Quality of service terrain map for power utlilities

摘要

A method of providing a graphic display of an electrical distribution network to provide network personnel insight into network operations comprises: monitoring a section of the distribution network including a plurality of interconnected line segments within the section so to obtain information about a predetermined performance characteristic of the section over the line segments; processing the information to ascertain relative performance characteristic values within different portions of the section and displaying the results of the processing in a graphic format which allows an observer to readily ascertain what is occurring at respective line segments and determine whether operations within the network section are acceptable, and if not, where a problem is occurring, and the magnitude of the problem; displaying the information including a three-dimensional display in which one axis represents line segments within the network section, a second axis a representative value of the performance characteristic, and the third axis periods of time. The display provides a quality of service map for the network section.
