Standard frequency converters (FCs) are evaluated in this work as
a universal solution for photovoltaic (PV) water pumping systems.
FCs can be connected directly to a PV generator to power centrifugal
submersible pumps driven by three-phase asynchronous induction motors.
In comparison with dedicated products, the use of standard FCs and
centrifugal motopumps encompasses several advantages: power range,
broad range of products and technological independence. This paper
describes the main rules to implement standard FCs in PV pumping
systems, and presents a model to estimate its performance from standard
pumps manufacturers? data. The experimental validation of the model
is also presented. Copyright © 2003 John Wiley & Sons, Ltd.
