ENSURE SAFE AND SMOOTH POWER TRANSMISSION IN THE SOUTH CENTRAL REGION, CENTRAL HIGHLANDS DURING THE HOT SEASON

n the face of the forecast that the demand for power transmission will increase in this year’s hot season, is the unit that manages and operates the transmission grid in the South Central region and the Central Highlands – which is considered the “burden” of the transmission system. North – South electricity, Power Transmission Company 3 (PTC 3) has made a thorough preparation.

Clearing millions of square meters of  corridors

This area in the dry season often has the potential for forest fires outside the corridor, which is likely to cause electrical problems. Right from the end of 2021, Power Transmission Company 3 has implemented corridor treatment, corona discharge test and insulation cleaning plan for contaminated areas, to ensure power supply in the dry season of the year. 2022.

According to Mr. Nguyen Manh Tuong – Head of Safety Department of PTC 3, up to now, the company has cleared, cleared and created a safe fire-proof corridor for the transmission line with a volume of over 3.7 million m2 , reaching 98.93% of the plan, expected to be completed by mid-May. For the sugarcane cultivation area, the regional power transmissions continue to monitor and actively work with the owners of the households, sugar mills, the People’s Committees of communes, wards and townships to have a plan to harvest sugarcane early.

The regional power transmissions are regularly patrolled until the risk of fire causing a breakdown is completely eliminated. Some locations and key columns have been installed with surveillance cameras. The company has installed propaganda signs, road crossing warning signs at poles with phase height – low ground, dangerous sea, boundary sign of transmission line corridor.

PTC 3 has worked with local authorities, the Steering Committee for Safety and Protection of the High Voltage Power Grid, and the Economic Security Division (PA04) – police of the provinces where the line passes, on ensuring safe operation, stabilize the transmission grid; signed a commitment to ensure the safety of the electricity grid corridor with agricultural, forestry, protection forest management boards, People’s Committees of communes, wards, towns and households living along the line, households with land, fields, and fields. sugarcane fields under the lines.

Increased frequency of testing

Due to the very fast development of solar and wind power sources in the past short time, some lines operated by PTC 3 are always in a state of full load, sometimes overloaded. Along with the economy recovering from the COVID-19 epidemic, industrial and consumer loads have increased compared to before, so the company closely monitors lines and transformers that are likely to be overloaded, to coordinate with dispatching levels to make timely adjustments to avoid incidents affecting the operation of the power system. The company increased the frequency of testing, measuring joint temperature, checking weak pulse columns, etc.

However, in order to ensure the safe operation of the transmission grid, Mr. Nguyen Manh Tuong – Head of Safety Department of PTC 3 suggested local departments and people to coordinate, support and well implement regulations on ensuring safety for electricity generation. maintaining high-voltage grid safety corridor, especially swidden burning in and near the corridor; status of kite flying near the corridor,…

PTC 3 also recommends that agricultural, forestry, rubber companies, and protection forest management boards where the transmission line passes through coordinate and create conditions for the unit to cut tall trees outside the corridor to be able to fall into the corridor, to eliminate the risk of violating the safety distance.
