OPERATIONS
Improved performance
mean increased
income: the same is
true in reverse.
“Combined, transmission and
distribution networks represent a
significant technical legacy,
mirrored in its investment
requirements: current estimates
are US $ 13 trillion worldwide
through to 2030.”

the Electric Power Sector, August 2008]
How can performance be improved?
10

Version 1.3.0
Performance improvement means:
Increasing income through decreasing the quantity and
duration of faults / outages:
“OECD estimates the world
will need more than $1.8
trillion per year over the
next two decades to
upgrade infrastructure. Grid
modernisation is a major
component.”
[The Electricity Economy: New
Opportunities from the
Transformation of the Electric
Power Sector, August 2008]
• Real time / on demand status monitoring
• Early identification and isolation of faults
• Quickly remedying faults when they occur
• Rapid response to attack
And reducing the maintenance cost of the network:
• Carrying out preventative maintenance
• Reduce need for unscheduled site visits
• New infrastructure deployments targeted for best ROI
Improved visibility and control is how this is achieved.

+ Control
Two way real time /

+ Monitoring
“Customer as telemetry”: little
or no asset visibility and
manual fault rectification
No monitoring
However, improving monitoring and control requires improved communications and data.

An aside on IP… where the world is moving
Next generation RTUs / IEDs are IP based:
• Widely accepted, proven, standard
• Network compatibility, interoperability
• Reliable, scalable
• Multiple applications share network resources
• Use over virtually any physical medium
“The speed of technology
change in the
telecommunications market
is high compared with utility
technology. Utilities expect
asset life of up to 40 years.
This exposes utilities to risk
of obsolescence and
associated cost of
maintaining obsolete
technologies..”
[EON, EUTC 2009]
For utilities and SCADA, IP means:
• Network interoperability between devices
• Over-the-air control of remote devices, e.g. SNMP
• Reduced infrastructure and maintenance
• Reduced requirement to visit remote sites
IP also means an open network, which contributes to security concerns for the
communications infrastructure.

Communications are key to enable this change
“The most funded smart grid
startup companies are those
competing in the
communications space”.

Choosing the right communications technologies
Considerations and the role of point-to-multipoint microwave radio
15

Version 1.3.0
Considerations for the communications infrastructure
Security and ownership:
• IP and increased levels of control open
networks to new vulnerabilities and threats
Opex-based options:
GPRS / LTE
Leased lines
Satellite
Financial implications:
• Whole life cost / total cost of ownership
• Reduction of maintenance time and cost
through increased reliability and efficiency
Future proof:
• Last over life of the network while
protecting huge legacy investment in RTUs
• Use infrastructure for other applications
16

Version 1.3.0
Capex-based options:
Fibre / cable
Private mobile radio
WiMAX networks
Spread spectrum unlicensed radio
Power line carrier
Licensed point-to-multipoint radio
Evaluating opex-based options
• GPRS / LTE: cheap, good for basic
monitoring, but can be unreliable, is not
secure, and is controlled by commercial
entity whose core business is servicing other
applications
• Leased lines: can be a good solution where
infrastructure exists, but can be expensive to
deploy and out of the utility’s control,
especially for repair, with high opex costs.
MPLS networks may cause problems for
utilities
• Satellite: reaches remote locations but huge
opex costs, suitable only when no other
solution is available
17

Version 1.3.0
Evaluating capex-based options
• Fibre / cable: highly reliable and secure where available,
but is overkill in distribution networks
• WiMAX / mesh networks: high density applications, but
overkill in most of the distribution network, and spectrum is
expensive
• Private mobile radio: useful where infrastructure exists, not
originally designed for data transmission, new infrastructure
is expensive
• Spread spectrum unlicensed radio: cheap, can be used for
basic monitoring, but always subject to interference, not
suitable for control
• Power line carrier: can be used for some low level
monitoring applications, not suited for most monitoring and
control applications because faults can affect the
communications

Why use point-to-multipoint radio for monitoring and control?
With such a large variety of communications
options available for SCADA, when is point-tomultipoint radio the appropriate choice?
When:
• Monitoring and control must be on
demand or in real time
• Eliminating dependence on a third party to
provide and maintain communications is a
requirement
• Ensuring network security is essential
• Flexibility of communications infrastructure
is essential
• Reducing opex and minimising whole life
cost are key business drivers

Security is no longer physical, nor
“security by obscurity”.
Open networks enable enhanced
monitoring and control, but bring
new vulnerabilities and
opportunities for attack.
It is no longer just ex-employees,
but also those who “hack for fun”
as well as terrorists and state
actors responsible for malicious
attacks.

Standards-based, backwards compatible, future-proof
Investment in equipment needs to support the total
life cost needed when forming budgets.
The Aprisa SR is both backwards compatible and
future-proof:
• Supporting both legacy Serial RTUs and newer
Ethernet enabled IEDs, protecting the legacy
investment through transition over time to IPbased devices
• Integrates seamlessly into existing network
topologies, and is highly configurable to allow
the network to evolve along with increasing
monitoring and control requirements
• Standards-based and supporting all relevant
protocols, for long-term incorporation into
SCADA networks
Plan for the future, protect the past. The best of both
worlds.

Applicable throughout distribution network communications
As more information becomes available to a
utility, having a unified communications
infrastructure makes financial and operational
The Aprisa SR has an integral mini-PCI port,
which can be used to interface with many other
communications technologies, such as WiFi,
GPRS, PLC, Zigbee, ModBus, etc.
This means that it can be used for applications
such as:
• Concentrating and backhauling meter
information to a network operations centre
• Communications for substation security
• Connecting multiple RTUs, wireless or
wired, to a single Aprisa SR unit

Network efficiency and configurability
More efficient communications means more efficient,
on-demand / real time monitoring and control,
informing operational decisions.
An Aprisa SR network is highly configurable and
enables set up to be optimised to match the specific
infrastructure:
• Each unit is configurable as a base station,
repeater or remote unit
• Configure as Layer 2 or Layer 3 network
depending on network size, complexity and
traffic requirements
• Optimise for any given network topology by
configuring in-depth radio parameters such as
back off time and number of retries

Capex investment, opex minimised
Capex investment means a return on investment
over the total life cost can be achieved, although
equipment longevity remains essential.
The Aprisa SR:
• Can be incorporated into a total life cost
business model, because of its future-proof
design and architecture
• While providing superior performance and
security
