摘要： The invention relates to a method for monitoring and controlling the operation of a pump station (1) comprising a tank (8) for storage of a liquid and at least one pump (2), the pump station (1) further comprises an outlet conduit (5) connected to the pump (2), the method comprising the steps of: determining the Geodetic head (Hgeo) of the pump station (1), determining the pumped Flow (Q) for a given pump operation duty point, determining the consumed Power (P) for the given pump operation duty point, and determining a Normalized Specific Energy (nSE) of the pump station (1) based on the determined values of Geodetic head (Hgeo), pumped Flow (Q) and consumed Power (P), by means of the formula (nSE) = (P/Q)/Hgeo .
