Photovoltaic （PV） Array Fault Diagnosis Strategy Based on Optimal Sensor Placement
摘要
Abstract
Photovoltaic （PV） array output characteristics under fault conditions were simulated, the changing regularity of them was summarized. Fault diagnosis method based on branch current and PV module voltage detection was studied, three different voltage sensor placement methods were compared and the optimal sensors placement method was designed. PV array was equivalent to matrix, and weight matrix was established. This paper proposed a method of optimal voltage sensor placement based on covering all weight nodes. By the proposed method, a 3x3 PV array was researched, and voltage sensor characteristic values under different fault conditions were also measured. On the base of PV array fault diagnosis method, this paper also proposed maximum power point tracking （MPPT） strategy under shadow. Experimental results were presented to validate the proposed method.关键词
