Patent

CA 2693109

A method and apparatus for anti-islanding of distributed power generation systems having an inverter comprising a phase locked loop (PLL), a phase shift generator for injecting a phase shift into the PLL during at least one sample period, and a phase error signature monitor for monitoring at least one phase error response of the PLL during the at least one sample period.

L'invention concerne un procédé et un appareil anti-îlotage de systèmes de production d'énergie répartis, comprenant un inverseur constitué d'une boucle à phase asservie, d'un générateur de déphasage destiné à injecter un déphasage dans la boucle à phase asservie pendant au moins une période échantillon, et d'un contrôleur de signature d'erreur de phase destiné à contrôler au moins une réponse d'erreur de phase de la boucle à phase asservie pendant ladite période échantillon au moins.
