Characteristics of PV Short Circuit Faults Through Experiment with Line-Line Faults in PV Arrays

نویسندگان

چکیده

The rapid development of the solar industry over past several years has expanded significance photovoltaic (PV) systems. Fault analysis in arrays is a fundamental task to increase reliability, efficiency, and safety PV If no fault detected, it may reduce power generation, accelerate system aging, risks fire hazards. In this study, we considered line–line through verification experiments for hazard analyzed accident characteristics improve electrical This paper presents comparison regarding location accident, use blocking diodes, inverter operation. String protection systems without diodes should be designed considering current acceptable ratings all facilities path, from combiner box module. addition, array line-line include short-circuit back feed based on point. These currents contribute accidents with strong arcs

Nowadays, Distributed Generation (DG), especially PV systems as a new source of power absorbed a high percentage of investment. Fault Detection and analysis in solar photovoltaic (PV) arrays are important issues to increase reliability, efficiency and safety in PV arrays. Due to PV’s non-linear characteristics, current-limiting nature, high fault impedances, low irradiance condi...

Continual On-Line Diagnosis of Hybrid Faults

An accurate system-state determination is essential in ensuring system dependability. An imprecise state assessment can lead to catastrophic failure through optimistic diagnosis, or underutilization of resources due to pessimistic diagnosis. Dependability is usually achieved through a fault detection, isolation and reconguration (FDIR) paradigm, of which the diagnosis procedure is a primary com...

Reconfiguring Arrays with Faults Part I: Worst-Case Faults

In this paper we study the ability of array-based networks to tolerate worst-case faults. We show that an N × N two-dimensional array can sustain N1− worst-case faults, for any fixed > 0, and still emulate T steps of a fully functioning N × N array in O(T + N) steps, i.e., with only constant slowdown. Previously, it was known only that an array could tolerate a constant number of faults with co...

Reconnguring Arrays with Faults Part I: Worst-case Faults

In this paper we study the ability of array-based networks to tolerate worst-case faults. We show that an N N two-dimensional array can sustain N 1? worst-case faults, for any xed > 0, and still emulate a fully functioning N N array with only constant slowdown. Previously it was known only that an array could tolerate a constant number of faults with constant slowdown. We also show that if faul...

On-line Detection of Faults in Carry-Select Adders

This paper proposes an architecture for implementing a self-checking 4-bit carry select adder that can be extended to any n-bit addition. The overhead is directly proportional to the number of transistors in the adder.
