Abstract: An electrical generator and method for operating the same are provided. Accordingly, the generator includes a non-rotatable component supporting a field winding assembly and a rotatable component oriented to rotate relative thereto. The generator also includes an armature winding assembly fixedly coupled to the rotatable component so as to rotate therewith during operation of the generator. The generator also includes a resistive assembly fixedly coupled to the rotatable component so as to rotate therewith during the operation of the generator. The resistive assembly electrically couples at least two separate phase windings of the armature winding assembly. The resistive assembly is also configured to introduce a resistance into the armature winding assembly in response to an electrical fault.

Abstract: A method of controlling an electric motor assembly includes detecting a backspin event of an electric motor, and managing a response to the detected backspin event of the electric motor. The backspin event of the electric motor is detected based at least in part on feedback from a sensor configured to measure a current or a voltage on a cable coupled to the electric motor. The response includes communicating an alert to personnel, controlling the voltage on the cable to be less than a voltage threshold, or any combination thereof.

Abstract: A method includes controlling a first power output to an electric machine during a transient event. Controlling the first power output includes measuring values of the first power output provided to the electric machine during the transient event, receiving an estimated speed input of the electric machine, determining adjustment commands to compensate the first power output for the transient event of the electric machine, generating switch commands for gate drives of a variable frequency drive (VFD) based at least in part on the adjustment commands, and modifying the first power output during the transient event based on the switch commands.

Abstract: Power delivery systems and methods described herein conductively couple several input lines with a cable that conducts a multi-phase electric current. The input lines separately conduct different phases of the electric current. Output lines are conductively coupled with plural machines, and separately conduct the different phases of the electric current. Plural switching devices are conductively coupled with the input lines and with the output lines, and are used to control the switching devices in order to conduct the different phases of the electric current to the machines. A first set of the switching devices is closed to separately conduct the different phases of the electric current to a first machine of the machines. A different, second set of the switching devices is separately closed to separately conduct the different phases of the electric current to a different, second machine of the machines.
