Abstract: Methods and systems for secured control of circuit breakers in an electric power substation against undesired direct operation. Consequences of a malicious action are prevented or mitigated using a validation approach that either blocks the command or ensures a negligible effect on system operation. An example method, suitable for implementation in a monitoring device in an electric power substation, includes receiving a command to open or close a circuit breaker. In response, one or more state parameters for the electric power network that comprises the substation are then predicted, the predicted state parameters reflecting an operating state for the network under the assumption that the received command is executed. The method further comprises comparing the predicted one or more state parameters to corresponding operational limits. Execution of the command is then blocked, in response to determining that one or more of the predicted state parameters violate the corresponding operational limits.

Abstract: Detection of cyber-attacks on sampled values in a substation environment is based on the correlations and/or the Mahalanobis distances between the sampled values for two monitored points in the substation. An example method includes the collecting of a first series of sampled current and/or voltage data for a first monitored point. The method further includes receiving, from a second monitoring device in the power system, a second series of sampled current and/or voltage data for a second monitored point. This second series of sampled current and/or voltage data corresponds in time to the first series. Dissimilarity metrics are calculated for the first and second series, where the dissimilarity metrics are based on the covariances of the first and second series. The dissimilarity metrics are compared to a first threshold value, and an alarm is triggered in response to determining that said comparing indicates a dissimilarity that exceeds a target dissimilarity.

Abstract: Systems and methods for fault detection and protection in electric power systems that evaluates electromagnetic transients caused by faults. A fault can be detected using sampled data from a first monitored point in the power system. Detection of fault transients and associated characteristics, including transient direction, can also be extracted through evaluation of sample data from other monitored points in the power system. A monitoring device can evaluate whether to trip a switching device in response to the detection of the fault and based on confirmation of an indication of detection of fault transients at the other monitored points of the power system. The determination of whether to trip or activate the switching device can also be based on other factors, including the timing of receipt of an indication of the detection of the fault transients and/or an evaluation of the characteristics of the detected transients.
