HELINKSThis Presentation is about ….

How Utilities can

efficiently build and

maintain IEC 61850

Power Automation-

Systems !!!


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.

▪ 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


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


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


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


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


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.


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!!!


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)
