Optimised operation of a variable speed pump in a waste water pumping station

摘要

the invention concerns a method for operating a pumping station (1), in particular a abwasserpumpstation which pumpensumpf (3) with at least one support (4) and at least one end (5) and at least one in this pumpensumpf (3) arranged in the speed variable speed pump (2) includes.over a gradual period is on the rise (4) in the pumpensumpf (3) authority of water per unit time (qin (ti)) and zuflusswerte in a data storage unit (10) is saved.from the stored zuflusswerten values, the future optimierungszeitraum (topt) comprehensive reference curve (r) as a forecast for a forthcoming wassermengenzufluss (qin (ti), tiu2265t0) in the pumpensumpf (2) defined.using a numerical optimierungsverfahrens is then the optimierungszeitraum (topt) at least a first speed regulation (n (t0) of the pump (2),in the light of at least a certain optimierungsgru00f6u00dfe (egg) and at least one of optimierungsziel connected on the basis of the current level (p (t0)) in the pumpensumpf (3) and the predicted wassermengenzufluss (qin (ti)tiu2265t0) within the optimierungszeitraumes (topt) to achieve a zwischenpegelstandes (p (t0 + iu00b7u0394ti) or endpegelstands (p (t0 + topt) within or at the end of the optimierungszeitraumes (topt) is optimal. the pump (2) is then identified with the speed regulation (n (t0)) holdings.
