Abstract:
A system for displaying dynamic on-line operating conditions of an interconnected power transmission network including means to monitor the interconnected power transmission network by measuring and correlating voltage magnitude and phase existing at a plurality of selected station busses of the interconnected power transmission network and to display isovoltage and isophase contour lines on a map representative of the interconnected power transmission network geographic area at a central location thereby showing existing operating conditions of the interconnected power transmission network wherein the location and nature of any disturbances occurring on the interconnected power transmission network is indicated on said map by a change in the positions of the isovoltage and isophase contour lines relative to the normal network operating isovoltage and isophase contour lines such that upon detection of an abnormal operating condition a system operator may initiate action within the interconnected power transmission network to correct for the specific system disturbance or abnormality.
