Abstract:
1. A system, comprising: at least two redundant motor-driven prime movers, wherein one of the at least two redundant motor-driven prime movers comprises a lead motor-driven prime mover and a second of the at least two redundant motor-driven prime movers comprises a lag motor-driven prime mover that operates in response to the lead motor-driven prime mover being in distress; a plurality of sensors, coupled to the at least two redundant motor-driven prime movers, that measure operational data associated with the at least two redundant motor-driven prime movers; a motor protection system, coupled to the plurality of sensors, that generates a plurality of motor protection measurements from the operational data measured by the plurality of sensors; and a controller, coupled to the at least two redundant motor-driven prime movers and the motor protection system, that controls operation of the at least two redundant motor-driven prime movers as a function of the plurality of motor protection measurements, wherein the controller uses the plurality of motor protection measurements to determine if the lead motor-driven prime mover is in distress, the controller activating operation of the lag motor-driven prime mover in response to determining that the lead motor-driven prime mover is in distress, wherein the controller activates operation of the lag motor-driven prime mover prior to tripping the distressed lead motor-driven prime mover.
