Despite recent advances in power system protection technologies over the last decade, existing protectivex000D
relays still operate only after a fault disrupts the healthy operation of a power system component. Therefore, thex000D
protection technology has remained reactive in nature. This approach has a limit for reducing the outage timex000D
and increasing the reliability of the grid. This project through a partnership between Professor Ali Hooshyarx000D
and partner organization, Hyperion Sensors, will attempt to fundamentally change this approach and developx000D
protection technologies that predict a future failure in a power system component, e.g., an underground cable orx000D
a transformer winding. Therefore, the necessary maintenance to remove the root cause of that fault can bex000D
carried out before the end users experience power outage. The technique adopted by Hyperion Sensors tox000D
implement this approach is based on distributed measurement of mechanical quantities (such as, temperaturex000D
and pressure) using a network of optical fibre. The optical fibre is distributed spatially alongside different partsx000D
of the power equipment, and operates both as the sensor and the communication medium to transfer thex000D
measured quantities. The optical fibre can measure, e.g., temperature through a variety of principles, such asx000D
Brillouin principle.x000D
The challenges that are to be met for the realization of this technology are (i) identifying the appropriatex000D
mechanical quantity measured by the optical fibre, and (ii) finding the patterns in the measured quantities thatx000D
can be used to predict a future failure. Hyperion Sensors is acquiring its first set of temperature measurementsx000D
for an underground cable. The company will provide the data to the applicant to investigate differentx000D
waveshape recognition and artificial intelligence techniques that can be used to address the above challenges.x000D
These techniques will be implemented in the protective device developed by Hyperion Sensors. Such ax000D
protective device will reduce the outage time and increase the reliability of the power grid.
