Abstract
Systems and methods for dynamically updating flow bounds for one or more pumps are provided. An exemplary system includes one or more pumps, one or more processors, and one or more computer-readable media storing program instructions that, when executed by the one or more processors, cause the one or more processors to perform operations. The operations include updating bounds on flow provided by the one or more pumps based on one or more values of pump head, determining control decisions for the one or more pumps based on the bounds, and controlling the one or more pumps in accordance with the control decisions.
Claims18
A system comprising:
- one or more pumps;
- and
- one or more processors and one or more non-transitory computer-readable media storing program instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
- updating bounds on flow provided by the one or more pumps based on one or more functions of pump head, the functions connecting points on different pump speed curves for the one or more pumps, the points having flow values defined as percentages of flow values of most efficient points on the pump speed curves;
- determining control decisions for the one or more pumps based on the bounds;
- and
- controlling the one or more pumps in accordance with the control decisions.
A method of controlling equipment comprising:
- dynamically updating a constraint on a flow rate of a fluid created by operation of the equipment as a function of a pressure differential across the equipment, the function connecting points on different speed curves for the equipment, the points having flow rate values defined as percentages of flow rate values of most efficient points on the speed curves;
- determining control decisions for the equipment subject to the constraint;
- and
- operating the equipment in accordance with the control decisions.
One or more non-transitory computer-readable media storing program instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- dynamically updating a constraint on a flow rate of a fluid created by operation of the equipment as a function of a pressure differential across the equipment, the function connecting points on different speed curves for the equipment, the points having flow rate values defined as percentages of most efficient points on the speed curves;
- determining control decisions for the equipment subject to the constraint;
- and
- causing the equipment to operate in accordance with the control decisions.
