Central plant system with automated system curves calibration for pumps

A controller for central plant equipment comprising one or more processors and one or more non-transitory computer-readable media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:

• obtaining first values of flow rate of a fluid provided by one or more pumps to a building or campus and corresponding first values of a pressure differential across the building or campus during a first time period;
• generating a system curve for the building or campus that defines a relationship between the flow rate and the pressure differential using the first values of the flow rate and the pressure differential during the first time period;
• predicting a second value of the pressure differential across the building or campus during a second time period using the system curve and a second value of the flow rate during the second time period;
• and
• operating the one or more pumps to achieve the second value of the pressure differential across the building or campus during the second time period.
