Zusammenfassung: | A system includes a dynamic compressor and a controller. The dynamic compressor includes a motor having a driveshaft rotatably supported within the dynamic compressor and a compression mechanism connected to the driveshaft and operable to compress a working fluid upon rotation of the driveshaft. The controller is connected to the motor and includes a processor and a memory. The memory stores instructions that program the processor to operate the motor to compress the working fluid at a motor speed greater than a predicted minimum surge speed plus a control margin, determine when surge events have occurred, store, in the memory, an indication of each surge event that the processor determined to have occurred, and determine whether or not to take a protective action when the processor determines that a surge event has occurred. |
