Title (EN) OVERCURRENT PROTECTION METHOD, CONTROL SYSTEM AND STORAGE MEDIUM FOR BRIDGE ARM CURRENT
(FR) PROCÉDÉ DE PROTECTION CONTRE LES SURINTENSITÉS, SYSTÈME DE COMMANDE ET SUPPORT DE STOCKAGE POUR COURANT DE BRANCHE DE PONT
(ZH) 桥臂电流过流保护方法、控制系统及存储介质
Abstract:
(EN) An overcurrent protection method, control system and storage medium for bridge arm current of a flexible direct current transmission system. The method comprises: acquiring a bridge arm current (S101); processing the bridge arm current to obtain a current effective value and a current instantaneous value (S102); and protecting the bridge arm current when the current effective value is greater than a first set threshold and the current instantaneous value is greater than a second set threshold (S103).
(FR) L'invention concerne un procédé de protection contre les surintensités, un système de commande et un support de stockage pour un courant de branche de pont d'un système de transmission de courant continu flexible. Le procédé consiste à : acquérir un courant de branche de pont (S101) ; traiter le courant de branche de pont pour obtenir une valeur efficace de courant et une valeur instantanée de courant (S102) ; et protéger le courant de branche de pont lorsque la valeur efficace de courant est supérieure à un premier seuil défini et que la valeur instantanée de courant est supérieure à un second seuil défini (S103).
(ZH) 一种柔性直流输电系统的桥臂电流过流保护方法、控制系统及存储介质,该方法包括获取桥臂电流(S101);对桥臂电流进行处理,得到电流有效值和电流瞬时值(S102);当电流有效值大于第一设定阈值,且电流瞬时值大于第二设定阈值时,对桥臂电流进行保护(S103)。
