Abstract
The standard IEC 61850 has been used in Brazil since 2008 to systematize the parameters of data communication regarding substation automation in an open, interoperable framework. Most electrical projects, which apply the standard IEC 61850, take only GOOSE message and MMS through the station bus. However, the standard recommends a second bus, named process bus. In 2022 the application of process bus is limited to pilot-project on electrical utility only to learn about its use and impact on substation operation. The analysis of technical reports concluded that there is no engineering approach to design a substation automation project within the station and process bus. Therefore, this paper aims to introduce a procedure to design a fully digital substation according to standard IEC 61850. The approach presented has been applied in a 15 kV substation.
