PhD Studentship: Integrated Gas-turbine Driven Generation

University of Nottingham - Engineering

Location: University Park

Applications are sought for a PhD-level study at the University of Nottingham in integrated gas-turbine driven power generation. The successful candidate will have a first-class (or upper second-class) honours degree in either electrical or mechanical engineering and will be required to demonstrate at least some knowledge of the other field and willingness to expand knowledge in that area.

Because this is an “Industrial CASE” studentship, the position is open to UK nationals only and it will attract a stipend of at least £17K per annum for three years. The position arises from a collaboration between the University of Nottingham and SIEMENS – a world-leading manufacturer of gas turbines for power generation with a manufacturing base in Lincoln.

Traditionally, gas-turbine powered generators utilise a gearbox to reduce the speed of the gas turbine drive shaft down to a speed where a synchronous generator can produce the required 50Hz (60Hz in the USA) frequency of the electricity grid. Fundamentally, this study will explore the viability of a set of new configurations of gas turbine generator sets where the power shaft of the gas turbine is coupled directly to a generator so that they spin at the same speed. The gearbox is then removed. Because the generator will then be spinning at a speed much higher than synchronous speed, it is necessary to use a set of power-electronics to convert the power from the generator to synchronous frequency. This PhD will address the complete set of considerations involved in making an engineering judgement for what arrangements of integrated gas-turbine generation will be commercially viable in the near future – and what will subsequently be possible in the future.

The PhD will be hosted in the Faculty of Engineering at Nottingham and the successful candidate will spend some time in the Gas Turbine Transmission Systems Research Centre and some with the Power Electronics, Machines and Drives research group. He/she will also have the opportunity to spend some short periods at SIEMENs itself in Lincoln.

Applications are requested by August 21, 2017. Any clarifications can be sought from Seamus.Garvey@nottingham.ac.uk but applications will be accepted via the formal system only. Interviews are likely to be held on Sept 6, 2017 and the successful candidate will receive confirmation very shortly afterwards.
