between IEDs

GOOSE = Generic Object Oriented Substation

GOOSE is used to broadcast events to peer

IEDs in a substation

Can in principle transmit any kind of process

data between the IEDs

IEC 61850 communication servicesThe mechanism of GOOSE messages

Without any changes, the GOOSE-message is repeated

with Tmax until the next event / change.

In case of a information-change, the GOOSE-message will be repeated within Tmin.

The repetition frequency is lowered until Tmax is reached.

Station interlockingHardwired interlocking bus

IEC 61850-8-1

Hardwired Interlocking Bus

Advantages Disadvantages

Features

The distribution of information requires many cables and auxiliary

contacts

No special tools or training are required to test and maintain

hardwired installations

Hardwired installations can be extended or commissioned piece by

piece, with minimal or no modification of existing IED

configurations

If, for example, position indications for interlocking are directly

distributed via the primary equipment’s auxiliary contacts, the

number of devices in the signal change is minimized, which

reduces the risk of failure.

© ABB Group


Station interlockingIEC 61850 interbay bus (GOOSE)

IEC 61850-8-1

GOOSE

Generic Object Oriented Substation

Event

Features

Reduction of copper cabling between panels

All GOOSE data is continuously supervised, allowing the

immediate initiation of remedial actions in case of failure,

increasing the availability of the substation

Fewer in- and outputs are required in the IEDs and auxiliary relays

The selection of signals to be exchanged can be modified easily

without needing to change the inter-panel cabling

Hardwired signal exchange for station interlocking usually

introduces an external signal voltage to the panels, posing a

potential hazard. GOOSE communication eliminates this risk.

The transmission speed of GOOSE signal exchange matches or

outperforms conventional signal distribution

IED B (outgoing feeder) detects a fault,

issues an opening command to its

breaker and starts the breaker

failure protection

The breaker of the outgoing feeder fails to

open and after a set time delay the

breaker-failure protection in IED B

sends a BFP trip command to IED A as

a GOOSE message

After receiving the GOOSE message IED

A issues an opening command to the

incoming feeder breaker and the fault is

cleared

Introduction to process busWhat is process bus?

• IEC 61850 describes all

communication in the

substation

• The station bus transmits

information between the

bay level IEDs, and

between the station level

and the bay level

• The process bus connects

the process to the bay

level

What is IEC61850-9-2 process busProcess bus

• Optical Ethernet network

between primary

equipment and protection

and control IEDs

• Process bus replaces

parallel copper cabling with

a few fiber optics

• Isolation of primary process

through optical cabling

• Eliminates negative impact

of long copper cables

• Compliant with IEC 61850,

the standard in substation

communication

What is IEC61850-9-2 process busProcess bus for sampled analogue values

• International standard

IEC 61850-9-2

• Standardized distribution of

sampled analog values from

merging units to protection

and control IEDs, as well as

revenue meters

• All telegrams contain quality

information about the status

of sensor and merging unit

• Suitable for all applications

from protection to metering

and power quality

• Implementation follows the

guideline from UCA
