Abstract :
Performances of induction-motor-based residential photovoltaic water pump system (IMRPWPS) with low DC voltage input (24 V DC) are tested in laboratory under four different operation modes, such as efficiency of DC-AC converter with high-frequency DC-DC stage, machine-pump and overall system. By analysis of these experiment results, it is discovered that the operation head and voltage-frequency ratio of motor (U/f) have significant effect on the performances of IMRPWPS besides the configuration of system components. And the minimum unit water cost may not be reached only by the control strategy of maximum output power of the system. Hence, as for a certain site, the proper selection of characteristics of converter and motor-pump and optimal ratio of U/f is significantly important to improve the economic performance of the system.
