Title (EN) PROTECTION SYSTEM FOR LIMITING THE IMPACT OF THE DISRUPTIONS OF AN EXTERNAL ELECTRICAL NETWORK ON THE LOCAL NETWORK OF A SITE CONNECTED TO THE EXTERNAL NETWORK
(FR) SYSTEME DE PROTECTION POUR LIMITER L'IMPACT DES PERTURBATIONS D'UN RESEAU ELECTRIQUE EXTERNE SUR LE RESEAU LOCAL D'UN SITE BRANCHE SUR LE RESEAU EXTERNE
Abstract:
(EN) The invention relates to a protection system for limiting the impact of the disruptions of an external urban or industrial electrical network (3) on a local electrical network (1) of a site that is connected to the external network (3) and which comprises at least one local electric power source, referred to as "local source (6)" connected to the local network (1) and capable of injecting the surplus electric power into the external network (3), the protection system comprising a synchronous machine (9) connected to the local network (1) which is in turn connected to the external network (3) via a choke (10), referred to as "line filter choke", characterised in that the protection system comprises at least one local choke (13) that is associated with the local source (6) and connected to the local network (1) between the aforementioned local source (6) and the synchronous machine (9).
(FR) Système de protection pour limiter l'impact des perturbations d' un réseau électrique urbain ou industriel externe (3) sur un réseau électrique local (1) d'un site qui est connecté au réseau externe (3) et qui comprend au moins une source locale d'énergie électrique, dite « source locale (6) » branchée sur le réseau local (1) et pouvant injecter l'excédent d'énergie électrique dans le réseau externe (3), le système de protection comprenant une machine synchrone (9) branchée sur le réseau local (1) qui est lui- même branché sur le réseau externe (3) par l'intermédiaire d'une self (10), dite « self réseau », caractérisé en ce que le système de protection comprend au moins une self locale (13) qui est associée à la source locale (6) et qui est branchée sur le réseau local (1) entre la susdite source locale (6) et la machine synchrone (9).
