A control strategy for combined series-parallel pumps

Abstract

When a solution is adopted for a pumping irrigation system, to

variable or constant wealth, the engineer has to evaluate the

different alternatives to decide the most suitable system of

pumping. The majority of the companies of the sector, they

choose for systems of pump gradation in parallel at constant

speed, with what the variable that they control is the wealth. In

this paper there is proposed a system of pumping that connects

pumps in parallel and pumps in series, working at variable

speed, controlled by an algorithm that allows that every bomb

should work inside the area of maximum efficiency.
