PROCEDE ET DISPOSITIF DE DETECTION D'ARC ELECTRIQUE DANS UNE INSTALLATION PHOTOVOLTAIQUE

摘要

Method of detecting an electric arc in a photovoltaic installation, it comprises the following steps: . - measuring (E6) values of voltage in at least one location of the electrical circuit of the photovoltaic installation; . - digitizing (E8) the voltage values measured so as to form a data sampling x; . - calculating (E10) an estimation value y of presence of an electric arc on the basis of a statistical calculation on the data sampling and then taking into account a forget factor phi; . - comparing (E12) the estimation value y of the presence of an electric arc with a threshold value so as to deduce therefrom the presence or otherwise of an electric arc within the photovoltaic installation.
