Abstract
A method for communication in an energy automation network having a number of substations, each including energy automation component(s) and an internal communication network for message exchange. The communication networks of the substations are interconnected for message exchange via a public network without multicast support. Each energy automation component may include an application for controlling a communication unit, wherein messages according to IEC 61850 can be exchanged between applications of a common group which includes energy automation components of at least two substations. A first application of a particular group of applications transmits a message to second application(s) of the same group via the substation communication network and/or a public network. Tunnels that encapsulate GOOSE messages may be used to allow an overlay network for transmission of GOOSE messages via a public network without multicast support. The logical groupings of applications may therefore define separate, logical communication networks.
