SUAI has developed a system for modeling heat losses in overhead power transmission lines that takes into account specific meteorological conditions.
The development allows for a more accurate assessment of how weather factors affect the operation of power grids, and helps to increase their reliability and energy efficiency.
Overhead power lines are exposed to the environment on a daily basis: air temperature, wind, solar radiation, humidity, and icing. All these factors directly affect the heating of the wires, the change in their electrical resistance and, as a result, the loss of electricity. In real conditions, these parameters are constantly changing, but in practice they are often taken into account only approximately.
— The computer program developed at SUAI allows you to simulate thermal processes in power transmission lines in dynamics, taking into account real weather conditions and load current. The system is based on a mathematical model of the thermal balance of the wire, including Joule heating, convective and radiative heat exchange, the influence of solar radiation and the presence of ice. As a result, it is possible to predict the temperature of the wire, thermal power losses and changes in electrical resistance under various weather scenarios,» comments Maya Sergeantova, PhD, Associate Professor of the Department of Electromechanics and Robotics at SUAI.
The practical value of the development lies in the fact that it can be used in the planning and operation of power grids. A more accurate prediction of the operating modes of power lines makes it possible to optimize their capacity, reduce power losses and reduce the risk of accidents related to overheating of wires or icing.
