What is intelligent system for detecting faults in photovoltaic fields?

An intelligent system for detecting faults in photovoltaic fields is described in . This system provides an estimation of the instant power production of the PV field in normal functioning. The estimated power is compared with the measured power, and an alarm signal is generated if the difference overcomes a threshold.

Can grid-connected photovoltaic systems improve reliability and scalability?

Our study’s findings hold significant implications for real-world applications in grid-connected photovoltaic (PV) systems. They enhance fault diagnosis accuracy, operational efficiency, and scalability, contributing to maintaining PV systems reliability, reducing downtime, and optimizing maintenance schedules.

What parameters are used to train an Ann in a photovoltaic system?

In , two parameters such as string current (upper and lower sides) and total array current, are used as the input to train the ANN, and each fault is assigned a fault number, which is used as the target data. In fact, these two parameters are not sufficient to accurately discriminate all major types of faults in photovoltaic systems.

What is a fault detection method for photovoltaic module under partially shaded conditions?

A fault detection method for photovoltaic module under partially shaded conditions is introduced in . It uses an ANN in order to estimate the output photovoltaic current and voltage under variable working conditions. The results confirm the ability of the technique to correctly localise and identify the different types of faults.

How can low-cost edge devices improve grid-connected photovoltaic systems?

Provided by the Springer Nature SharedIt content-sharing initiative Early fault detection and diagnosis of grid-connected photovoltaic systems (GCPS) is imperative to improve their performance and reliability. Low-cost edge devices have emerged as innovative solutions for real-time monitoring, reducing latency, and improving response times.

What are the disadvantages of detecting faults in photovoltaic fields?

The main drawback of this method is that it is of high cost. An intelligent system for detecting faults in photovoltaic fields is described in . This system provides an estimation of the instant power production of the PV field in normal functioning.
