The effect of line impedance compensation mode of series inverter along with the voltage regulation mode of shunt inverter of UPFC is investigated for transient stability improvement of Single Machine Infinite Bus System. Four control modes like perpendicular voltage or phase angle control etc have also been discussed. The effect of line impedance mode on critical clearing time with a three pha...

Distribution networks frequently experience cross-country failures (CCFs).This study presents research that demonstrates how Cross-Correlation may be used to extract distinctive features from faulty current signals, hence providing a threshold-based technique for fault identification. The most challenging aspect of dealing with HIF syndrome-related CCFs is recognizing and categorizing them. In ...

An interturn short-circuit fault in the stator winding of an electric machine, denoted as turn fault, has been recognized one most severe faults permanent magnet machines, which require a swift and reliable detection, order to implement appropriate mitigations. The asymmetry brought by is widely used for detection. However, similar features also emerge less high-resistance connection (HRC) may ...

Accurate faulty phase detection under single-line-to-ground (SLG) fault is the basis of emerging voltage-based arc suppression technology. Most conventional recognition criteria assume distributed line-to-ground parameters are symmetrical, therefore suffering invalidity in actual distribution networks especially high-resistance ground-fault conditions. This paper firstly analyzes magnitude and ...

In this paper, an application of superconducting fault current limiter (SFCL) is proposed to limit the fault current that occurs in power system, SFCL is a device that uses superconductors to instantaneously limit or reduce unanticipated electrical surges that may occur on utility distribution and transmission networks. Due to the difficulty in power network reinforcement and the interconnectio...

This paper addresses the problem of fault diagnosis in a robotic manipulator designed for human interaction. Faults in the external force sensor are addressed with a constant or slowly time-varying profile. A model-based strategy is considered that takes into account uncertainty in the mathematical representation, where a proportional-integral (PI) observer is in charge of estimating the fault ...

The distribution feeder faults need to be detected and isolated in a reliable Maintenance and operation of a distribution type electrical power system, calls for a safe, reliable and efficient fault detection systems. As the number of techniques available to detect faults do not address the above concerns in to-to, especially in the case of a High Impedance Faults. Keeping in view of aforesaid ...

Certain level of mechanical deformations in winding does not hamper the normal performance of power transformer. However, such incipient deformations if unattended could result in permanent failure of transformer. To this end, an approach is proposed to assess the severity of mechanical deformations in transformer winding. These deformations get reflected as changes in its high frequency behavi...

A fault current limiter (FCL) may be applied to assist the low-voltage ride-through (LVRT) of a doubly fed induction generator (DFIG). FCLs with fixed impedance, lack flexibility adjust their impedance adapt different LVRT scenarios. The direct switch-in and -out fixed-impedance FCL yields transient electromagnetic oscillations in DFIG, which need addressed. In this paper, variable-impedance is...

Fault location has been studied deeply for transmission lines due to its importance in power systems. Nowadays the problem of fault location on distribution systems is receiving special attention mainly because of the power quality regulations. In this context, this paper analyses the influence of the capacitance of cables and compensation capacitor banks when impedance-based algorithms are use...
