Subotica: Impact of Wind on Transmission Line Stability

The northern Bačka region, and specifically the area around Subotica, is known for its open plains where winds can reach gale force. For the electrical power system, these winds represent one of the most significant natural challenges. While the grid is designed to withstand heavy stress, the specific meteorological conditions in this part of Vojvodina require constant monitoring and specialized engineering measures.

The Phenomenon of Conductor 'Galloping'

When strong winds combine with freezing rain or wet snow, an asymmetrical ice coating forms on transmission line conductors. Wind blowing across such conductors causes them to oscillate violently, a phenomenon known as 'galloping.' These amplitudes can be large enough to cause conductors to touch, resulting in short circuits and automatic system shut-offs to protect the equipment.

Maintaining Protective Corridors

In the Subotica area, great emphasis is placed on maintaining transmission line corridors. Wind can often blow branches or entire trees onto the grid if vegetation is not regularly cleared. The planned works you see on our portal often include 'vegetation management' within the protective zone, which is a crucial preventive measure for stability during the windy autumn and winter months.

Investing in Stability

Modernizing the grid in the north involves installing vibration dampers and reinforcing support towers. Additionally, wherever economically feasible, low-voltage networks are being replaced with underground cables, which are entirely immune to wind gusts. These projects significantly reduce unplanned outages and ensure a more stable supply for households and businesses in Subotica.
