What does influence effective communication?
Language
Dialect
Different Language
Slang
Translation
Accent
The communication is process whereby information is transferred from a sender to receiver.
The receiver could be an individual person, a group of persons or even an audience.
What does influence effective communication? First of all it is language.
Different language
There are a lot of nations around the globe speaking completely different languages about the same topics .
Dialects
Individual regions in each country could have common language but different dialects .
Slang
Moreover in some towns and cities slang is used not to be all so easy.
Translation
Even thought some of us can speak in different languages, we can make fault interpretation in our head.
The simplest way of successful communication is to used the same language without dialects, slang!!!

What does influence effective communication?
Way of transmitting
Bottlenecks
Homogenous environment
What else can affect communication?
The same language is just one condition of effective communication, the second one is way of transmitting.
Just imagine wall among us! Our speech will be muted and the person behind the wall can hear only fragments of our speech.
To avoid loosing some information the homogenous environment should be used.
Bottleneck? Of course, data can be delayed due to it.
And there are other examples.

Let‘s talk about communication in substation, there is jungle of languages and different ways of transmission.
There are a lot of different languages used to communicate between devices on different level.
Some of them are typical for industry, utility etc. Some of them are open to other vendor, some of them are vendor specific.
Moreover there is no or minimum languages among devices on the same level.
If devices speak in different languages, interpreter has to be used, but it brings in majority cases losing of some information, more engineering, faults
There are a lot of way of transmitting linked with language. Both used language and way of transmitting influence reliability of system, system response,
engineering, amount of data.
Amount of data

More simlified life = IEC standard
One World One Technology One Standard
IEC standard
One global language for all
Widespread, Extra fast, Reliable Way of transmission
Communications networks and systems for power utility automation
To make your life more simplified, choose IEC standard and exploit its benefits.
The standard offers on the one hand one global language for all without exception, it is applicable to both ANSI and IEC world
and has been developed in co-operatrion between vendors (ABB, Schneider, Siemens, GE, Toshiba, ...) together with major utilities (Vattenfall, RWE, EDF, Iberdrola, ENEL, ...)
On the other hand it offers widespread, extra fast and reliable way of transmission – Ethernet.
In technical words IEC standard represents Architecture for power utility automation, if you want, it is Esperanto for Communication in substation.

6. IEC 61850 enabled MV Primary Switchgear
IEC Standard / The Main ideas
Same language
The same language for all, dialects are not allowed
Descriptive, unique words
Standardized Configuration language
Devices and systems from different vendor (ABB, …) talk to each other in the same language without dialects, slangs, … so anybody understands.
It is easy to integrate devices from different vendors into projects.
Words are self descriptive, there is no need of additional explanation. The meaning of words is unique, not possible misunderstanding.
Standardized Configuration languages is used for efficient engineering and information exchange e.g. between devices and system configuration tools
from different vendors.

7. IEC 61850 enabled MV Primary Switchgear
IEC Standard / The Main ideas
Free configuration
Free allocation of functionalities
Different application philosophies
Centralized and / or decentralized solutions
IEC standard allows free allocation of functionalities to devices on all levels . This allows to create different application philosophies
(more centralized and/or decentralized solutions). Free configuration supports tailored design of Substation Automation System architecture
to meet specific needs and operation.

8. IEC 61850 enabled MV Primary Switchgear
IEC Standard / The Main ideas
Long term stability
Communication = Language (IEC 61850) + Way of transmitting (Ethernet)
Language and Way are spllited
Gives the benefit of the evolving communication technologies advantages
The third key idea of the standard is independency of language from advancing way of transmission. Language is represented by IEC 61850
and Ethernet , which has been with us for many years and is the basis for vast majority of office networks around the world , was selected as way of transmitting.
The separation of two essential parts of communication gives us the benefits of the evolving communication technologies.
Analogy:
First half 19. Century - optical semaphore telegraph system followed by Electrical telegraph – electrical pulses
Second half 19. Century - Telephone – Transmit and receive sound over wire lines
Second half of 20 century – Mobile phone – transmit and receive sound without wires.

