An approach for fault detection and location in solar PV systems
Based on the fault in a single string or multi string, the line-line faults are categorised as intra-string (e.g. faults F 1, F 2 and F 3 in Fig. 2) or cross-string (e.g. fault F 4 in Fig. 2). The occurrence of a line-line fault results in topological changes within a PV array due to partial or total bypassing of modules within strings caused by line-line short …
