ABSTRACT: Most of
the photo voltaic (PV) arrays often work in harsh outdoor environment, and
undergo various faults, such as local material aging, shading, open circuit,
short circuit and so on. The generation of these faults will reduce the power
generation efficiency, and when a fault occurs in a PV model, the PV model and
the systems connected to it are also damaged. In this paper, an on-line
distributed monitoring system based on XBee wireless sensors network is
designed to monitor the output current, voltage and irradiation of each PV module, and the temperature and the irradiation of the environment. A simulation PV module model is established, based
on which some common faults are simulated and fault training samples are
obtained. Finally, a memetic algorithm optimized Back Propagation ANN fault
diagnosis model is built and trained by the fault samples data. Experiment result
shows that the system can detect the common faults of PV array with high
accuracy.