Used network (Ethernet) enables easy extension of substation and easy integration by utilizing the same networking technology
that is being used across utility or industrial enterprise. (Shorter Down time)
Save time
Time for configuration and commission devices is reduced, because IEC devices don’t required as much manual configuration as legacy devices.
Client applications retrieve signal list directly from device or import it via standardized configuration file. Most manual configuration is eliminated
thereby errors are drastically reduced. (Faster commissioning)
Connectivity
Quick and easy connection to the upper level system by the help of file import with standardized configuration language.
e.g. RTUs, MicroSCADA, 800xA and easy engineering (Easy access to needed data)
Improved diagnostic
The communication link between IEDs is constantly supervised, link status is known before use, it isn’t valid for conventional wiring
(faster and earlier elimination of errors)
Performance
High bandwidth providing higher level of functionality (e.g. priority for GOOSE and Sampled Measured Values) , shorter response time
E.g. Distributed ARC protection is faster and more safe – in general
Asset management
More information about devices in primary and secondary technology are available where data is named using descriptive string to describe the data
defined by IEC standard and provided in power system context that enables to immediately identify the meaning of data.

IEC Standard / Station bus
1st device, will you send me information about ..?
It’s Horizontal
GOOSE communication
It’s vertical communication
I can hear you and help you
I have problem to perform operation
Yes, I will
IEC standard specifies Station communication. It distinguish vertical and horizontal one.
Vertical communication is non-time critical communication mainly among Intelligent Electronic Devices and Substation Automation systems.
Horizontal GOOSE communication is real time and time critical communication between Intelligent Electronic Devices.
It has priority to vertical communication. It is used to transmit e.g. interlocking, blocking , … signals between panels in substation.

15. IEC 61850 enabled MV Primary Switchgear
Usage
Fast horizontal GOOSE communication between panels / IEDs
True IEC support with Relion® IEDs

16. IEC 61850 enabled MV Primary Switchgear
Conventional vs. GOOSE approach
Conventional approach
Wiring between devices must be done individually per signal …
Horizontal GOOSE communication
Number of interconnections is equal to number of devices
Communication Network (Ethernet)
Conventional approach
Wiring between the IEDs has to be done individually for each signal, from bay device to bay device. An output signal can be shared,
but inputs have to be used individually.
GOOSE
Where Horizontal GOOSE communication is implemented, Low Voltage Compartment production is independent of the logic, automatic , …
between panels (interlocking, blocking etc.). All Intelligent Electronic Devices (IEDs) are connected via a single connection to the network
and the Data is shared across all IEDs.
This approach means less wires, less terminals, less testing, less errors, … comparing previous mentioned approach. …

17. IEC 61850 enabled MV Primary Switchgear
GOOSE approach Benefits
Faster performance
Horizontal GOOSE communication is faster than hardwired one
Higher error detection
Interruption of communication link is detected within configurable setting
Preconfigured fail-safe operation in case of failure
Tested and proved by KEMA
Performance tests according to IEC
All IEC61850 components used in MV Primary switchgear are certified by KEMA: Intelligent electronic Devices, Ethernet switches, Switchgear – Inspection report
Comparison of the hardwired and GOOSE performance of UniGear and ZX switchgear panels with Relion® Protection and Control IEDs
based on IEC performed by KEMA proved that:
GOOSE performance is faster than the overall hardwired performance
GOOSE reliability and interruption of the Ethernet link are detected within a configurable setting
Performance
Faster signal transfer , time saving has real meaning in terms of substation
Improved diagnostic
The safety of the system is enhanced by mean of constantly supervised connection,
Lost wire contact isn’t immediately noticed, but with IEC it is and IED can perform preconfigured fail-save action.

18. IEC 61850 enabled MV Primary Switchgear
GOOSE approach Benefits
Interconnections between panels (conventional vs. GOOSE approach)
Simplicity
All devices are connected via single attachment to the network
Higher level of standardization
Standardized mechanical and electrical connections and links
Logics can be defined after construction phase
Less I/O HW in IEDs
The IEC standard affects not only the design of Intelligent Electronic Devices , monitoring and control systems,
but also the design of the substation secondary circuit.
Horizontal GOOSE communication between IEDs in a substation using the substation's local area network will bring
new added value to customers in all aspects compared to the traditional method of signal transfer.
First of all it is simplicity, all IEDs are connected via single attachment to network.
The standardization of the panels will shorten the workflow process in factory since the logics can be defined after
the construction phase and fewer documents are needed before starting the construction phase.
It will be easier to build a standardized panel since the logic is on the network
and the number of cables to be wired is minimized.
