AI Technical Summary

Technical Problem

Arcing caused by poor contact in photovoltaic power generation systems is difficult to extinguish on its own and can easily lead to fires. Existing technologies lack effective detection methods.

Method used

By acquiring the DC and AC components of the current signal, the presence of arcing in the circuit is determined using a target arcing detection model. The model includes a clustering model or a neural network model, which is combined with the characteristics of the current signal for determination.

Benefits of technology

This enables timely detection of arcing, improves circuit safety, and avoids fire risks.
