Abstract
The disclosure provides a controller and server combination, which implements a set of software programs to control a booster pump system. In a preferred embodiment, the software derives quadratic models for the pump performance curves, and the system curve. The system monitors the flow rate of the system, the pump performance curve model and the system curve model to adjust the drive frequency and the number of active pumps to meet flow rate demand efficiency.

A controller for operating a pump system for a hydraulic system comprising:
- a processor, including a memory;
- a signal generator, operatively connected to the processor;
- a set of pumps, operatively connected to the signal generator and supplying water to the hydraulic system;
- a suction pressure sensor, operatively connected to the hydraulic system and the processor, generating a first pressure signal;
- a discharge pressure sensor, operatively connected to the hydraulic system and the processor, generating a second pressure signal;
- a set of instructions, stored in the memory, which when executed cause the pump system to implement the steps of:
- deriving a quadratic system curve model;
- reading the first pressure signal;
- deriving a quadratic pump performance curve model;
- reading the second pressure signal;
- and
- initiating the quadratic system curve model and the quadratic pump performance curve model, using the first pressure signal and the second pressure signal, to alternatively activate and deactivate a pump, of the set of pumps, to supply the hydraulic system.
