Abstract: A pump monitoring system associates a current operating state of a pump system including n≥1 pumps with one or more of k≥1 fault scenarios. The pump monitoring system includes an interface module for receiving at least one set of m≥2 operational values from the pump system. The m operational values define a current operational point in an m-dimensional operating space. A processing module processes operational values received by the interface module and consults given or determined model parameters describing a non-faulty model pump characteristic in the m-dimensional operating space and determines a k-dimensional decision vector with k decision vector components indicative of a deviation between an actual differential volume in the m-dimensional operating space based on distances between the m operational values and the non-faulty model pump characteristic, and a modeled differential volume in the m-dimensional operating space for the respective fault scenario.

Abstract: A pump system for a water supply mains has at least one pump device, a pressure detecting sensor at the pressure side of the pump device, a flow detecting sensor of the pump device, several pressure sensor units (D) remote arranged remotely from the pump device in different part regions of the mains, and a pump control device. The control device includes a model formation module designed in each case to produce a model (A) representing pressure loss from the pressure sensor to the position of the respective pressure sensor unit (D), based on several pressure measured values of at least two pressure sensor units (D) for the at least two associated part regions. The control device is designed for regulation of the pump device based on produced models (A), as well as to a corresponding method for regulation of a pump device in a water supply mains.

Abstract: A control system (15) controls a water supply from at least two separate input lines (3i-k) into a sector (1) of a water supply network. The control system (15) is configured to receive input flow information indicative of the water input flow (qi-k) through each of the input lines (3i-k). The control system (15) is configured to receive input pressure information indicative of the input pressure (pi) in at least one (3i) of the input lines (3i-k). The control system (15) is configured to receive pressure information indicative of at least one pressure value (pcri,m,n) determined by a pressure sensor (7m,n) within the sector (1). The control system (15) is configured to control the input pressure (pi) by controlling at least a pressure regulating system (13i) at an input line (3i) based on the input flow information from all input lines (3i-k) and based on the sector pressure information.

Abstract: A method of controlling a water reservoir supply pump arrangement determines a set value p, q, v, n of the pump arrangement based on an offset value pref, qref, nref, vref, G0 reduced by a component which is a function of a difference between an actual water level h and a predetermined water level href in a water reservoir. The difference is weighted by a proportional gain factor G. Further, a water reservoir supply pump arrangement is provided including at least one water pump and a control device for controlling the at least one pump.
