| Abstract | An experimental study, on direct current photovoltaic pumping system test is undertaken on the
initially established test bed , applying the AIT TEST METHOD, to make comprehensive
evaluations of the two directly coupled PV pumping systems, a centrifugal pump system and a
reciprocating piston pump system, installed in the Energy Park of AIT. Both the steady state and
the daily performance tests have been committed for different water head operations.
The experimental studies concludes that the maximum steady state system efficiency is between
1.0% to 1.6% in the case of the centrifugal pump system, corresponding to the heads between
2 to 6 meters, and 1.5% to 4.1 % in the piston pump system with the similar insolation conditions
corresponding to the heads of 2 to 10 meters. These values are relatively lower to the typical
values of the same kind systems. The bottleneck of the system behavior lie in both the
degradation of component property and the mismatching between the PV panel and the motor pump sets. The regression models of the motors and pumps have been obtained through a series
component and complementary tests. The possible improvement measures have also been
proposed for these two pumping systems.
It also concludes that the AIT TEST METHOD of field testing of photovoltaic water pumping
system is practical and effective for application. The technical approach used, PV Pumping Test
Bed, can work efficiently under the normal weather conditions, however it still need to be
improved for more accurate evaluation of the pumping system performance. Further
modifications of the Test Bed have been proposed for future applications. |
