Abstract:
1. A system for generating dynamic line ratings comprising: a module for receiving physical data concerning a power line, said data having: location data including geographic locations of the path of said power line; at least one physical measurement concerning a physical condition of said power line; and at least one physical fact concerning said power line; a module for storing said data concerning said power line; a module for receiving periodically updated weather prediction information associated with a select set of said geographic locations of the path of said power line; and a processor, said processor configured to receive input on a load passing through said power line and to determine if said load is above or below a predetermined load threshold, wherein if said power line has a load exceeding said threshold, said processor calculates a line rating based on said at least one physical measurements data concerning said power line, and wherein if said power line has a load below said threshold, said processor calculates a line rating based on said weather prediction information associated with each of said geographic locations of the path of said power line, wherein said processor periodically receives updated input on said load passing through said power line and, if said load has changed from its previously detected level to a new level that switches from one side of said threshold to another side of said threshold, said processor dynamically switches said line rating to a rating based on said physical measurements data if previously based on said weather prediction information or switches said line rating to a rating based on said weather prediction information if previously based on said physical measurements data.
