High-impedance faults (HIFs) caused by downed conductors in electric power systems are in general difficult to be detected using traditional protection relays due to small fault currents. The energized downed conductor can pose a safety risk to the public and cause a fire hazard. This paper presents a new method for locating the line (feeder) section of the HIF with the help of limited measurements in electric power systems. The discrete wavelet transform is used to extract the features of transients caused by HIFs. A modifiedk-means algorithm associated with genetic algorithms is then utilized to determine the placement of measurement facilities. The signal energies attained by wavelet coefficients serve as inputs to the support vector machine for locating the HIF line section. The simulation results obtained from an 18-busbar distribution system show the applicability of the proposed method.

Electric Aircraft

More Electric Aircraft (MEA), which is the developing trend of the next generation of aircraft, put forward high demands on the electric power system. Cyber-Physical Systems (CPS) are a kind of novel intelligent systems with computation resources and controlled physical objects tightly integrated and interacted in the future network environment. CPS have the characteristics of real-time, synchronous, security, efficient and autonomous. This paper first elaborates the notion, characteristics, operation mechanism and technical challenges of CPS. The strategy of CPS-based next aviation electric power systems is presented. Then, the architecture of aviation electric power cyber physical systems is established. Finally, key technologies of aviation electric power cyber physical systems, including data bus, control strategies, energy management, security analysis, modeling and simulation, standardized and so on, are discussed. And directions are pointed out to offer a reference for the application of CPS in aviation electric power systems.
