Abstract: A system and method for determining a reliability line rating for a transmission line is disclosed. In response to a line clearance measurement and a line temperature measurement received from a transmission line monitor coupled to a transmission line, the system generates a temperature-clearance model for the transmission line based on the received line clearance measurement and line temperature measurement. The system generates a plurality of past dynamic line ratings and determines a scaling factor based on the plurality of past dynamic line ratings. The system then generates a dynamic line rating for an interval of time in the future and scales the dynamic line rating in response to the scaling factor to obtain a reliability line rating for the interval.

Abstract: The present disclosure provides a methodology that incorporates real-time measurement of conductor temperatures and ground clearances using a transmission line monitor, coupled with information technology and data analytics, to allow utility operators to manage their transmission systems using a dynamic line rating process. Dynamic line ratings may incorporate real-time or near-real-time data of transmission line conditions in lieu of conservative assumptions, in order to more accurately assess actual transmission line performance such that more of the power conveying capacity of the existing transmission infrastructure can be accessed with continued compliance with safety requirements applicable to the transmission line system.
