Power engineering postgraduate personal statement example

Personal statement example

My interest in power systems grew out of a fairly ordinary problem. My uncle fits domestic solar panels and battery storage, and I have spent most weekends of the last three years helping him with surveys, cable routing, paperwork and the occasional awkward loft. I am not a qualified installer, so my jobs are the unglamorous ones, but they gave me a habit of asking why a particular inverter had to be derated, or why one street had no room left for export while another a mile away did. Those questions were far more interesting than anything I could answer with the network diagrams I had at the time, and they shaped what I chose to study seriously.

My degree in electrical and electronic engineering gave me the tools to start answering them. I gravitated towards the power and machines modules: three-phase analysis, transformer and induction machine modelling, power electronic converters and control. My final-year project used an open-source load flow package to model voltage rise on a radial low-voltage feeder as photovoltaic penetration increased, testing how much difference a smarter inverter reactive power setting made compared with simply reinforcing the cable. The results were unsurprising to anyone in the field, but doing the work taught me a great deal: how sensitive the outcome was to the assumed load profile, how quickly a neat model becomes a set of judgements about data you do not have, and how much care is needed when presenting a result that depends on an unrepresentative summer day. I scored well on the project and, more usefully, finished it with a clear sense of what I had skated over. Unbalanced systems, fault level calculation, protection coordination and the economics of dispatch were all areas where I could follow an argument but not construct one.

Alongside coursework I have read fairly widely, if unevenly. Weedy's Electric Power Systems was my main reference during the project, and I have worked through parts of Kundur's book on stability, which showed me how much of the subject sits in the gap between machine modelling and control theory. I have also followed the Electricity System Operator's published reports on operating a zero-carbon system, which sharpened my interest in inertia, frequency response and the practical constraints that sit behind the modelling I did.

Since graduating I have worked part-time as a technical assistant in a college electronics workshop, preparing practical kits, testing equipment and supervising first-year students at the bench. Explaining an oscilloscope trace to someone seeing one for the first time has made me considerably clearer in my own explanations, and managing a stock of components and a repair backlog has taught me to plan work properly. My hobby of restoring old valve and transistor radios is related only loosely, but it has made me methodical about fault-finding and respectful of mains voltages.

I want to study power engineering at master's level because the questions I find interesting now require depth I do not yet have: distribution network modelling with real measurement data, converter-dominated system stability, and protection for networks with bidirectional flows. I would particularly like a dissertation involving network modelling or a hardware-based converter study. In the longer term I would like to work in distribution network planning or connections, where the analysis I enjoy meets decisions that people notice on their own streets.
