Project: VISOR
Visualisation of Real Time System Dynamics using Wide Area Monitoring
Aim: Reduce costs to UK consumers through
increased system efficiency and lower network
investment.
Cost: £7.44m Timeframe: Dec 2013 – Mar 2017
Savings: £50m per 100MW investment and £4m per
annum operational savings.
Background:
International consensus is the Transmission network
is changing and a new generation of monitoring and
controlling is required - SPEN intends to bring this
field forward.
Solution:
New monitoring will include time-stamped
synchronised measurements with greater visibility of
dynamic behaviour and sub-synchronous oscillations,
with easy data recall and analysis capability.

VISOR –
“We will develop a system which is capable of monitoring and
modelling the behaviour of the transmission system at a level of
detail and sophistication never achieved before. The outputs will
be used to better inform transmission investment decisions and
to reduce network constraints”

Transient stability closely related
to angle difference
Define limits by Angle, not MW
alone
Possible future use of angle in
new HVDC control

Key Challenges
Complex Project Delivery Organisation
 By its very nature, the project delivery responsibility is split between
multiple businesses and parties. While this adds considerable complexity
to the management and operational aspects of the project, it provides an
excellent opportunity for strong collaboration between the key industry
players.
Procurement Risk
 Software and hardware critical to the core elements of the project.
Procurement of services from Alstom-Psymetrix has successfully avoided
one of the largest risks to VISOR’s completion.
Technically Advanced Objectives
 Project is not simple from a technical perspective. Extra recruitment and
collaboration has brought sufficient expertise to the project to achieve our
targets.
