About this chapter
This chapter describes the functions and protocols used on the interfaces to the
substation automation and substation monitoring buses. The way these work, their
setting parameters, function blocks, input and output signals and technical data are
included for each function.
17.1 Overview
Each IED is provided with a communication interface, enabling it to connect to one or
many substation level systems or equipment, either on the Substation Automation (SA)
bus or Substation Monitoring (SM) bus.
Following communication protocols are available:
• IEC 61850-8-1 communication protocol
• IEC 61850-9-2LE communication protocol
• LON communication protocol
• SPA or IEC 60870-5-103 communication protocol
• DNP3.0 communication protocol
Theoretically, several protocols can be combined in the same IED.
17.2 IEC 61850-8-1 communication protocol
17.2.1 Introduction
The IED is equipped with single or double optical Ethernet rear ports (order
dependent) for IEC 61850-8-1 station bus communication. The IEC 61850-8-1
communication is also possible from the optical Ethernet front port. IEC 61850-8-1
protocol allows intelligent electrical devices (IEDs) from different vendors to exchange
information and simplifies system engineering. Peer-to-peer communication according
to GOOSE is part of the standard. Disturbance files uploading is provided.
