Abstract

Abstract: In order to reduce the facility cost of merging units and enhance their intelligence and versatility, an improved intelligent merging unit using multi-ARM for smart substations is proposed. The design procedure of its hardware and software is presented in detail. Flexible modular patterns are utilized for the whole framework design, and fiber interfaces are used to establish the bi-directional fast Ethernet communications between the system and other intelligent electronic devices. With the help of high-speed network communication, standard sampled values and GOOSE messages can be sent and received reliably based on IEC 61850. In addition, the software flows of critical modules such as sampling and switch-in/switch-out control modules are illustrated. The test results on the transmission of sampled values and GOOSE messages demonstrate that the equipment works reliably and steadily, and it shows high performances of real-time, dependability and communication speed, which greatly satisfies the needs of smart substations.

Key words: smart substation, ARM, IEC 61850, sampled value, GOOSE, merging unit, intelligent electronic devices
