Patent ID: 10801503

Abstract:
A multi-pump control system includes a processing module, a communication interface, a storage module and a control module configured to ramp up a speed of k pumps in addition to a subset j of i pumps of a system comprising N pumps running at a speed ωj providing a total head Δp, wherein N≥2, 1≤k<N and 1≤i<N, and to ramp down the i pumps of the subset j from the speed ωj to a lower speed ωm that is required for a subset m of i+k pumps to provide the total head Δp, and/or configured to ramp down the speed of k pumps of the subset j of i pumps and to ramp up the i-k pumps of a residual subset r from the speed ωj to a higher speed ωr that is required to provide the total head Δp.
