Efficiency analysis of PV inverter – adjustable speed drive system

This project entails efficiency analysis of a distributed generation system consisting of Photovoltaic (PV) – Inverter system as the renewable source connected to a network of Adjustable Speed Drives (ASDSs) as the load. A small-scale laboratory of the Photovoltaic, Inverter, ASDSs and Loads system were used in this research. Two power supplies from PV and grid were connected to three ASDSs which powered three separate induction motors. Experiments were carried out. Measurements were recorded from which the interaction between the source and the load in this system may further be analyzed. Analysis of the result was carried out in which results of both experiments were compared. At the end of the research project, the worst and best case operating scenarios were indentified from which base-line information for optimum operating conditions is achieved
