Disclosed herein is an approach that uses a motor protection system (205, 210) to protect a process operation (100). In one aspect, a motor protection system (205, 210) in conjunction with a controller (220) monitor the performance of redundant motor-driven prime movers (105, 110) having a lead motor-driven prime mover (105) and a lag motor-driven prime mover (110). In one embodiment, the controller (220) controls operation of the redundant motor-driven prime movers (105, 110) as a function of motor protection measurements generated from the motor protection system (205, 210). In particular, the controller (220) uses the motor protection measurements to determine if the lead motor-driven prime mover (105) is in distress. The controller (220) activates operation of the lag motor-driven prime mover (110) in response to determining that the lead motor-driven prime mover (105) is in distress. In one embodiment, the controller (220) activates operation of the lag motor-driven prime mover (110) prior to tripping the distressed lead motor-driven prime mover (105). |
