Abstract

See full text

A method is provided for operating a wastewater pumping station of a wastewater pumping network. The pumping station includes a pump, that starts pumping if a level of a wastewater in a tank exceeds a first wastewater level, and the pump stops pumping if the level of the wastewater in the tank drops below a second level. The method includes determining a magnitude of a parameter (Psys, Q, n, ΔP, Pelectrical, cos φ, I) expressing the load of the wastewater pumping network. If it is determined that the magnitude of the parameter has passed a specified threshold, the pump is activated to start pumping in an energy optimization mode. A control unit is also provided for the wastewater pumping station of the wastewater pumping network, and a system is provided for centrally controlling a plurality of pumps of wastewater pumping stations in a wastewater pumping network.
