In order to realize the interoperability between the smart terminal units (STUs) for distributed feeder automation (FA) and ensure the communication safety between them, this paper proposes an IEC 61850 communication mapping scheme using built-in secure extensible messaging and presence protocol （XMPP） and generic object oriented substation event (GOOSE) based on user datagram protocol (UDP). The security protection scheme based on Hash obtain random subset （HORS） one-time signature is used to ensure the communication safety of GOOSE messages. The agent-based distributed FA test system is developed with the STUs.The test results show that the scheme can meet the requirements of the quick distributed FA.
