Abstract:
(EN) An overcurrent protection method, comprising the following steps: sampling an input current provided by the direct current side (S10); filtering the sampled current (S11); determining whether the filtered current is larger than a threshold current (S12); if the filtered current is larger than the threshold current, sending an overcurrent control signal to an inverter (S14), so as to control the current outputted by the inverter to a permanent magnet synchronous motor. The invention enables precise discovery of an overcurrent of a permanent magnet synchronous motor, and timely control of the overcurrent, thereby guaranteeing the safety of the permanent magnet synchronous motor when an overcurrent occurs.
(FR) Un procédé de protection contre les surintensités comprend les étapes suivantes consistant à : échantillonner un courant d'entrée fourni par le côté courant continu (S10) ; filtrer le courant échantillonné (S11) ; déterminer si le courant filtré est supérieur à un courant de seuil (S12) ; si le courant filtré est supérieur au courant de seuil, envoyer un signal de commande de surintensité à un onduleur (S14), de façon à commander le courant délivré par l'onduleur à un moteur synchrone à aimants permanents. L'invention permet une découverte précise d'une surintensité d'un moteur synchrone à aimants permanents, et une commande opportune de la surintensité, garantissant ainsi la sécurité du moteur synchrone à aimants permanents lorsqu'une surintensité se produit.
(ZH) 一种过流保护方法,包括以下步骤:对直流侧提供的输入电流进行采样(S10);对采样后的采样电流进行滤波(S11);判断滤波后的滤波电流是否大于阈值电流(S12);若所述滤波电流大于所述阈值电流,发出过流控制信号至逆变器(S14),以控制所述逆变器对永磁同步电机输出的电流。实现了精确地发现永磁同步电机的过流现象,并及时对过流现象做出控制处理,从而保障了过流产生时永磁同步电机的安全。
