    Abstract: A hybrid power plant including a plurality of power sources and controllers, a hybrid plant controller, and a computing system. The controllers operate the power sources according to operating set points. The hybrid plant controller transmits the operating set points to the controllers. The computing system is coupled to the hybrid plant controller and receives a first set of input parameters from a first subscriber, and carries out a first level of services to which the first subscriber subscribes to determine operating parameters for the first subscriber. The computing system receives a second set of input parameters from a second subscriber and carries out a second level of services to which the second subscriber subscribes to determine operating parameters for the second subscriber. The computing system then computes the operating set points based on aggregate operating parameters for the first and second subscribers.

    Abstract: A system and method for identifying turn faults in a stator of a motor are provided. The method includes determining a normalized cross-coupled impedance from the symmetrical components of measured voltages and currents of the motor. Additionally, the normalized cross-coupled impedance may be normalized to a negative sequence impedance. The negative sequence impedance may be determined through a regression analysis using parameters of the motor, such as line-to-line voltage, horsepower, and number of poles. A system is provided that includes a device having a memory and processor configured to determine a normalized cross- coupled impedance, compare the normalized cross-coupled impedance to one or more thresholds, and trigger and alarm and/or trip the motor
