Fault diagnosis in transmission lines constitutes a problem in power systems with relevant technical and economic impact for independent system operators and also for the asset owner itself. Several techniques have been proposed in the literature to deal with this problem in a significant number of applications. This survey presents the main research areas and the trends in transmission line fault...
This paper proposes new method of monitoring and fault detection in photovoltaic systems, based mainly on the analysis of the power losses of the photovoltaic system (PV) by using statistical signal processing. Firstly, real time new universal circuit based model of photovoltaic panels is presented. Then, the development of software fault detection on a real installation is performed under the MATLAB/Simulink...
Software-based self-test (SBST) is increasingly used for testing processor cores embedded in SoCs, mainly because it allows at-speed, low-cost testing, while requiring limited (if any) hardware modifications to the original design. However, the method requires effective techniques for generating suitable test programs and for monitoring the results. In the case of processor core testing, a particularly...
In this paper, a new technique of on-line detection of inter-turn short circuits in stator of permanent magnet synchronous motor (PMSM) is proposed. The study is focused on a PMSM with non sinusoidal electromotive force (emf). The technique is formulated by combining extended Parkpsilas vector approach and classical recursive least squares algorithm (RLS). The faults are detected by analysing the...
