An optimal multi-degree open-circuit faults diagnostic algorithm for photovoltaic system

摘要

In this paper, an optimal multi-degree open-circuit faults diagnostic algorithm, for improving condition monitoring ability of photovoltaics, has been proposed. This algorithm combines output parameters and characteristic impedance of PV-system under low frequency domain in simplified manner. The feasibility and accuracy of the method has been proven through simulation using Siemens-SM100-12.
