Secure layer 2 tunneling over IP for GOOSE-based logic selectivity

Logic Selectivity immensely reduces both number of outages and their duration in the distribution network. IEC 61850 can be applied for standard implementing of Logic Selectivity in which Generic Object Oriented Substation Events (GOOSE) messages should be exchanged between intelligent field devices over the Internet. However, information security and automation requirements must be noted in order to ensure secure and accurate operation of Logic Selectivity. This paper describes lab setups for analyzing functional and non-functional characteristics of GOOSE-based Logic Selectivity. Layer 2 tunneling over IPsec is proposed for GOOSE communication over 4G Internet. Data integrity and confidentiality are achieved via IPsec in Transport mode. Furthermore, communication impact on Logic Selectivity performance are investigated by the software tool measuring communication network quality.
