Objetivo
Contribute as a Utility’s Automation system integrators
• identifying a common thread to interconnect
various systems together
• benefit from the offered services/standards
• suggested guideline for future expansion
Destaques
Modern substation integration, testing & commissioning
• becoming very complex
There is no right or wrong answer in the
design of substation automation
Destaques
Key to success
• listening to requirement of all involved parties
• design a system that meets everyone needs
Results
• quality substation automation
• uninterrupted service to customers
while reducing operation expenses
Destaques
Forcing complete interoperability between Control
centre(s) & substation had led to a situation of
obsolescence
Both end vendor(s) claims interoperability
both are stubborn to comply with each other
Utility is forced to compromise its
standard to meet vendor limitation
Destaques
First experience with substation automation using IEC 61850
“most of the initial promises could not be fulfilled”
DCS Vendors
• Not sharing
• system topology
• plug/play capability
• information models in IEDs
• IED configuration files (.idc/.scd)
Destaques
Factors delaying optimal substation automation
• lack of interoperability
• overlapping standards
• weak redundancy
• lack of common ‘vision’
Vendor’s limitation in adapting to Utility’s requirement
• over-Engineering
• availability
• channel redundancy
• PMR
Destaques
Needs for Conformance and Interoperability Test
IEC 61850 requires a complex conformance test system
• new standard with just a few manufacturers
• very complex
Benefits of conformance
• assuring interoperability
• ensuring reliability
• reducing risk
Destaques
Expansion Guideline
Considered for future substation expansion
• Reliability
• a system that meets Operation needs
• Compliance
• a system that complies with international
standard
• Interoperability
• an open system that can exchange data with
other systems
Destaques
Recommendations
• Precise Specification to prevent Over-Engineering
• Interoperability Certification
• Conformance Testing
• Share experience with other utilities
Dúvidas
Conclusões
The future seems to promise greater integration and data
sharing between devices with less manual configuration
effort at lower cost
Acquired data is highly useful for the real time operation
and monitoring of substations
Utility role to decide how to
benefit from the huge amount of
data to resolve the significant
challenge of growing demand &
achieve customer satisfaction
Respostas às questões do REP
• Questão: 1.7
Conformance and interoperability certification of devices is
recommended. Conformance certificates are available today, but no
interoperability certification is defined. Is it generally accepted, that
conformance testing of devices is not sufficient to guarantee
interoperability?
In general, it is considered that the conformity tests guarantee
the adherence to the norm, but does not guarantee its
interoperability.
Differences in the diverse implementations may exist.
Extensions to the standard are allowed by the norm.
