Possibilities For Increasing The Transmission Capacity Of Overhead Lines In Real Meteorological Conditions

This paper analyzes the influence of relevant meteorological parameters on the current load of overhead power lines, based on the corresponding mathematical model for calculation of the permitted current load. It points the importance of monitoring of meteorological parameters and the temperature of conductors in real time, along the route of the line, for the purpose of accurate dynamic calculations and forecasts of permitted current load. This facilitates the selection of relevant management actions to ensure safe and economical operation of the power system. Also, congestion in transmission lines is avoided and placement of energy from intermittent renewable energy sources in certain regions is enabled, according to the requirements of the electricity market.
