I accept the conditions.
This project seeks to improve upon and overcome the limitations of the phase 1 design to allow for better access, physical range, positional control and visual imaging capability, whilst accepting any improvements that can also be made to spectroscopic measurements. The scope of the project is to have a fully refined, assembled and functional intrascope probe system which has been both mechanically and functionally proven within a laboratory-based environment and via field trials.This will be achieved by making the following developments to the Intrascope toolkit;
online trial of PD monitoring systems incorporating alternative technologies and
suppliers at selected sites and integrate with SHE Transmissions SCADA system
in order to collect, store and analyse output PD event data to establish if
this can be used to improve the management of safety critical plant. Learning
from this project will also be used for further work to incorporate PD failure
precursors into control and protection schemes.
Remote Asset INertial Monitoring and Alerting Network (RAINMAN) innovation
project, once complete, will allow monitoring via a web-based server making it
possible to pin-point the location of any unusual disturbances on the
electricity network. This could mean quicker fault restoration following
weather events, and even the detection of problems before they occur.
project seeks to develop a prototype to evaluate the condition of the core of
ACCC conductors. It will aim to gain an understanding of the effectiveness of
the ACCC composite core inspection tool in evaluating the carbon core.
The aim of
this project was the development of a passive fault level monirtoing programme
across six transmission substations providing good coverage of fault levels
across the SHE Transmission system in the North of Scotland.
Line Inspections by Semi-Autonomous
Systems (LISAS) this project will be the first time a highly autonomus robot
will be used to inpsect the electricity networks in the United Kingdom. LISAS
will trial a robot system capable of making its own decisions whithout human
control. It will navigate its own route as it moves form overhead line to
overhead line, seamlessly navigating from steel tower to steel tower, as it
capties critical asset data to inform reinforcement and maintenance
The lack of a clear and consistent commercial approach to quantify and analyse the social and environmental impacts of network developments alongside the economic costs and benefits and illustrate their quantification in a transparent way has let to overreliance on subjective interpretation by TOs and external bodies including planning authorities and potential objectors. This, in turn, has lead to significant delays in projects while these impacts are debated, resulting in an increased cost to deliver infrastructure projects, borne by network customers.An example of this would be the Beauly Denny line which was delayed for 3 years while a Public Enquiry was held of the potential impacts of the transmission line on the Scottish Highlands. An estimated cost of £81m was agreed with Ofgem to mitigate the 73 planning consent conditions identified in during the public enquiry; a cost to electricity consumers which could potentially be reduced in future projects from a refined assessment of the social and environmental impacts.Key activities
Key features• Develop a small scale system for predicting the remaining useful life (RUL) of an electromagnetic relay.• Identify optimal tools for determining asset health and forecasting RUL.• Develop an online oil condition monitoring and prognostics system prototype incorporating a dedicated intelligent sensor system.• Demonstrate the prototype on decommissioned transformers in SHE Transmission’s licence area.
• Determine the method’s viability to reduce construction time and associated costs.• Understand the extent to which the method can reduce the need for temporary access roads and the level of potential environmental benefit from this.• Establish a best practice, procedure or methodology for using the method in the construction of transmission towers• Investigate the range of tower designs to which the method would be applicable.
This project will install a CAT-1 Transmission
Line Monitoring system on a SHE Transmission line and demonstrate whether it
can enable dynamic line rating resulting in safe and cost-effective line
operation close to its thermal rating.
This has the potential to achieve additional
transmission line capacity without the need for physical line uprating,
resulting in Capex and Opex savings.
The project will verify the correlation between
practical observations and the theoretical model already established, and
determine system planning required in case of wider adoption of the method.
This project will develop a new method that
will allow reproducible results for the distribution of nano scale fillers into
polymeric insulation material. Scalability of the techniques will be
demonstrated through the creation and testing of prototype full size bushings.
To do this a new manufacturing method will be developed.
This new material may have potential to allow
the reduction in size of insulators in HVDC systems by demonstrating enhanced
The overall objective of the project is to develop
a design for a DC/DC converter which could subsequently (as part of a potential
separate project) be developed further into a laboratory demonstration.
The design of a DC/DC converter will be optimised
and integration with HVDC systems investigated.
intention of this project is to leverage innovations (for example: ICAs and
low-sag conductors) to design a new suite of transmission structures to exploit
fully their potential.
scope of the project will include the following:
project will build and verify simulation models of lightning strikes on lines
where the towers have high footing resistances (applicable to steel-lattice
towers at voltages of 132kV and above), and investigate the protection options
to inform decisions on lightning protection approaches.
This project will conduct a study aimed at establishing the feasibility of installing a trial MCSR on the SHE Transmission network including considerations of location, performance specification, and relevant system data. Risk analysis of the technology and training, operation and maintenance requirements will be reported.The outputs will provide a basis for deciding the viability of installing a trial MCSR on SHE Transmission’s operational network without compromising safety, health and the environment as enshrined in GB statutes.
Key Activities• Establish the best location for installing a trial MCSR, its performance specification and the relevant system data for the chosen location• Complete a detailed design of MCSR with capability to be adapted for the functionality of an SVC and including all associated electrical and civil designs• Perform risk analysis of the technology
The current approach to substation
construction differs little from that of 60 years ago; meanwhile many
innovations in design and civil engineering could create a substation which is
cheaper, faster to deploy and more suited to GB’s low carbon energy future
This project defined the
requirements for a modular approach to transmission substation from design to
An assessment of the alternative
approaches to traditional substation design and construction techniques has
created recommendations for Transmission Operators to employ new approaches, including
potential changes to design and operational standards.
The success of this project has resulted in an
additional project to fully design, construct, install and monitor an
alternative substation based on the design work completed in this project.
SHE Transmission proposes to demonstrate and deploy a permanent substation designed using a Modular Approach to Substation Construction (MASC) based on the design development work completed as part of NIA SHET 0013.
