Abstract[English]
An on/off-grid switching control method. During on/off-grid switching control, when detecting a mains power outage, a power conversion system sends a turn-off control signal to a switching device to control the switching device to disconnect a connection between the mains power and a load, and switches to an off-grid operation mode only when receiving a turn-off completion signal sent by the switching device. The turn-off completion signal and the turn-off control signal for on/off-grid switching control are level signals having different voltage amplitudes, or each comprises at least one of a pulse signal and an edge signal.[French]
L'invention concerne un procédé de commande de commutation connecté/hors réseau. Pendant une commande de commutation connecté/hors réseau, lors de la détection d’une panne d’alimentation secteur, un système de conversion d’énergie envoie un signal de commande d’ouverture à un dispositif de commutation afin de commander audit dispositif de commutation de déconnecter une connexion entre l’alimentation secteur et une charge, et commute vers un mode de fonctionnement hors réseau uniquement lors de la réception d’un signal d’achèvement d’ouverture envoyé par le dispositif de commutation. Le signal d’achèvement d’ouverture et le signal de commande d’ouverture destinés à la commande de commutation connecté/hors réseau sont des signaux de niveau ayant des amplitudes de tension différentes, ou comprennent chacun au moins l’un parmi un signal d’impulsion et un signal de front.[Chinese]
一种离并网切换的控制方法，在控制离并网切换的过程中，功率转换设备在检测到市电掉电时，会向开关设备发送关断控制信号以控制开关设备断开市电与负载之间的连接，并在接收到开关设备发送的关断完成信号后，才会切换至离网运行模式。用于进行离并网切换控制的关断完成信号和关断控制信号为具有不同电压幅值的电平信号，或者二者包括脉冲信号和边沿信号中的至少一种。
