Abstract

In order to promote the practical application of IEC61850 in status monitoring (SM) system of smart substation, combined with the function requirement of smart substation SM and the characteristics of SF6 circuit breaker state on-line monitoring, the model for actual intelligent electronic device (IED) of SF6 circuit breaker SM is established in terms of the information modeling technology of IEC61850, which is described in substation configuration description language (SCL). Besides, this paper analyses the buffered report control block, file transfer model and their service. A communication method between SM intelligent electronic devices is proposed which the SM data is mapped to GOOSE message to transfer, at last the software processing of GOOSE message is analyzed in detail.
