Conclusion

Abstract

The aim of this work was to develop a fault locator system capable of locating faults with high accuracy on crossbonded cable systems and on hybrid lines. A two-terminal synchronised travelling wave method has been proposed and verified using field measurements conducted on the electrical connection to the offshore wind farm Anholt. The arrival instances of the fault waves are identified based on a combined visual inspection- and Wavelet based method. The proposed fault locator has been constructed based on the principles proposed and will be installed in Danish substations in the future for monitoring of the coming cable-based transmission grid. With the construction of the fault locator system, all problems formulated in the problem formulation are answered fully.
