Abstract
A system and a method for controlling the pressure of a fluid in a distribution network. The network includes at least one pump station having a number of pumps that are configured to pressurize the fluid from a supply line; means for determining at least one flow value (Q) of at least a part of the distribution network and a control unit for controlling the activity and/or speed of the pump(s) of the pump station according to a predefined pump curve defining the relationship between the pressure and the flow of the fluid pressurized by the pump station. The control unit is configured to change the pump curve automatically according to at least one determined flow value (Q).
