Paper Abstract

In this paper, a new fault diagnosis approach for the photovoltaic array, which is based on infrared and visible image fusion technique, is proposed. Firstly, the temperature difference and infrared characteristics are analyzed, and then the features of both infrared image and visible image are extracted. By comparing the features of infrared image with those of visible image, the abnormal operating regions covered with something are distinguished. A fuzzy fault diagnosis approach is introduced and implemented for other regions detected in infrared image but none in visible image. Experimental results show that the proposed approach is feasible and effective.
