Abstract In order to eliminate the influence of delay error sampled value in data link on longitudinal differential protection device, this paper proposes a self-healing synchronization algorithm based wavelet transform calculate moment sudden change. First, mutation amount at each end real time. When threshold is exceeded, it determined that multi-terminal system has short-circuit fault. Then,...

Aiming at the fast and accurate location of a single-phase ground fault in distribution network, single terminal injection signal method, based on standing wave principle, is proposed. Firstly, double conductor principle formation, uniform transmission line theory, analyzed, mathematical model distance algorithm established. Secondly, detection circuit built by simulation, trend its relationshi...

Machine Learning (ML) approaches have a great impact in fault prediction. Demand for producing quality assured software in an organization has been rapidly increased during the last few years. This leads to increase in development of machine learning algorithms for analyzing and classifying the data sets, which can be used in constructing models for predicting the important quality attributes s...

This paper presents a five-phase fault-tolerant permanent-magnet synchronous machine (PMSM) used for electric vehicles. In multiphase fault-tolerant PMSMs equipped with fractional-slot concentrated windings, excessive magneto-motive force (MMF) harmonics can lead to thermal demagnetization of the permanent magnets (PMs). In order to reduce the lower-order harmonics, the origins of the 2-pole ha...

In this paper, we discuss an often-ignored, but very important issue, i.e., how to recover slow replicas quickly in a fault tolerant system. Despite the fact that the replicas are deployed in identicallyequipped computing nodes, under heavy load, some replicas would lag behind due to various reasons. Quickly recovering slow replicas is important because not doing so could result in reduced thro...

With the continuous miniaturization, electrical, high-speed and intelligent of railway signal equipment, the control switch module must have higher safety, reliability and anti-interference ability. Under this background, this paper studied the railway signal distributed computer control switch module. First of all, this paper introduced the main supporting technology of distributed interlockin...

In this paper a new test signal generation approach for general analog circuits based on the variational calculus and modern control theory methods is presented. The computed transient test signals also called test stimuli are optimal with respect to the detection of a given fault set by means of a predefined merit functional representing a fault detection criterion. The test signal generation ...
