摘要

太阳能光伏阵列在所有可能的领域都有指数级的应用，从几百瓦到兆瓦。在这种情况下，故障检测、分类和位置识别是太阳能光伏阵列高效运行和最大功率提取的主要目标。尽管已有许多算法为此目的而进行，但本文提出了一种新的PV故障实验研究方法，该方法通过获取所有模块电压(mv)，并借助于具有单个电压传感器的简单低成本继电器。本研究采用的故障包括开路(OC)、旁路二极管OC、短路(SC)和旁路二极管SC类型。在300-W (5×3)光伏阵列系统上实现了这些故障类型，并对其mv进行了计算和分析。所得结果在性质上是令人满意的，所提出的方法可以在广泛的光伏系统中实施。

Detection, Classification, and Location of Open-Circuit and Short-Circuit Faults in Solar Photovoltaic Array: An Approach Using Single Sensor

Solar PV arrays are exponentially employed in all possible spheres, ranging from a few hundred watts to megawatts. In this context, fault detection, classification, and location identification are the major objective for the efficient operation and maximum power extraction from the solar PV array. In spite of the numerous existing algorithms carried out for this objective, a new experimental study on the PV fault is put forward by obtaining all the module voltages (MVs), assisted by a simple low-cost relay with a single voltage sensor. Faults taken for this study are open-circuit (OC), bypass diode OC, short-circuit (SC), and bypass diode SC types. These fault types are implemented on a 300-W (5×3) PV array system and their MVs are obtained and analyzed. The obtained results are found to be satisfactory in nature and proposed methodology can be implemented in a wide range of the PV system.

期刊介绍： The IEEE Journal of Photovoltaics is a peer-reviewed, archival publication reporting original and significant research results that advance the field of photovoltaics (PV). The PV field is diverse in its science base ranging from semiconductor and PV device physics to optics and the materials sciences. The journal publishes articles that connect this science base to PV science and technology. The intent is to publish original research results that are of primary interest to the photovoltaic specialist. The scope of the IEEE J. Photovoltaics incorporates: fundamentals and new concepts of PV conversion, including those based on nanostructured materials, low-dimensional physics, multiple charge generation, up/down converters, thermophotovoltaics, hot-carrier effects, plasmonics, metamorphic materials, luminescent concentrators, and rectennas; Si-based PV, including new cell designs, crystalline and non-crystalline Si, passivation, characterization and Si crystal growth; polycrystalline, amorphous and crystalline thin-film solar cell materials, including PV structures and solar cells based on II-VI, chalcopyrite, Si and other thin film absorbers; III-V PV materials, heterostructures, multijunction devices and concentrator PV; optics for light trapping, reflection control and concentration; organic PV including polymer, hybrid and dye sensitized solar cells; space PV including cell materials and PV devices, defects and reliability, environmental effects and protective materials; PV modeling and characterization methods; and other aspects of PV, including modules, power conditioning, inverters, balance-of-systems components, monitoring, analyses and simulations, and supporting PV module standards and measurements. Tutorial and review papers on these subjects are also published and occasionally special issues are published to treat particular areas in more depth and breadth.
