Objetivo
The aim of this paper is to analyze the example of one of the initial
projects developed according to the IEC 61850-8-1 standard and
have a look on what this is practically changing in term of products
and architecture of the substation automation system.
The example is then generalized with the observations made on
other projects in order to outline some general guidelines when
using this technology.
Objetivo
The project in example consisted in a new 400kV GIS
substation connected to a combined cycle power plant on one
side and to the Algerian transmission grid on the other side (04
Geradores e 02 Saídas de Linhas).
Some of the constraints and challenges included:
-Use and integrate qualified protection relays.
-Link with the Power Plant control system by a fully redundant
IEC 60870-5-104 link.
-Engineer the project within 6 months from order to Factory
Acceptance Tests, this was completed in january/2005.

Objetivo
Products:
The system is made of IEDs from five different suppliers with
different communication capabilities. The requirement for
qualified protection and metering IEDs has lead to the use of
legacy communication protocols for some of the products
since they were not available on IEC 61850 when the project
started.
Objetivo
• Logical Architecture (Not Physical Architecture):
Destaque
• Redundancy
A more delicate question concerns the management of the link
redundancy. This is not defined by the standard and several solutions
are currently proposed. The reconfiguration performance in case of a
failure of the main link is the key issue: few solutions enable to stay
compatible with the “4 ms” transfer time (traditional reference when
assessing performance for substation communications) between
IEDs. For instance the fast spanning tree is an algorithm defined by
the IEEE 803.2w standard to reach real time performance, however
its current implementation does not respect this constraint with a
typical architecture made of a ring with 20 different switches.IEC
61850.
Dúvidas
1. Qual o resultado dos Testes de aceitação em fábrica e campo?
2. Foi realizado testes de avalanche e qual foi a sua performance?
Conclusões
• IEC 61850 is a very exciting technology possibly driving a lot of
innovations. One needs to pay attention that this is still a young
one (thus theory and reality might differ) and more importantly
that this is only a base for the definition of a system.
• It will naturally reinforce the need for a robust system design
(architect mission) and the use of more advanced engineering
tools (configuration, simulation).
