The Use of PLL Stability for Islanding Detection

Description:

Quasi-active islanding detection metehod that does not inject distortions into grid via the output of the converter, but rather relies on the stability of the PLL which, with the proposed implementation, inherently senses a grid disconnect and starts to oscillate.
