Advanced Electrical Power Systems
To reduce weight, enhance efficiency and improve reliability and maintainability, many hydraulic, mechanical and pneumatic systems on aircraft are being replaced by electrical equipment. However, the transition to more electric technologies is creating many challenges.
The research themes relating to advanced aerospace electrical power systems that have been identified by AeIGT as necessary to advance the state of competitiveness are:
- Electrical Materials
- Electrical Machines
- Power Electronics
- Thermal Management
- Power Distribution Architectures
- Condition Monitoring
In the School of Electrical and Electronic Engineering, the Power Conversion Group and the Electrical Energy and Power Systems Group are working in many of these areas. Together these two Groups comprise one of the largest single academic research bases in electrical technology in the UK
Power Conversion Group
The efficient conversion & control of electrical energy is a vital infrastructure technology that underpins much of what we take for granted in an industrialised country; electricity generation & distribution, land, sea & air transport, computer & communications systems, & countless industrial processes.The Power Conversion Group is active in many of these areas, undertaking both fundamental & applied research that covers:
- Electrical Machines
- Power Electronic Circuits & Systems
- Motor Drivers & Actuators
- Superconducting Devices
- Fuel Cell & Energy Storage Systems
- Power Electronics Enabled Electrical Systems for Aircraft, Vehicles & Ships
With eight Academic Staff & a team of almost forty Research Staff & Students, the Group is one of the largest in this area, in the UK. The Group has recently benefited from University investment in the form of three new academic posts. In addition to EPSRC, DTI & EU Grants, the Group's funding portfolio includes the Rolls-Royce University Technology Centre in Electrical Systems for Extreme Environments. Approimately 50% of the Group's activities are concerned with aerospace applications
Power Conversion Research at the University of Manchester
University of Manchester research in this area is principally concerned with electro-mechanical & solid-state techniques for the conversion & control of electrical power across a wide range of applications, especially sustainable transport & energy supply, more specifically:
- Power Conversion, Control & Distribution for Aerospace Applications
- Marine Electrical Systems
- Energy Efficiency in Industrial Motors & Drives
- Electric Vehicle Systems
- Renewable Power Generation & Active Management of Distribution Systems
One of the main aerospace related projects that is currently underway within the Group is the Integrated Electrical Power Networks Evaluation Facility (IEPNEF), a 100kW experimental platform for studying the complete electrical systems of uninhabited aerial vehicles (UAVs). The facility is being funded by Rolls-Royce and the Defence technology Centre (DTC) in Systems Engineering for Autonomous Systems (SEAS). Research based in the facility includes engine embedded generation technologies, systems architectures, power quality and stability, system control and energy storage, fault management and protection. The Group is also heavily involved in MOET (More Open Electrical Technologies), the Airbus-led FP6 project that is devising and validating new power system architectures and standards for aircraft electrical systems. Our role is to undertake systems modelling, simulation and the evaluation of advanced architectures, principally using the Saber software.
Electrical Energy and Power Systems Group
The EEPS group is at the forefront of research and teaching in the field of electric power engineering in the United Kingdom and internationally with its 10 permanent academic members of staff and its 30+ researchers. Our people are in constant contact with industry and at the vanguard of the research trends in electric power engineering. Our research covers 3 main axes:
Power System Analysis, Operation & Economics
We seek innovative solutions to problems of power system reliability and security, demand-side participation, distributed generation integration and planning and operation of the electricity grids of the future.
High Voltage & Power System Plant
We investigate breakdown mechanisms in ageing power system plant infrastructure, novel insulation materials and techniques for aerospace and conventional electric utility applications. Through the Rolls-Royce UTC we are investigating partial discharge management for aerospace electrical power distribution. The work includes voltage limitations for cables and connectors, and design constraints for future electrical distribution systems.
We are also proud to be the home of the National Grid High Voltage Research Centre.
Power System Protection, Control & Communications
We develop the new power system protection, control and communication methodologies needed to improve service reliability and effectively take advantage of dispersed sources of generation.
Advanced Electrical Power System Research Facilities at the University of Manchester
Power Conversion Group
A strong emphasis is placed on the practical testing & validation of new techniques & extensive, well maintained facilities are housed at the University of Manchester.
Three recently refurbished laboratories offer a modern & comfortable working environment. These are well equipped with network, impedance & power analysers, oscilloscopes & current probes. The facilities include:
Electrical Energy and Power Systems Group
The EEPS group has some of the best research facilities in the world that include the largest High Voltage (HV) laboratory of any UK University. We also have extensive bespoke and commercial software available for use.
The National Grid High Voltage Research Centre contains the following equipment:
- 2MV impulse generator
- 800kV AC test set
- 600kV DC test set
- 20kVA high current source (configurable to maximum current of 10kA)
- Salt fog and environmental test chambers
- Modern digital measurement equipment
- Material processing and characterisation equipment
We also have equipment for use in the testing of power system protection and power system communications. This includes a real time digital simulator (RTDS) in which devices can be tested in real time.
- The HV research centre is supported by National Grid
An extensive range of software is used to support our research. This software includes:
- Power System Analysis Packages: IPSA (Interactive Power Systems Analysis) and Powerworld are two commercial packages that we use. We also have a number of specific packages developed to perform studies relating to power system optimisation and power system dynamics.
- Output from the CDEGS software showing earth potential plots-CDEGS: This powerful package is used to peform investigations relating to earthing, stray voltages / currents and electromagnetic coupling
- PSCAD: This power system transient simulator can be used in a wide range of studies ranging from insulation coordination to the simulation of power electronic controllers used within modern power systems
- FEA Simulation: Vector Fields 'OPERA' is used to perform both 2D and 3D finite element analysis, typically using an electrostatic based code.
Postgraduate Study in Advanced Electrical Power Systems
Taught Master of Science (MSc)
We currently offer four MSc courses:
- Electrical Energy Conversion Systems
- Electrical Power Engineering
- Power System Engineering & Economics
- Sustainable Electricity Supply
A student is able to graduate with an excellent knowledge of all important issues relating to the power system from analysis to practical equipment design. MSc graduates from the University of Manchester can currently be found the world over, many occupying high positions within companies involved in various forms of power engineering. By completing an MSc course at the University, you will join this worldwide community.
Research Degrees (PhD / EngD)
A PhD/EngD is the target of most of the postgraduate students working in the school who relish the opportunity to undertake a research project with clear intellectual, scientific, industrial or commercial relevance and challenge. If you come to us from industry you might well find it possible to do the kind of postgraduate work which is of particular value to your organisation as well as to your own advanced training. If you already have some experience of research work you may enter for this degree direct. In almost all cases your supervisor will recommend that you attend modules from the taught MSc courses that the school offers. The PhD then requires a minimum period of three years of full time research. The EngD degree is normally a four-year course with the same high standards of research training as the PhD but also incorporating a framework of industrial management.
