Abstract:In this paper it is presented how an active power filter can generate energy savings in a water pumping station.It is very well known that it was made a very important modernizations in terms of energy savings by using variable speed. The pumps are controlled by power converters which become a nonlinear load for the grid. In those conditions the problems of power factor cannot be managed with simple capacitor banks.An evaluation of the solutions, which seems to be the active power filter, is made in this paper… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
