Abstract
A multi-pump control system with a control module, a processing module, communication interface, and a storage module. The system is configured to change a number n of running pumps, and receive a signal indicative of a power consumption P and information about a speed ω of one of the n running pumps before and after two different changes of the number n of running pumps. The system is configured to determine, before and after at least two different changes of the number n of running pumps, without a measurement of a differential pressure Δp and of a flow Q, two approximated pump characteristics Pand Δ{tilde over (p)}, wherein each of the approximated pump characteristics Pand Δ{tilde over (p)}is unambiguously defined by a pair of parameters (θ, θ; θ, θ). The system is configured to store the pair of parameters (θ, θ; θ, θ) for each of the determined approximated pump characteristics Pand Δ{tilde over (p)}.
