Algorithm for the Optimal Design of a Fault-Tolerant Aircraft Power Transmission Network

IEEE Transactions on Transportation Electrification, 2022
Aircraft manufacturers aim to decrease the fuel consumption based on reducing weight and increasing the subsystem efficiency. Hence, the electric power system (EPS) acquires great relevance because it must be efficient and lightweight. Any change in the EPS must not affect the aircraft’s electrical safety, which under a traditional decentralized EPS ...

Arcing Faults Location Methods for Power Transmission Lines

Acta Energetica, 2014
This paper presents three different fault location approaches: one-end Takagi algorithm, two-end algorithm considering natural fault loops and neural network. It is assumed that three-phase voltages and currents from both ends of the line measured asynchronously are the input signals of the fault locator.
