Abstract of the Presentation
Title: Substation Automation System –
An Introduction to IEC 61850
ABSTRACT:
The presentation is about substation automation system (SAS) based on the IEC
Standard 61850. It discusses the history of substation automation; explains the
need for the technology, the problem the industry continue to face and solution
proposed by SAS. The presentation provides an introductory discussion of the

1. What is Substation Automation
Substation Automation is the process of monitoring, controlling, protection
and securing operations of primary substation equipment, with the use of
computing and communication technologies.
IEC 61850 is a standard for the design of electrical substation automation.
•is part of the International Electro-technical Commission's (IEC) Technical
Committee 57 (TC57) reference architecture for electric power systems.
•for its main substation engineering philosophy, uses, :
•abstract data modeling,
•substation configuration language,
•fast communication system using generic object-oriented substation
event (GOOSE) signals and
•ethernet technologies using fiber optics and high speed copper
cabling infrastructure.
•Its main goal is interoperability of equipment among vendors, and
•Long term stability of the standard, i.e. making it future-proof

Photos of primary equipment

Main system elements in a substation control
system are:
•IED’s (Intelligent Electronic Devices)
•Bay controller
•HMI – Human Machine Interface
•Communications bus or busses, linking various
devices
•Communication Link to the remote SCADA system or
Network Control Center
•We call the equipment above, the secondary
equipment.

Functions of Secondary System
1. Protection
2. Control
3. Metering for operation & settlement
4. Monitoring
5. Analysis and diagnostics
6. Support for intelligence for operation and
restoration
7. Automatic documentation
8. Safe and secure operation

The power grid is so complex, Substation Automation is critical to its
management.
We need to know more about what is going on in the Substation, which is
focus of our data gathering and controlling and management in general.
The interlocking of switches and control sequence requirements are easily
solved by mathematical logic which is best suited to application of
computers and communication

Communication System Needs
Communication is critically required in Power System real time operation
Telephone system was used as early as 1930’s for dispatch and switching
and comm with Control Centers, and status/control of few points
In 1960s, digital comm became available, but still operating on low BW.
Cost of the optimization was the time it took to complete process

As we move into the digital age:
• literally, thousands of analog and digital points are available
in a single IED
• Communication bandwith no longer limiting factor
• Substation to master comm data paths operating at 64 Kbps became
commonplace with obvious migration path to higher rates;
•With this migration in technology, the cost component of a data
acquisition system has now become the configuration and
documentation component
•Also a key component of a comm system is the ability to describe
themselves from both a data and services
