Methods for measurement of space charge in dielectric solids are well advanced and have been widely reported. This project will consider the optical measurement method of Kerr effect for quantifying space charge in a dielectric fluid. Although the experiments are relatively straightforward careful consideration needs to be given to analysis of obtained image data as any dielectrophoretic effects will need to be accounted for. Ultimately the aim of the project is to develop a tool that will facilitate the study of dielectric fluid behaviour in electric fields at a macroscale.

This project is focused on developing epoxy nano/micro composites which can be used in electrical insulation systems. The objectives include: 1) optimising functionalised and reactive nanofillers to meet specified applications in insulating components. 2) manufacturing & testing a number of large components (industry scale) to verify their performance, 3) exploitation and dissemination, including value-chain analysis and the development of strategic partnering and licensing strategies to facilitate broader use of the IP produced in the project.
It aims to reduce cost and CO2 emission, and improve system reliability/availability.

A distributed optimization-based secondary control framework is aimed to be developed to optimally utilize the distributed energy resources in an islanded microgrid to enhance the stability of the network. The control system is motivated to handle the interactions among the distributed energy resources, as they maintain the voltage and frequency of the microgrid within the specification, keep the power balanced and shared among them, and at the same time improve the power quality of the network.

High voltage direct current (HVDC) power transmission has received significant attraction recently due to the interests in off-shore wind farms and supergrid. HVDC transformers are an integral part of the HVDC transmission system and are one of the most expensive components. The insulation system in the HVDC transformers experiences both AC and DC voltages and its characteristics under such conditions need to be fully understood to ensure its reliable operation. One of the major issues related to HVDC transformers is the electric field distribution due to easy formation of space charge under dc voltage. The present project intends to address the electric field distribution and its relationship with temperature and polarity reversal using numeric modelling. Space charge data for oil/paper insulation will be experimentally obtained using the pulsed electroacoustic technique and they will be incorporated into the model. The outcomes of the project will benefit both electricity operator and transformer manufacturers in terms of reliability and polarity reversal tests.

Space charge accumulation in polymeric insulation could distort the field distribution and affect the insulation properties. In this project, charge injection and transportation inside the polymeric insulation will be investigated by numerical modelling and experimental measurements. The thermal impacts on space charge behaviours will be especially considered. A modified numerical model is expected to be built which can be used to study the charge dynamics and to anticipate the electric field variation across the insulation. In order to obtain the space charge dynamics under practical application situations, a cable PEA system is built which considering the thermal effects caused by the current flowing in the core of cable.

The proposed work will focus on the HVDC cable related properties of PP-based nanocomposites. The characteristic of the nanodielectrics interphase will be the main research object because the interphase can be the dominant factor of nanodielectrics. The proposed work will dedicate to following issues:
ââ¬Â¢ To formulate and characterise the interphase region between nano-fillers and the matrix in surface chemistry aspect. ââ¬Â¢ To investigate how the surface state of nano-fillers affect the polymer-filler interphase. ââ¬Â¢ To investigate the role of the interphase in determining the properties of nanodielectrics

This project has been investigated thermal ageing effects on the changes in physicochemical and electrical properties of polyethylene widely using in the high voltage cable. The project, in particular, contributes to more understanding the changes in charge transport dynamics associated with the different ageing formation and concentration depending on the ageing procedure, temperature and controlled morphology of the polyethylene (HDPE and LDPE blended polyethylene).

The aim of this project is to develop a multiphysics model of a HTGR gas turbine power station. Particular attention will be paid in selection of Printed Circuit Heat Exchanger (PCHE) design as well as working fluid. The study will investigate performance of various geometry of heat exchanger aligned with working fluid. Different shape of channels as well as various working fluids become interesting challenges to be analysed. Thermal energy optimisation from selected PCHE and working fluid and Closed Brayton Cycle matching is another challenge. The final goal of this research is a multiphysics model for HTGR gas turbine power plant with the best PCHE and working fluid performance.
