Operational Analysis of Dynamic Line Ratings

Overhead line is an important asset for power industries. Rising demand in electricity, environmental concerns and cheaper electricity prices are some important factors behind operating the lines at their maximum potential. Replacing overhead lines and/or constructing new lines are not only expensive but also at the same time raise environmental concerns. However, rating overhead lines based on their natural capacity besides being cost effective is a technically feasible solution. In this project, the operational analysis of dynamic line ratings (DLR) is conducted to analyze potential of DLR when practically implemented across overhead line in a sub transmission network. It further guides system operators in fully utilizing the line capacity to its maximum potential. The project also investigates the impact of Flexible AC Transmission System (FACTS) device in the presence of DLR technique to control power flow from wind generators for stabilized and controlled transfer of electricity.
