Abstract: This paper analyzes operation problems of medium voltage switchgear cabinet in the electric power system. According to the international standards of IEC 61850, model the new arc protection device on the bus and analysize the relationship of abstract communication serivce inferface (ACSI) mapping to manufacturing message specification (MMS). Finally, MMS PDU formation and decoding are described specifically based on ASN.1 encoding rules.

Abstract: This paper presents a model designing and simulation realization of arc protection system based on GOOSE (Generic Object Oriented Substation Event) .It is proposed to fully use the logical node GGIO (Generic Input and Output) of IEC61850 in the modeling of intelligent electronic devices. The real-time data (data of arc intensity and loop circuit) are transferred by GOOSE message with time delay less than 4 ms. GOOSE message communications mechanism is introduced. Winpcap development packet is selected and the simulation program is written to transmit and capture the GOOSE messages.
