Title
(EN) VIRTUAL SYNCHRONOUS GENERATOR WITH ACTIVE DAMPING
(FR) GÉNÉRATEUR SYNCHRONE VIRTUEL À AMORTISSEMENT ACTIF
Abstract
(EN)
The invention relates to a method for controlling a power generating unit such as a wind turbine which is configured as a virtual synchronous machine. Capacitor voltage signals obtained from voltage measurements of output capacitors are filtered in order to reduce a magnitude of an impedance peak and/or shift the impedance peak where the impedance peak is present in an impedance characteristic of the output of the power generating unit. Filter compensated voltage signals obtained from the output capacitors are combined with a voltage magnitude reference to obtain filtered capacitor voltage signals used for controlling the line side converter and thereby affect the impedance peak in a desired way.

L'invention concerne un procédé de commande d'une unité de production d'énergie telle qu'une éolienne qui est configurée comme une machine synchrone virtuelle. Des signaux de tension de condensateurs obtenus par mesures de tension de condensateurs de sortie sont filtrés afin de réduire une amplitude d'un pic d'impédance et/ou décaler le pic d'impédance où le pic d'impédance est présent dans une caractéristique d'impédance de la sortie de l'unité de production d'énergie. Des signaux de tension compensés par filtre provenant des condensateurs de sortie sont combinés à une référence d'amplitude de tension de manière à obtenir des signaux de tension de condensateurs filtrés servant à commander le convertisseur côté ligne et influer ainsi sur le pic d'impédance d'une manière souhaitée.
