US Patent 9519014 Systems and methods for calculating power transmission line capacity

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.
