Systems and methods for performing a redundancy check using intelligent electronic devices in an electric power system

Abstract

Provided is an intelligent electronic device-to-intelligent electronic device direct communication system in a power system, for performing a power system data redundancy check therebetween. The communication includes a first intelligent electronic device adapted for deriving power system data from a selected portion of the power system. The first intelligent electronic device is associated with a first transmit module for transmitting the derived power system data. A second intelligent electronic device is further provided and adapted for deriving power system data from the selected portion of the power system, wherein the second intelligent electronic device is associated with a first receive module. The first receive module of the second intelligent electronic device is coupled to the first transmit module of the first intelligent electronic device via a communication link, such that the first receive module is adapted to receive the derived power system data transmitted by the first intelligent electronic device. The second intelligent electronic device is further adapted to provide a redundancy check between the first and second intelligent electronic devices by comparing the power system data derived by the second intelligent electronic device with the power system data transmitted thereto from the first intelligent electronic device. In other embodiments, the power system data transmission can be bidirectional and redundancy check can be performed in both intelligent electronic devices.
