Supervision and fault detection in PV System

Abstract

Recently, the scientific research has focused on the exploitation of renewable energy sources due to they are clean, environmentally friendly, renewable and cannot be depleted. The efforts of scientists and researchers in this field have been about access to multiple methods of exploitation all types of renewable energy to provide the necessary energy to meet human varying needs. Indeed, these efforts have been fruitful as scientists and researchers have reached the possibility of using (wind energy, potential energy of running water and solar heat and light from the sun) to produce several types of energy the most important of which is electric energy, the most important of which is electric energy. The solar energy is distinguished from the rest of the renewable sources by its regular presence in all places. Therefore, the greatest interest is the use of this energy to produce electricity. This was achieved through the establishment of a photovoltaic system in which solar energy is converted into electric energy. In order to achieve the quantitative production of electricity it is necessary to establish photovoltaic fields on large areas requires large amount of electrical cables and wires exposed to damage may caused by weather or rodents

which lead to a lot of faults are difficult to detect and determine its source and this causes large parts of the field being stopped of bumping energy and this lead to a large losses in the amount of energy extracted.

This has enabled the researcher to design a proposed system for the immediate detection of faults and locating them by wireless fault detection and diagnosis system to avoid wiring fault. This system can reduce the time of repair and losses energy and prevent the aggravation of the faults that expose the PV arrays and the whole PV system to damage if not repaired.
