that support the fluid interchange of multi-vendor devices
IEC 61850 Global2019
HELINKSThis Presentation is about ….

IEC 61850 Global2019
HELINKSWe are going to cover the following topics
• SCL files SCD-ICD-SSD
IEC 61850 Tools and Process
• Why has it nearly not been used?
• Why should it be used?
• How can it be used to improve overall efficiency
System Specification with SSD Files
• Impose IEC 61850 IED data model to supplier.
• Impose formalized, detailed design to supplier.
Different approaches on system specification
• Additional Requirements on IEC61850 Standardization
• Additional Requirements on Tools and Key Players

HELINKSThe useless SSD ….
▪ Why did Utilities not use SSD files for system
specification and tendering?
▪ Why did System Integrators not use SSD files for
designing the system?

HELINKS▪ The content of the Process Section is
by far not sufficient to specify a
Power Automation System.
▪ Organization did not fit.
▪ Challenging task of defining IEC
61850 mapping … for different IED
types
▪ Utility name spaces even more
challenging.
▪ Potential benefit for maintenance and
quality not recognized.

HELINKSMissing Content
▪ Custom Signal designations
▪ HMI texts ( Alarms/Events)
▪ Processing and routing information
▪ Applications & Logic
▪ Physical IO
▪ Protocolmappings e.g. IEC 60570-104 or DNP 3 Addresses
▪ Test information
IEC 61850 Global2019
HELINKS▪ The content of the Process Section does
not really help to build a Power
Automation System.
▪ Why draw again a Single Line if it already
exists?
▪ Where is the productivity gain in mapping
hundreds of logical nodes in SCL.
▪ Customers did not require an SCD with
Substation section.

HELINKSDrawback
System Integrators delivered very different solutions for similar systems.
No transparency of the design
Device interchangeability was hard to achieve.
Utilities lost grip on the installation
Maintenance became difficult and expensive
IEC 61850 Global2019
HELINKSUtilities took action ….
• Representatives joined TC57 WG10 and initiated User Feedback task-force
• Osmose project
ENTSO-E
• Utilities participated more intensively in IEC 61850 working group.
• Utilities left the “Asset Manager” comfort zone.
• Utilities defined IEC 61850 design standards and processes.
• Utilities invested in IEC 61850 training.
Investments in IEC 61850 design standards
IEC 61850 Global2019
HELINKS…and define solutions with different technical approaches:….
Impose Standard IED design to
suppliers (virtual IED)
Develop Utility Standards and
define mapping to different IED data
models
IEC 61850 Global2019
HELINKS…. and different pros and cons:
• Representatives joined TC57 WG10 and initiated User Feedback task-force
• Osmose project
ENTSO-E
• Utilities participated more intensively in IEC 61850 working group.
• Utilities left the “Asset Manager” comfort zone.
• Utilities defined IEC 61850 design standards and processes.
• Utilities invested in IEC 61850 training.
Investments in IEC 61850 design standards
IEC 61850 Global2019
HELINKS…. with different technical approaches:
Impose Standard IED design to suppliers (virtual IED)
+ Simpler to handle for Utilities
- Only large Utilities can “force” design upon manufacturers
- Standards are inflexible and hard to maintain
Develop Utility Standards and define mapping to different IED
data models
- Higher complexity because different IED Data Models need to be mapped.
+ More flexible and works also for smaller Utilities
+ Covers more IEDs on the market.
+ Standards are IED independent. Only the IED mapping needs maintance.
IEC 61850 Global2019
HELINKSVery sad ……
• Proprietary solutions
• Not represented in SCL
• No processing by IEC 61850 Engineering tools
In both approaches the
SSD file as a formal
specification is not really a key element!!!
IEC 61850 Global2019
HELINKSHow to enable Utilities to build more efficiently their systems
• SSD files need to contain enough information to specify most aspects of a power automation system independently of the IED architecture.
• IEC 61850 Standard needs to show the way from IED independent system specification to implementation.
IEC 61850 Standard
• Engineering tools must extend IEC 61850 communication engineering to general signal and application engineering.
• Engineering tools must support company design standards and SCL representation.
• Engineering tools must bridge the gap between customer data model and vendor specific implementations.

HELINKSWhat can SSD be used for
Graphical representation of electrical scheme (Single Line) and the automation functions for
documentation
Base for colouring of HMI (monitoring and control systems)
Automated generation of standardized functional specification
Generation of structured function oriented signal lists with hierarchical naming.
Allocation of control and protection functions of the secondary equipment (IED‘s)
