Abstract
Methods and systems for islanding detection in power generators, particularly power converters. The present innovative methods can disconnect the power converter from the power distribution grid. Islanding detection can be performed by detecting the difference in resistive impedance between the islanded and un-islanded conditions, using an input-output power and input-output voltage correlation technique. The present methods can shut down the power converter instead of allowing it to continue running without connection to the grid, which will protect line-worker safety.
