Abstract: A computer-implemented method of detecting events in downhole drilling data. The method includes training, by a computer, a machine learning model based on historical MWD data received from one or more MWD tools to generate a trained machine learning model. The method includes monitoring, by the computer, a stream of substantially real-time MWD data from the one or more MWD tools. The method includes detecting, by the computer, one or more events in the stream of substantially real-time MWD data using the trained machine learning model. The method includes determining, by the computer, that the detected one or more events are associated with one or more MWD data types. The method includes generating, by the computer, a notification that the one or more events have been detected.

Abstract: An apparatus and method compensate for the sensitivity of at least one line current differential element of a first current differential relay providing differential protection for a transmission line of a power system during a single-phase pole-open condition. The apparatus includes a first delta filter configured to remove a first pre-fault current from a first fault current of the transmission line to derive a compensated first current phasor. The apparatus also includes a second delta filter configured to remove a second pre-fault current from a second fault current of the transmission line to derive a compensated second current phasor. The compensated first and second current phasors are provided to the at least one line current differential element to compensate the sensitivity of the at least one line current differential element.
