Matlab Software to Determine the Saving in Parallel Pumps Optimal Operation Systems, by Using Variable Speed

In this paper a software is described, which was made with the purpose to determines the systems behaviour in which many centrifugal pumps are involved operating in parallel. The software permits to determinate the flux distribution to give for each pump, for a total flow to supply, in order to obtain a minimum of total losses. For this purpose it is taken in consideration that each pump is driven for an induction motor, fed for a variable frequency voltage driver.
