Title (EN) PRECISE REAL-TIME ADVANCED GRID MONITORING
(FR) SURVEILLANCE DE GRILLE AVANCÉE EN TEMPS RÉEL PRÉCISE
Abstract:
(EN) A hardware-synchronised integrator for grid monitoring that eliminates the offset in the determination of the grid frequency. The equation for the integrator is: y(n) = y(n-1) plus a term in Ts, the sampling time. The hardware synchronisation involves the use of Ts-act rather than an estimate Ts. An inverter is described which includes the hardware-synchronised.
(FR) L'invention concerne un intégrateur à synchronisation matérielle de surveillance de grille qui élimine le décalage dans la détermination de la fréquence de grille. L'équation pour l'intégrateur est : y(n) = y(n-1) plus un terme en Ts, le temps d'échantillonnage. La synchronisation matérielle implique l'utilisation de T s-act plutôt qu'une estimation de Ts. L'invention concerne également un onduleur qui comprend l'intégrateur à synchronisation matérielle.
