Pump stations and pumps control method in pipeline, involves total energy consumption of all pumps minimised at predetermined total flow and height

摘要

The method is for the control of pump stations and pumps in a pipeline and involves the total energy consumption of all pumps minimised at a predetermined total flow and height. The pipeline has a pump station PS1 with one pump (1), a pump station (PS2) with three pumps (2,3,4) and a pump stastion (PS3) with two pumps (5,6). - The first pump station is in flow direction connected via a pipeline segment (S12) with the second pump station, the second pump station is connected with the third pump station via a pipeline segment (S23) and the first pump station is connected via a pipeline segment (S1) with a first user (V1), which in turn is connected via a further pipeline segment (S2) with a further user (V2). The pump stations generally have several possible different pumps, producing via the users a regular and specific fluid quantity. Control is effected by the adjustment of the speed of the individual pumps and the pressure heights of the individual pump stations to be produced. - An INDEPENDENT CLAIM is also included for a computer program product.
