PLC – always up-to-date

PowerLink – the versatile solution

PowerLink uses the high-voltage line between trans-

former substations as a communication path for

data, protection signals and voice. This technology,

which has been tried and tested over decades and

adapted to the latest standards, has two main

application areas:

as a communications link between substations■

where a fiber-optic connection does not exist

or would not be economically viable, and

as a backup system for transmitting protection■

signals parallel to an installed fiber-optic link.

A basic distinction is made between analog (aPLC)

and digital (dPLC) systems. Newer digital systems

allow more efficient use of the frequency band,

whereas traditional analog PLC systems offer advan-

tages in cases where transmission conditions areworse (low signal / noise ratio, for example). With

PowerLink, both operating modes are open to you.

You can even combine aPLC and dPLC services in a

single communications network.

PowerLink – developed for thechallenges of the future

PowerLink has numerous outstanding features and

functional units, many of them are patented. The

real hallmark of the system, however, is its openness

and flexibility, which offers you a host of technical

options for the best operation of your communica-

tion networks. You can use PowerLink for the trans-

mission of

Protection signals■

Telecontrol signals■

Voice■

Fax■

Data■

TCP / IP communications■

For this purpose, PowerLink has analog and all cur-

rent digital interfaces. Because these can be com-bined flexibly, you can protect investments you have

already made, and continue to use the older analog

terminals while you gradually switch over to the new

communication technologies. At the same time,

with PowerLink you already have all the possibilities

of TCP / IP communication at your disposal, which is

increasingly emerging as the standard in the power

supply area as well.

A few years ago, it was looking as if digital fiber-optic networks wouldreplace the traditional PLC (power line carrier) systems at power supplyutilities. As it turns out, however, PLC is still an indispensable communi-cations alternative for numerous applications and will remain so in thefuture: This technology ensures extremely high standards of communi-cation in network protection, and can easily be integrated into a widerange of communication networks, as in the case of the SiemensPowerLink PLC system.

Perfect matching to modern communication environments, and built-intechnical potential for the requirements of the future, make PLC systemsmore attractive today than ever before.

PowerLink –highlights in the package

Flexibility for your success

Versatility is one of the great strengths of the PowerLink system.

PowerLink can be matched flexibly to your infrastructure.

Variable transmission power

You can, for example, set the system power via the system software in two

ranges (20 to 50 W or 40 to 100 W) according to the exact requirements

of the transmission route. As far as the transmission itself is concerned,

PowerLink operates with variable data rates and bandwidths in the frequency

band between 24 and 1000 kHz, making it easy to comply with specific

frequency requirements of customers.

Optimum matching to transmission conditions

PowerLink matches the data rate to changes in ambient conditions. This

guarantees optimum transmission power in the network at all times. Due

to PowerLink’s integral prioritization function, which can be configured for

each channel, routing of the most important channels is assured even in

bad weather conditions.

Multi-service devicePowerLink offers the necessary flexibility for transmitting every service the

customer might want in the available band. All services can be combined

in any way within the available bandwidth / bit rate framework.

As a power system operator, your emphasis is onsystem performance. Thanks to a comprehensiveservice portfolio, PowerLink can help you optimizecommunications in your system, utilize band-width efficiently, and permanently improve thereliability of your network operations. The mostimportant aspect of PowerLink is flexibility,always offering you the best possible transmission

performance under all operating conditions.

Automatic crosstalk canceller (AXC)

PowerLink can be operated with or without space

between the transmission and reception bands.

Band to band operation usually requires manual

adjustment to minimize the influence of the trans-

mitter on the receiver. AXC automates this adjust-

ment process, thereby optimizing the transmission

quality. Developed and patented by Siemens, AXC

automatically subtracts the interfering transmission

signals from reception signals (RX-TX). With chang-

ing characteristics of the transmission channel, the

quick adaptation of the AXC ensures optimum trans-

mission quality at all times, without time-consuming

manual adjustment.

Transmission capacity up to 256 kbit / s

PowerLink offers a transmission capacity of

256 kbit / s, and an integrated TCP / IP interface is

available. This means that many different types of

IP terminals can use the power line communications

network effectively.

Maximum efficiency: the integrated,versatile multiplexer (vMUX)

A large number of conventional communication interfaces today

(e.g. a / b telephone, V.24, X.21, etc.) and in the foreseeable

future must be operated in a switching station. For this purpose,

PowerLink uses an integrated versatile multiplexer that bundles

these communication forms together and transmits them by

PLC. The vMUX is a statistical multiplexer with priority control.

