Abstract
Systems and Methods are disclosed for providing measurement data redundancy to intelligent electronic devices (IEDs) in an electric power system, without additional redundant components. In various embodiments, a first measurement device obtains measurement data from a first portion of the electric power delivery system. A second measurement device obtains measurement data from a second portion of the electric power delivery system. A first IED monitors the first portion of the electric power delivery system based on measurement data associated with the first portion of the electric power delivery system, and a second IED monitors the second portion of the electric power delivery system based on measurement data associated with the second portion of the electric power delivery system. Assuming the first and second portions are coordinated, a communication system dynamically routes measurement data from the second measurement device to the first IED upon a failure of receiving digital measurements from the first measurement device.
