Abstract:
A pump control system includes a plurality of different variable speed pumps. Each of the pumps can be operated at a different speed to equalize pump loads. A system wide proportional integral differential control loop increases and decreases the speed of all pump motors to maintain a desired system output pressure. A second proportional integral differential control loop associated with each pump adjusts pump speed to equalize a load profile for each respective pump.
