The document provides an introduction to substation automation and IEC 61850. It discusses the evolution from conventional to modern substation automation, including distributed intelligent electronic devices (IEDs) that communicate over an Ethernet network. It describes the key aspects of IEC 61850, including the data model approach, use of logical nodes, and engineering process that uses the Substation Configuration Description Language (SCL). The standard aims to provide interoperability, long-term stability, and flexibility in function allocation.

Interoperability The ability for IEDs from one or several manufacturer to exchange information and use the information for the their own functions. Free allocation The standard shall support different philosophies and allow a free allocation of functions e.g. it must work equally well for centralized (RTU like) or decentralized (SCS like) systems.
