This study proposes an intelligent protection relay design that uses artificial neural networks to secure electrical parts in power infrastructure from different faults. Electrical transformer and transmission lines are protected using differential distance relay, respectively. Faults categorized, their locations pinpointed three-phase current values zero-current characteristics differentiate b...

Modern spectral and harmonic analysis is based on Fourier transforms. However, these techniques are less efficient in tracking the signal dynamics for transient disturbances. Consequently, the wavelet transform has been introduced as an adaptable technique for non-stationary signal analysis. Although the application of wavelets in the area of power system engineering is still relatively new, it...

The turn-to-turn short is one major fault of the motor faults of BLDC motors and can appear frequently. When the fault happens, the motor can be operated without breakdown, but it is necessary to maintain the motor for continuous working. In past research, several methods have been applied to detect winding faults. The representative approaches have been focusing on current signals, which can g...

The location of ground faults in railway electric lines in 2 × 5 kV railway power supply systems is a difficult task. In both 1 × 25 kV and transmission power systems it is common practice to use distance protection relays to clear ground faults and localize their positions. However, in the particular case of this 2 × 25 kV system, due to the widespread use of autotransformers, the relation bet...

<span lang="EN-US">In this paper we propose a strategy for real-time detection of interturn short-circuit faults (ISCF) on three-phase induction motor (IM) by using Vold-Kalman filter (VKF) algorithm. ISCF produce thermal stress into the stator winding due to large current that flows through short-circuited turns. Therefore, incipient fault is required in order avoid catastrophic failures...

For sustaining in the era of globalization, frequent up-gradation in the software is demanded. In order to maintain the competitive edge firms come up with highly reliable versions. For providing high reliability firms have to test software rigorously that requires debugging the software in the testing as well as in the operational phase. Upgrading the software leads to the enlarged complexity ...

This paper proposes a method of eliminating common-mode voltage (CMV) and shaft in dual three-phase motors using the carrier phase shift space vector pulse width modulation (SVPWM). SVPWM for motor is simply implemented two traditional structures. The representative work study to eliminate by applying due cancellation CMV. It was verified that proposed could reduce with simple technique, rather...

This paper studies fault-tolerant operation of multipole single-phase switched reluctance generators (SRG’s), in particular, an 8/8-pole switched reluctance machine. The multipole single-phase SRG system is advantageous for reduced cost and higher efficiency compared to polyphase equivalents. However, using the classical phase-leg topology, a phase fault may prevent generating operation complet...

Multi-phase motors and generators are regarded with great fault tolerance capability, especially on open-circuit faults. Various mathematics analytical methods applied for their control. In this paper, a fault-tolerant control strategy asymmetric phase current the faults arbitrary phases in six-phase PMSM (six-phase permanent magnetic synchronous motor, 6P-PMSM) system, is proposed better elect...
