Abstract: front page image
(EN)A reactive power compensation apparatus of the present invention comprises: a sensing unit for sensing the power factor of a three-phase power supply path; a reactive compensation switching unit for adjusting the number of capacitors coupled to each phase of the three-phase power supply path and for compensating reactive power of the power supplied to the three-phase power supply path; and a switching control unit for controlling a switching operation of the reactive compensation switching unit according to the sensed power factor, wherein the reactive compensation switching unit may comprise compensation capacitors connecting between the power supply paths of the respective phases and a neutral line; a semi-conductor switch for switching the connection of the compensation capacitors; and two or more unit control modules having a harmonic reduction reactor that is connected in series with the semi-conductor switch.
(FR)La présente invention concerne un appareil de compensation de puissance réactive qui comprend : une unité de détection pour détecter le facteur de puissance d'un chemin d'alimentation électrique triphasée; une unité de commutation de compensation réactive pour régler le nombre de condensateurs couplés à chaque phase du chemin d'alimentation triphasée et pour compenser la puissance réactive de la puissance fournie au chemin d'alimentation électrique triphasée; et une unité de commande de commutation pour commander une opération de commutation de l'unité de commutation de compensation réactive en fonction du facteur de puissance détecté, l'unité de commutation de compensation réactive pouvant comprendre des condensateurs de compensation se connectant entre les chemins d'alimentation électrique des phases respectives et une ligne neutre; un commutateur à semi-conducteur pour commuter la connexion des condensateurs de compensation; et au moins deux modules de commande d'unité comprenant une bobine de réactance de réduction des harmoniques qui est connectée en série avec le commutateur à semi-conducteur.