Asynchronous data channels can be transmitted in “guaranteed”

or “best effort” modes, to guarantee optimum utilization of

available transmission capacity. The priority control ensures

reliable transmission of the most important asynchronous and

synchronous data channels and voice channels even under poor

transmission conditions. Naturally the vMUX is integrated in the

management system of PowerLink, and is perfectly equipped

for the power line communication requirements of the future

with extended options for transmitting digital voice and data

signals.


7/207

Voice compression – less is more

Voice compression is indispensable for the efficient utilization

of networks. Naturally, quality must not suffer, which is why

PowerLink offers comprehensive options for adapting the data

rate to individual requirements. PowerLink offers different com-

pression stages between 5.3 and 8 kbit / s. To prevent any im-

pairment of voice quality, the compressed voice band is routed

transparently to PowerLink stations connected in line, without

any further compression or decompression.

Protection signal transmission systemSWT 3000

A maximum of two independent SWT 3000 systems can be

integrated into each PowerLink. This means that no connection

components are needed. SWT 3000 systems are also fully inte-

grated into the user interface of the PowerLink administration

tool.

One management systemfor all applications

PowerLink not only simplifies your communications, but also

makes communications cost-efficient. The PowerSys software

administers all integrated applications of PowerLink under a stan-

dard user interface. This ensures higher operating security while

cutting training times and costs to the minimum.

PowerLink for data transmission

LAN connection

PowerLink permits establishing a LAN connection

between substations in the high-voltage network.

As well as connecting routers via the X.21 interface,

PowerLink also provides an integrated Ethernet inter-

face. This allows IP-enabled data terminal equipment

to be connected directly at low cost.

Transparent analog data transfer

When PowerLink is used in analog mode, a maximum

of four conventional asynchronous data channels up

to 2400 bit / s can be transmitted transparently bymeans of FSK modulation.

The versatile multiplexer integrated in PowerLink

provides the following functions:

Asynchronous data transmission

Up to eight data terminal equipments can be con-

nected to the PowerLink via the RS232 interface.

These asynchronous data channels can be transmit-

ted in the “guaranteed” or “best effort” modes, and

thus guarantee optimum utilization of the available

transmission capacity.

Synchronous data transmissionPowerLink provides 2 X.21 or 1 G703.1 interfaces

for the data link between plesiochronous (PDH) or

synchronous (SDH) transmission networks.

PowerLink for telephone networks

If you want to set up a telephone network using

PLC units, PowerLink is the reliable way to do this by

simply using your existing TC systems and telephones.

PowerLink is designed for the connection of all

different kinds of telephone systems or for individual

telephones (from analog to IP).

The graphics above provide an overview.

The compressed voice band is routed transparently

with no additional compression or decompression,

so that the voice quality at PowerLink stations con-

nected in between is not impaired. This StationLink

functionality for voice channels is shown in the

following graphic.

The protection signal transmission system SWT 3000can be operated as an integrated system (max. 2

systems) or adapted with PowerLink. Every

SWT 3000 system can transmit up to four protection

commands. Above graphic shows an overview of the

various connection options.

The SWT 3000 system offers you a unique

and varied range of operating options:

Single-purpose mode:■

In this operating mode, the PowerLink transmis-

sion channel is used exclusively for transmitting

protection signals. Maximum transmission ranges

with greatest reliability in the case of pulse noiseand the minimum signal propagation delay are

attained in this mode. A 2-kHz-variant allows the

best possible utilization of frequency space in the

4-kHz band.

PowerLink for protection signal transmission

Multi-purpose mode:■

In this mode voice and data are transmitted

parallel to protection signals.

Alternate multi-purpose mode:■

In this mode, the entire transmission capacity is

used for voice and data as long as it is not needed

for protection purposes. The PowerLink pilot tone

is used as the guard tone in this mode. If a protec-

tion command needs to be transmitted, voice

transmission is interrupted for the duration of

transmission of the protection command. Data

transmission may also be interrupted if the rele-

vant parameter is set.

Easy to operate –the PowerLink management system

When analyzing the costs of an infrastructure investment, the expenseof training employees cannot be disregarded. The gratifyingly lowcosts for training in PowerLink are due to the easy-to-learn, intuitiveuser interface, standard for all system components. All applications inPowerLink, such as the versatile multiplexer and the integrated andexternal SWT 3000 devices, use a standard user interface. Your employeeseverywhere can familiarize themselves quickly, so training times andcosts are minimized.

PowerSys administration interface

Intuitive and easy to operate, the Windows-based

PowerSys system software runs on all standard PCs.

Apart from local operation, PowerLink also offers

three options for remote administration. This makes

it possible to meet a wide range of different infra-

structure requirements of customers. Regardless of

the chosen solution, the user has complete system

functionality in the same way as with a direct local

connection.
