Title
(EN) SYSTEMS AND METHODS FOR OPERATING GENERATORS BASED ON GENERATOR STEADY STATE STABILITY LIMITS
(FR) SYSTÈMES ET PROCÉDÉS PERMETTANT DE FAIRE FONCTIONNER DES GÉNÉRATEURS SUR LA BASE DE LIMITES DE STABILITÉ D'ÉTAT STABLE DE GÉNÉRATEUR
Abstract
(EN) A generator control computer device for operating at least one generator attached to a grid is provided. The generator control computer device includes at least one processor in communication with at least one memory device. The generator control computer device is configured to receive, from at least one sensor, a plurality of sensor readings representing one or more conditions of the at least one generator, calculate a current grid impedance of the grid based on the plurality of sensor readings, determine a steady state stability limit for the at least one generator based on the current grid impedance, and adjust operation of the at least one generator based on the determined steady state stability limit.
(FR) La présente invention concerne un dispositif informatique de commande de générateur permettant de faire fonctionner au moins un générateur rattaché à un réseau. Le dispositif informatique de commande de générateur comprend au moins un processeur en communication avec au moins un dispositif de mémoire. Le dispositif informatique de commande de générateur est configuré pour recevoir, en provenance d'au moins un capteur, une pluralité de lectures de capteur représentant un ou plusieurs états du ou des générateurs, calculer une impédance de réseau actuelle du réseau sur la base de la pluralité de lectures de capteur, déterminer une limite de stabilité d'état stable pour le ou les générateurs sur la base de l'impédance de réseau actuelle, et régler le fonctionnement du ou des générateurs sur la base de la limite de stabilité d'état stable déterminée.
