The Advanced Sensors Team within the Institute for Energy and Environment at the University of Strathclyde, Glasgow, Scotland, has been involved in photonic sensors research with the key objective to harness the benefits of fibre optic sensing and develop solutions for specific measurement problems within power and energy sectors. The team has carried out a unique portfolio of research programmes, mainly focussing on spectrally encoded sensors, and addressing such issues as sensor design, fabrication, packaging, deployment, and interrogation.
This presentation will highlight specific examples of the measurement needs within the power and energy sectors and report on our recent progress in the established and novel approaches in fiber sensing to address these needs. In particular, I will discuss such applications as downhole and subsea electrical plant monitoring; voltage and current measurement for power system protection in the context of distributed generation; force and magnetic field monitoring in the context of thermonuclear fusion research; and, measurement of the loss of loading within concrete prestressing steel tendons in nuclear power plant applications. As the potential good solutions to these respective measurement needs, I will introduce and discuss such emerging technologies as the hybrid FBG voltage and current sensors; novel FBG interrogation schemes utilizing WDM and TDM architectures, not requiring tunable spectral filters or lasers; and novel FBG sensors and interrogation schemes utilizing some promising intrinsic sensing mechanisms capable of measuring such quantities as magnetic and electric fields or bend.
