Modelagem e análise da proteção anti-ilhamento de geradores distribuídos térmicos e fotovoltaicos

This paper presents an analysis of the anti-islanding protection (AIP) functions behavior during islanded operation a distribution network section that contains simul- taneously distributed generators interfaced by inverters and directly connected to grid via synchronous generator. Through simulations carried out, it was verified tripping time traditional passive islanding detection is significantly affected when there are island. due existence synchronous, although weak, reference for photovoltaic generator, extending its operation. It also need greater care in parameterization AIP as well complementation more robust sensitive order ensure reliability security.
