Title:
SOLAR POWER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/256269
Kind Code:
A1
Abstract:
The present invention relates to a solar power system comprising: an arc detection device; a solar array; a connection panel; an inverter; and the like, and more specifically to a solar power system capable of analyzing sound waves generated from any one of a solar array, a connection panel, and an inverter to determine whether an arc is generated, so as to prevent fires or to provide early warning. The present invention randomly selects a sample of an arc extracted from a sound wave signal, and generates a single signal to generate an arc sound wave used for deep learning, thereby reducing costs and learning data generation time. In addition, the present invention has the effect of reducing errors in arc detection by determining whether the arc occurs in units of chunks in which frames are bound.
