Superconductor fault current limiter (SFCL) is an effective device to suppress high fault currents. This paper presents a comparative study of resistive and inductive fault current limiters from transient stability point of view.  Appropriate location and type of the limiters in a HV substation is selected by a qualitative approach based on the equal area criterion. Study system is simulated by...

Along with the increasing the level of distribution network intelligence and the network complexity, the automatic fault location technology for distribution network is particularly important. But the traditional fault location methods based on one information source is impossible to locate the faults accurately because of there are losses or faults in the information from the distribution. So,...

The problem of fault location has been studied deeply for transmission lines due its importance in the power system. Nowadays the problem of fault location on distribution systems is receiving special attention mainly because of the power quality regulations. This paper presents some of the most relevant methods for fault location in radial power systems. Additionally here is presented an hybri...

Overhead transmission line is the main way of power transmission, and its safe stable operation particularly important. Due to complex network, distance, large voltage grade serious problems such as frequent failure, this paper breaks through fault location traditional single, set induction electric wires, location, insulation monitoring technology at an organic whole, developed abnormal diagno...

Overview of fault location techniques for HV (EHV) transmission lines as well as for distribution networks is presented. One-end and two-end fault location for traditional uncompensated transmission lines is considered first. The presented two-end fault location is based on unsynchronised measurements at the line terminals. Then the technique with phase co-ordinates approach is utilised for loc...

An approach for assignment of the optimal location and tap changer adjustment related to flux-lock type superconducting fault current limiters with tap changer (TC-FLSFCL) is used in this paper by debating the reduction of fault current flowing from each device and enhancement of reliability varying with customer type in a distribution network connected with distribution generation (DG). TC-FLS...

In this paper, the effect of number and fault current limiter(FCL) location has been investigated in order to have maximum reduction of short circuit current level in all buses in a real network. To do so, the faulty buses were identified in terms of short circuit current level by computing short circuits on the desired network. Then, while the fault current limit was modeled, its optimal locat...

This paper deals with fault location on three-terminal power line. The fault locator is considered as associated with the line protective relay, which communicates with the relays from the remaining line terminals and receives from them the phasors of measured threephase currents. Three subroutines of the fault location algorithm are formulated and an issue of selecting the subroutine, which is...
