Abstract
A system for detecting and locating a disturbance event within a power grid includes a series of frequency disturbance recorders (FDRs) taking measurements in the power grid at dispersed points of the power grid, an information management system, configured to receive data from the series of FDRs and analyze the received data and a communications network interconnecting the series of FDRs and the information management system. The information management system is configured to examine orders and patterns of receipt of frequency changes at the FDRs in the data caused by the disturbance event and to triangulate a location of the disturbance event based on the orders and patterns of receipt of the frequency changes. Example methods of detection and location of disturbance events are also described.
