Fault diagnosis scheme for open-circuit faults in field-oriented control induction motor drives
(The Institution of Engineering and Technology, 2013-05)
In this study, a new model-based fault detection and isolation (FDI) strategy is proposed for field-oriented control (FOC) induction motor (IM) drives. Actuator faults are addressed, and specifically, single open-circuit ...
Open-Circuit Fault Identification Method for Interleaved Converters Based on Time-Domain Analysis of the State Observer Residual
(Institute of Electrical and Electronics Engineers, 2018-07-05)
Fault-tolerance capability is a critical matter in power conversion systems that require continuous operation. Multiphase converters provide an inherent redundancy that gives them fault-tolerant capability. In addition, ...
Power saving and fault-tolerance in real-time critical embedded systems
(Elsevier Science, 2009-02)
In this paper, a method with the double purpose of reducing the consumption of energy and giving a deterministic guarantee on the fault tolerance of real-time embedded systems operating under the Rate Monotonic discipline ...
Open- And short-circuit fault identification for a boost DC/DC converter in PV MPPT systems
(MDPI, 2018-02)
This paper proposes a fault identification system for short and open-circuit switch faults (SOCSF) for a dc/dc converter acting as a Maximum Power Point Tracker (MPPT) in Photovoltaic (PV) systems. A closed-loop operation ...
A novel approach to arcing faults characterization using multivariable analysis and support vector machine
(MDPI, 2019-06)
Based on the Institute of Electrical and Electronics Engineers (IEEE) Standard C37.104-2012 Power Systems Relaying Committee report, topics related to auto-reclosing in transmission lines have been considered as an imperative ...
High-speed directional protection without voltage sensors for distribution feeders with distributed generation integration based on the correlation of signals and machine learning
(Elsevier Science SA, 2020-03)
This paper proposes a novel methodology to define fault current direction along the Distribution Feeder (DF) considering Distributed Generation (DG) integration. The proposed methodology is based on Empirical Decomposition ...
Fault diagnosis in grid-connected PV NPC inverters by a model-based and data processing combined approach
(IET, 2019-10)
This paper presents a fault detection and isolation (FDI) method for open-circuit faults (OCF) in the switching devices of a grid-connected neutral-point-clamped (NPC) inverter for photovoltaic (PV) applications. The ...
Multiple resonant controllers strategy to achieve fault ride-through and high performance output voltage in UPS applications
(Institution of Engineering and Technology, 2018-12)
A control strategy to achieve fault ride-through capability and to provide high performance of the output voltage of a single-phase uninterruptible power supply (UPS) inverter is proposed in this study. This strategy ...
