Low Voltage Direct Current (LVDC) distribution systems have recently been considered as an alternative approach to electrical system infrastructure they provide the additional flexibility and controllability required facilitate integration of more low carbon technologies (LCTs). However, DC protection and, specifically high accuracy fault location, recognised a key challenge facilitating post-f...

This paper deals with two of the main tasks of Fault Monitoring Systems (FMS): fault detection and fault identiication. During fault detection, the FMS should recognize that the plant behavior is abnormal, and therefore, that the plant is not working properly. During fault identiication, the FMS should conclude which type of failure has occurred. The rst goal of this work is to consolidate a ne...

Electric Vehicles (EVs) are an effective solution for reducing greenhouse gas emissions to the atmosphere. Safety is the most crucial issue in the automotive industry and any fault in the EV drivetrain may results in a fatal accident. This paper discusses the dynamic performance of EVs under drivetrain Voltage Source Inverter (VSI) switch faults and presents the suitable Fault Diagnosis Algorit...

Roberto Natella Università degli Studi di Napoli Federico II, Italy ABSTRACT This paper proposes an approach to software faults diagnosis in complex fault tolerant systems, encompassing the phases of error detection, fault location, and system recovery. Errors are detected in the first phase, exploiting the operating system support. Faults are identified during the location phase, adopting o...

Faulted lines must be repaired and returned to service in the shortest possible time to provide reliable service to the customers. Fault locators provide estimate for both sustained and transient faults. Transient faults cause minor damage that is not easily visible on inspection. Fault locators help identify those locations for early repairs to prevent recurrence and consequent major damages. ...

the nw-se trending zagros fold and thrust belt extends for about 1,800 km from a location some 300 km se of the east anatolian fault in ne turkey to the strait of hormuz where the north-south trending zendan-minab-palami fault system (zmp) separates the zagros belt from the makran accretionary prism. the ne limit of the zagros belt is marked by the main zagros reverse fault which is rotated abo...

The present paper presents an accurate hybrid framework capable to rapidly detect, classify & locate shortcircuit faults on transmission lines. The proposed algorithm has employed the values resulted from each threephase currents wavelet transform in order to obtain instantaneous fault detection. Singling out short-circuit faults based on the measured voltage waveforms and three-phase current i...

-This paper presents the consequences and operating limitations of installing distributed generation (DG) to electric power systems. The proliferation of new generators creates new operating conditions, some not seen before, that are limited by fault interruption capability. Increased system fault currents resulting from DG installation and the effects of increased fault currents are discussed....
