Abstract

See full text

A dynamic line rating determination apparatus configured to control the current applied to a power line conductor by determining a dynamic maximum current rating for said power line conductor, based on measured voltage and current phase vectors taken at two temporally spaced sample times, the phase vectors including a voltage and current phase vector for each phase of electrical power carried by the power line conductor at a first and second end of the power line conductor; and determining the dynamic maximum current rating by; applying the phase vectors to a power line model to estimate the conductor temperature, applying the estimate to a thermal model to predict a steady state temperature that the power line conductor will reach, and calculate the dynamic maximum current rating based on the prediction of the steady state temperature, a power line conductor current, and a maximum temperature limitation value.
