Increasingly more electrical devices are being developed in modern aircraft and will result in an increase in airborne electronic equipment fed by power electronic converters. With aircraft power system being sizable, the logical structure of aircraft power distribution systems, which affects the stability of aircraft power system, is becoming more complex. In this paper, we establish a mathema...

Electrical power distribution systems are composed of heterogeneous components, which include continuous power sources, discrete relays, passive and active loads, and fastswitching power conversion subsystems. This heterogeneity introduces significant challenges for model-based diagnosis, such as building accurate models, and generating fast and accurate diagnoses while ensuring robustness to m...

Because of the product variety and structure complexity of the engineering machinery, it was difficult to meet the requirements of fault detection and maintenance for the traditional diagnosis technologies. In order to improve the diagnostic level, the intelligent control technology of neural network and its application in engineering machinery fault diagnosis were studied. The basic concepts o...

Motor electrical current signature analysis (MCSA) is sensing an electrical signal containing current components that are direct by-product of unique rotating flux components. Anomalies in operation of the motor modify harmonic content of motor supply current. This paper presents brief introductory review of the method including fundamentals, fault detection techniques and current signatures of...

The mathematical modeling of open-switch faults in two-level machine-side converters and the fault-tolerant current control of isotropic permanent-magnet synchronous generators are discussed. The proposed converter model is generic for any open-switch fault and independent of the operation mode of the electrical machine. The proposed fault-tolerant current control system gives improved control ...

On the basis of farther research about characteristics of single-phase-to-ground fault transient information in neutral indirectly grounded systems and feature information which is abstracted from transient fault signals by wavelet, a novel fault line identifying method using signal singularity detection with the wavelet transform modulus maxims is presented in this paper. A new criterion is co...
