Abstract
Faults in PV array fields do not only affect the performance and services of the plant but may also lead to critical and detrimental situations. Although such faults change the electrical characteristics of the PV system, usually, they are not easily observed. Causes are the uncertainty of overall efficiency values, the limited number of measured operation data, and the lack of precise reference values, especially. A procedure for the detection of solar cell array faults is proposed, comparing actual to expected electrical parameters; accurate reference data being computed by a detailed PV circuit simulation program. Since the program delivers the whole IV curve, not only the maximum power point values can be checked but actual voltage and current under any operating conditions. An analysis of all faults, which may occur in PV fields, has been carried out for the development of comparison rules. >

Power rating of PV (photovoltaic) modules is realized at standard test conditions (1000 W/m/sup 2/ total irradiance, AM 1.5 spectral distribution in the plane of module, and 25 degrees C cell temperature). Design, monitoring, and check of specifications of PV modules and systems require prediction of module characteristics (maximum power, efficiency, V/sub mpp/, V/sub oc/, and I/sub sc/) under various conditions. A procedure for transformation of outdoor measurements or data sheet specifications...

On-site array power measurements are a very efficient way to determine mismatch conditions, cabling errors and ground faults as well as module failures or degradation. During the past 3 years the ESTI team has measured the array output of more than 10 large PV installations by scanning the I–V characteristics of the arrays, using a capacitor load. We present here some of these results as well as the methodology used to obtain I-V curves extrapolated to Standard Test Conditions from the actual sc...

This paper presents the latest versions of several models developed by the authors to predict short time-step solar energy and daylight availability quantities needed by energy system modelers or building designers. The modeled quantities are global, direct and diffuse daylight illuminance, diffuse irradiance and illuminance impinging on tilted surfaces of arbitrary orientation, sky zenith luminance and sky luminance angular distribution. All models are original except for the last one which is ...

A Pascal program, PVNet, has been developed at the Commission of the European Communities Joint Research Centre, Ispra, to model the electrical behaviour of solar cell interconnection circuits. The program calculates three-quadrant solar cell current-voltage (I–V) curves using a lumped parameter equivalent circuit model, combines them to obtain the resultant I–V curve of any interconnection circuit, and calculates the operating point of each circuit element, set by user-defined operating conditi...

A significant reason for performance loss is fault occurring in the Photovoltaic (PV) system. Nowadays, with the availability of intelligent control techniques the faults can be identified easily. To identify the fault, Artificial Neural network controller is designed. The power injected to the grid by the photovoltaic system is decreased due to the faults occurring in the system. Usually the fault occurs in Photovoltaic panel, Maximum Power Point Tracking controller (MPPT), Boost converter, inv...

Photovoltaic arrays are prone to various failures due to long-term work. In order to quickly and accurately diagnose the type of failure of the PV array and implement online monitoring of the PV array, this paper proposes the BP neural network for PV array fault diagnosis, and proposes a network search method when training BP neural network. And the K-cross-validation method is used to select the number of hidden layer nodes. The BP neural network fault diagnosis model designed and trained by th...

Abstract Over the last decade, research into photovoltaic (PV) technology has shifted from a race for the highest efficiency to the increase of the performance reliability in the field. A major part of current research activities focuses on the reliability of the installations and the guaranteed lifetime output through constant, solid and traceable PV plant monitoring. In this domain, several PV monitoring strategies for the early diagnosis of failures in grid-connected PV systems have been prop...

The American National Electric Code (NEC) requires the presence of a series-arc-fault-detector in any Photovoltaic installation operating at a voltage greater than or equal to 80V. Therefore, the presence of an accurate series-arc-fault detector that can detect series-arc-faults and discriminate them from Partial Shading (PS) is required. The work in this paper proposes an algorithm that can detect series-arc-fault and discriminate them from PS in total cross tied arrays. This algorithm is based...

Since the use of photovoltaics in the domestic and industrial sector is increasing, the reliability and safety of photovoltaic power generation systems is becoming more and more important. One of the crucial issues for safety is the formation of a hot spot, which can reach several hundred degrees Celsius in less than thirty minutes. For this reason, a fire may occur under prolonged exposure. However, a method for hot-spot detection during operation, based solely on current-voltage characteristic...

Since photovoltaic (PV) arrays are outdoor components and may experience harsh environmental conditions, early fault detection in such systems is vital. High capacity PV farms are generally established in a wide area and so having an efficient and cost effective monitoring system for them is a challenge. This paper is aimed to find the optimal number and scheme of the required measurement units to have a desirable monitoring system. To this end, a neural network (NN) based fault detection method...

Abstract Aiming at monitoring photovoltaic (PV) systems, evaluating the degree of fault and locating the fault automatically under different outdoor conditions, this paper discusses a new procedure of fault detection and evaluation of fault degree of the PV system. For the PV array connected by PV modules in series and parallel, each string shares the same voltage. The value of current can be used to identify the underperformed strings. In addition, considering the non-stationary stochastic char...
