High power-density fault-tolerant PM generator for safety critical applications
2013 International Electric Machines & Drives Conference, 2013Many safety-critical applications especially in aviation require high power (mass) density generators with high reliability. While PM machines promise significant improvements in power density, and reliability, the widespread use of permanent magnet (PM) generators has been hitherto limited by the potentially detrimental effect of internal machine ...

A General Approach for Fault Identification in SOFC-based Power Generation Systems
2018 Annual American Control Conference (ACC), 2018The design of fault identification method in fuel cells(FCs)-based systems remains a key challenge. This paper proposes a general data-based fault identification method using deep learning(DL). Because of the great success of deep learning in a variety of practical applications, it has recently become the most popular approach in machine learning. Deep

Aircraft Power Generators: Hybrid Modeling and Simulation for Fault Detection
IEEE Transactions on Aerospace and Electronic Systems, 2012Integrated drive generators (IDGs) are the main source of electrical power for a number of critical systems in aircraft. Fast and accurate fault detection and isolation (FDI) are necessary components for safe and reliable operation of the IDG and the aircraft.

Fault diagnosis of automotive electric power generation and storage systems
2010 IEEE International Conference on Control Applications, 2010Automotive vehicles are becoming increasingly dependent on electric power, and this trend will accelerate. The health of the vehicular electric power generation and storage (EPGS) system is crucial to enhance vehicle safety, fuel economy, and reliability. In this paper, a fault detection and isolation method is presented for the automotive EPGS system,

An analysis of open-phase fault in power generation station
2016 North American Power Symposium (NAPS), 2016This paper attempts to investigate and analyze the electrical characteristics present on the power grid when an open-phase event occurs at an off-site transformer. In order to conduct such task, this paper uses transformer, load, and connection data obtained from a real power plant to simulate several different power system configurations and analyzes ...

Analysis of Power System Faults by Phase Impedance Matrix Method: I - General Fault Analysis
IEEE Transactions on Power Apparatus and Systems, 1972The analysis of unbalanced power systems depends usually on transformation methods by which the phase quantities are substituted by, for example, symmetrical component quantities. These transformations had the computational advantages in the past, but with the use of digital computer, they no longer appear to be necessary. In this paper the analysis of
