Abstract: A sub-sea power transmission/distribution network includes a plurality of standard proven power converter building blocks on each of the power source side and the sub-sea load side. The power source side converters and the sub-sea load side converters are each configured to provide a modular stacked dc (MSDC) converter architecture. The power source side converters are further configured to share the load equally or in proportion to their individual power ratings. The configurations are based on corresponding droop curves representative of MSDC link current magnitude data and average output voltage data of the power source side converters.

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.
