Abstract: A method for aggregating anomalous values is provided. The method comprises obtaining operational data from at least one machine and calculating at least one exceptional anomaly score from the operational data. The exceptional anomaly scores can then be aggregated to identify acute or chronic anomalous values.

Abstract: A method for determining whether an operational metric representing the performance of a target machine has an anomalous value is provided. The method includes collecting operational data from at least one machine, and calculating at least one exceptional anomaly score from the obtained operational data.

Abstract: A system and method for establishing communications in a power plant comprises a power generation system having an interface for establishing wireless communication, at least one power plant auxiliary system having an interface for enabling wireless communication, and a wireless communications link, having at least two redundant wireless communications channels, established between the power generation system and the power plant auxiliary system. The two redundant wireless communications channels may be two redundant wireless radio frequency channels. The communications link may be established utilizing a network communications controller which wirelessly communicates with the power generation system and the power plant auxiliary system. One or more of the power plant auxiliary systems may communicate with the network communications controller through a repeater.

Abstract: The method includes repairing the stator bar end fittings used for the electrical and hydraulic connections at the stator bar ends of a generator with suitable integrity to be as good as new or better than an in-kind replacement with new components for the stator bar. The method addresses the need to repair leaks in liquid cooled generator end windings and the respective end fittings. In particular, the method repairs leaks that develop between the joints of interior adjacent strands and between the outermost strands and the end fitting. The method employs the replacement of the original end fitting with another end fitting similar in geometry. A majority of the original end fitting along with the original window (if any) is preserved and utilized as a ring to surround and compress the strand bundle, with the original braze intact, thus preserving the original geometry of the strand bundle.
