Centrifugal Motor-Pump System Model intended for the Photovoltaic Pumping applications

Yaichi M., Fellah M.-K.

Przegląd Elektrotechniczny

2013

R. 89, nr 8

111--115

The Saharan medium by its arid nature and the availability of solar immense can return the application of the water pumping via photovoltaic pumping. To improve their performances for such type of systems, a theoretical study based on experimental tests is necessary. In this paper, the system to be modelled consists of an asynchronous motor coupled to a centrifugal pump immersed of type SPA in order to obtain a pumped flow and efficiency in function of the frequency of the stator voltage for pumping head given. The result has been very satisfactory.

W artykule opisano możliwość nawadniania obszarów Sahary za pośrednictwem pomp zaislanych fotowoltaicznie. Zamodelowano system składający się z silnika asynchronicznego połączonego z pompą.

Study of Single Sensor Based Maximum Power Point Tracking Techniques for Solar Water Pumping System

Daoud A., Midoun A.

Electrical Power Quality and Utilisation. Journal

2009

Vol. 15, iss. 2

23--27

This paper describes new techniques of maximum power point (MPP) tracking for solar water pumping system. The latter system consists of a PV array, a DC/DC buck converter and a universal motor coupled to a centrifugal pump. A conventional hill climbing method is employed to seek the MPP using the motor-pump rotation speed or the pump outlet pressure information. Experimental results are presented and a comparison with conventional algorithm which requires both voltage and current sensors is provided.
