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 Pn and Δ{tilde over (p)}n, wherein each of the approximated pump characteristics Pn and Δ{tilde over (p)}n is unambiguously defined by a pair of parameters (θ1, θ2; θ3, θ4). The system is configured to store the pair of parameters (θ1, θ2; θ3, θ4) for each of the determined approximated pump characteristics Pn and Δ{tilde over (p)}n.

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.

The alarm management module (13) is configured to process at least one level variable (h) indicative of a filling level of the wastewater pit (1) and at least one capacity variable (p %, P %, C %) indicative of a pumping capacity of the wastewater pumping station. The alarm management module (13) is configured to trigger an intervention alarm only if all of the following conditions are met: a) the at least one level variable (h) is at or above a predetermined alarm level threshold (hm), b) the at least one level variable (h) is increasing, and c) the at least one capacity variable (p %, P %, C %) is below a capacity threshold.

Abstract: A control system controls a fluid distribution system that includes consumer branches arranged in parallel. Each consumer branch includes a consumer element (31) consuming fluid and/or thermal energy, a regulating device (9) receiving a control value regulating a flow of fluid and/or thermal energy through the consumer branch, and a sensor (11) providing a measured value of the consumer branch. The control system includes a saturation calculation module (21) providing a saturation value, for each operational consumer branch, indicative of the saturation degree of the associated consumer branch, and a saturation compensation module (23) receiving the saturation values and altering a reference value. The altered reference value is based on an initial reference value and the saturation values from all consumer branches. The consumer branch regulating device, of each operational consumer branch, is controllable based on the altered reference value and the measured value of the associated consumer branch.

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 control method for a pump assembly (10, 12) in a pneumatic or hydraulic system controls a speed (n) of the pump assembly (10, 12) in dependence on at least one variable (Dp, p, T, xp) which is detected in the system. An error signal (e) is produced from the detected variable (Dp, p, T, xp) on the basis of a sectionwise monotonic function. On the basis of the error signal, the speed (n) of the pump assembly (10, 12) is controlled.

Abstract: The method serves for operating at least one pump assembly (1, 1a, 5) of a multitude of pump assemblies (1, 1a, 5) which each comprise a programmable electronic motor (4, 4a, 6) control for individual pumps or groups or pumps, and which are at least temporarily data-connected to a server (8) via a network, with which data, in particular parameters and/or operating data of the multitude of pump assemblies (1, 1a, 5) is transferred via the network to a server (8) and is stored there in a data base. The stored data is processed according to defined typically statistical computation rules, whereupon the at least one pump assembly is then adapted in its programming via the network, on the basis of the processed data.
