Problems solved by technology

[0004] The disadvantage of this known solution is that the pressure is always higher than it actually has to be, which leads to more water loss due to leaks and consumes more pumping energy than necessary

Embodiment Construction

[0054] figure 1 A sector 1 of a water supply system with three input lines 3i-k is shown. Sector 1 may be a concentration of consumers 5, eg, a town block. There are sector pressure sensors 7m,n located within sector 1 for providing sector pressure information. Sector pressure sensors 7m,n are located within sector 1 at critical points where local and / or global minimum pressures are expected. These critical points may be points with a high elevation or a large distance from the input pipeline 3i-k. The sector pressure sensors 7m,n may be called "critical pressure sensors" because they can indicate whether the pressure in sector 1 is too low. Anywhere else in sector 1, the pressure should be higher than the pressure at sector pressure sensor 7m,n.

[0055] At each of the three input lines 3i-k there is an input pressure sensor 9i-k and an input flow meter 11i-k arranged downstream of the pressure regulating system 13i-k. exist figure 1 Here, the pressure regulation system...

Abstract

The present disclosure relates to a control system (15) for controlling the supply of water from at least two separate input lines (3i-k) to a sector (1) of a water supply network, wherein the control system (15) is configured as continuous, periodic or Occasionally receive an indication of the water input flow (q i‑k ), wherein the control system (15) is configured to receive input pressure (p i ), wherein the control system (15) is configured to continuously, periodically or occasionally receive at least one pressure value (p cri,m,n ), wherein the control system (15) is configured to control at least a first pressure at a first input line (3i) by based on input flow information from all input lines (3i-k) and based on sector pressure information regulating system (13i) to control the input pressure (p i ).

Description

technical field [0001] The present disclosure relates to a control system and method for controlling the supply of water from at least two separate input lines into sectors of a water supply network, thereby controlling the water supply system. For example, a water supply network may be installed in a large building or agglomeration of buildings, such as a city, village, town, industrial area, neighborhood or quarter. A sector of a water network may be referred to as a District Metered Area (DMA) or a Pressure Management Area (PMA). Background technique [0002] Typically, water companies provide water to households and industries through water distribution networks distributed in DMAs or PMAs. Typically, each DMA or PMA is supplied with water by at least one water supply source (eg, a pumping station). However, in order to provide uninterrupted service from more than one water supply and / or redundancy of required water mixing, water is typically supplied to the DMA or PMA...
