Fault Location on transmission feeders using travelling waves, transients and power frequency signals (FULLY FUNDED)
Planning constraints restrict the construction of new overhead lines, but undergrounding a transmission feeder is normally financially unaffordable. The compromise solution is to bury sections of the overhead feeder where environmental, visual or technical restrictions apply or where it enters an urban area. Economic constraints also restrict the building of new substations and a lower cost option can be the direct Tee connection of a new feeder to an existing overhead line.
Fault location on an overhead line with cable sections, or on a Tee circuit, is a difficult problem that requires new hybrid solutions that utilise the advantages of travelling wave, transient and power frequency fault location techniques in conjunction with advanced signal processing algorithms. The research will first investigate the accuracy and reliability of double-ended and single ended travelling wave (TW) based fault locators and assess if their performance can be improved by analysing the signals using hybrid solutions with new processing algorithms. As confidence increases in the capabilities of the new algorithms, a prototype hybrid fault locator will be constructed and evaluated.
