Title (EN) VOLTAGE REGULATION FOR MULTI-PHASE POWER SYSTEMS
(FR) RÉGULATION DE TENSION POUR SYSTÈMES D'ALIMENTATION POLYPHASÉS
Abstract:
(EN) A power system can include a first tap changer for a first regulated transformer, where the first tap changer has a plurality of first positions. The power system can also include a second tap changer for a second regulated transformer, where the second tap changer has a plurality of second positions. The power system can further include at least one first instrument transformer coupled to the first regulated transformer. The power system can also include at least one second instrument transformer coupled to the second regulated transformer. The power system can further include a controller coupled to the at least one first instrument transformer and the at least one second instrument transformer, where the controller adjusts the first tap changer to a first adjusted position among the first positions based on the first measurements of the first regulated transformer and the second measurements of the second regulated transformer.
(FR) L'invention concerne un système d'alimentation pouvant comprendre un premier changeur de prise pour un premier transformateur régulé, le premier changeur de prise présentant une pluralité de premières positions. Le système d'alimentation peut également comprendre un second changeur de prise pour un second transformateur régulé, le second changeur de prise présentant une pluralité de secondes positions. Le système d'alimentation peut en outre comprendre au moins un premier transformateur de mesure couplé au premier transformateur régulé. Le système d'alimentation peut également comprendre au moins un second transformateur de mesure couplé au second transformateur régulé. Le système d'alimentation peut en outre comprendre un dispositif de commande couplé audit premier transformateur de mesure et audit second transformateur de mesure, le dispositif de commande réglant le premier changeur de prise à une première position réglée parmi les premières positions sur la base des premières mesures du premier transformateur régulé et des secondes mesures du second transformateur régulé.
