hue City will reach 400MW. This is also the basis for PC Hue to forecast the actual source and load situation of the distribution grid under its management, and at the same time, develop an operation plan to ensure dry season power supply of the distribution system in 2025.

Currently, units under PC Hue are strengthening the inspection of the load network of transformers, power lines, forecasting the load network situation and developing operating methods in situations when power grid incidents occur. In addition, the units are also stepping up the inspection of power sources and grids; urgently completing the repair and maintenance of the grid in the first quarter of 2025...

A regulation of PC Hue currently applied when construction units repair, maintain, or build new power grids will thoroughly apply solutions that do not cause power outages for customers, such as using generators for important loads, mobile transformers, hot repair of power grids, cleaning insulation with high pressure water. Units also strengthen technical management, have solutions to increase capacity, and timely load sharing of distribution transformer stations at risk of being overloaded during the dry season.

PC Hue also promotes the exploitation and effective operation of the Remote Control Center in monitoring and operating the power grid, focusing on exploiting data from remote metering systems from 220/110kV transformer stations and 22kV distribution stations to detect early abnormalities; ensuring the quantity of spare equipment and materials to be ready to mobilize to handle incidents in order to restore power to customers as quickly as possible.

To achieve the goal of ensuring safe and continuous power supply, PC Hue complies with the operational direction of the Central Power System Control Center, closely coordinates with Power Transmission Company 2, PC Quang Tri and Da Nang Power Company Limited in operating the 110kV inter-provincial and city power grid, ensuring maximum support for power supply to loads in Hue City.

Save electricity to reduce power shortage pressure

To operate the power grid safely, provide continuous power and practice energy saving (E&S), PC Hue has requested units to deploy the work of ensuring the power grid corridor and promoting safe electricity use for people. Specifically, strengthening inspection work to protect the safety of operation and safe power supply for high-voltage power grids. Accordingly, PC Hue coordinates with localities to promote the propaganda of protecting the power grid corridor; at the same time, handling organizations and individuals violating the safety of operating high-voltage power grids.

PC Hue also proactively works with large electricity consumers in the area. Thereby, sharing information, solutions, and plans of the electricity industry in ensuring safe and stable electricity supply for local loads.

According to Mr. Nguyen Dai Phuc, Director of PC Hue, in addition to the above technical solutions, to maintain a stable and continuous power source during the dry season, customers need to use electricity efficiently and economically. Therefore, PC Hue continues to promote the habit of saving electricity for customers, such as: turning off lights, fans, air conditioners... in the house when not in use; using air conditioners to cool at moderate temperatures, from 26 degrees Celsius or higher with fans; taking advantage of natural light and energy sources instead of conventional electrical equipment. Companies, factories, and enterprises should balance their production schedules in the direction of reducing electricity use during peak hours.

PC Hue will regularly organize consulting programs for customers to invest in energy-saving and high-performance production equipment. At the same time, coordinate to monitor and control the quality of electricity in localities, units, and production facilities with large electricity consumption...

Reality has proven that renewable energy is the most effective and feasible solution to limit the power shortage in the dry season. At this time, the power supply situation is still guaranteed for customers to use electricity according to their needs, and there has not been a shortage. However, in the upcoming hot summer months, customers' demand for electricity will increase. To limit the power shortage along with the power supply solutions of the electricity industry, it is necessary to have the cooperation and cooperation of each person in using electricity more economically and reasonably...
