中文摘要

本文提出了一种基于量子概率模型理论的光伏系统串联电弧故障检测算法。该算法通过计算光伏面板电流的修正Tsallis熵来判断电弧的存在。利用熵值变化,算法能够有效区分混沌电流特征的电弧状态与正常运行状态。

English Abstract

This paper presents a series arc-fault detection algorithm for photovoltaic (PV) systems, which relies on the quantum probability model theory. The algorithm determines the presence of the arc by calculating the modified Tsallis entropy of the PV panel current. Based on the calculated entropy, the algorithm is able to differentiate an arc state (when the current variations are chaotic) from a no-a...
