Multicast management method and device for intelligent substation process level

The invention provides a multicast management method and a device for an intelligent substation process level. The multicast management method includes the steps of according to a scheduled rule, performing static multicast configuration by utilizing a static multicast technology to generate a static multicast configuration table; and forwarding multicast of a media access control (MAC) address registered in the static multicast configuration table according to a configuration port. According to the multicast management method and the device for the intelligent substation process level, the multicast technology is adopted, the static multicast configuration table is generated in advance, the forwarding of the registered multicast at a designated port is achieved according to the static multicast configuration table, which multicast addresses are received by each intelligent electronic device (IED), namely, which merging unit (MU) are associated with the IED is quite intuitive, when the designated port receive
