Abstract
A method of controlling a water reservoir supply pump arrangement determines a set value p, q, v, n of the pump arrangement based on an offset value p, q, n, v, Greduced by a component which is a function of a difference between an actual water level h and a predetermined water level hin a water reservoir. The difference is weighted by a proportional gain factor G. Further, a water reservoir supply pump arrangement is provided including at least one water pump and a control device for controlling the at least one pump.
