Fault Location on Compensated Transmission Lines without Current Measurement
This paper presents a novel fault location method for series compensated transmission lines. It is established based on synchronized voltages sampling and Thevenin impedance from both ends of series compensated transmission line. The method is based on the use of phasor measurement units (PMU) technology which is aimed to be independent of current measurements, fault type, fault resistance, fau...
متن کاملArcing Fault Detection and Fault Location on Hv Transmission Lines
In this paper a new numerical algorithm for fault distance calculation and arcing fault recognition, based on one terminal data and derived in the time domain, is presented. The algorithm is derived for the case of most frequent single-phase line to ground fault. The faulted phase voltage is modelled as a serial connection of the fault resistance and the arc voltage. The fault distance and the ...
متن کاملFault Location in Series Compensated Transmission Lines
Due to the integration of modern technology such as electric vehicles, the emphasis is expected to shift from mechanical to electric power. Therefore, the need of increasing the power transmission capacity of the electric grid gets highlighted. Since, the construction of transmission lines is a tedious task owing to legalities, environmental impacts and high costs, the series compensated transm...
متن کاملA Genetic Based Fault Location Algorithm for Transmission Lines
Overhead transmission lines are parts of the electric power system where fault probabilities are generally higher than that of other system components. One of the main objective of protective system is to detect faults on transmission lines as fast as possible. Another important job is to locate this fault point accurately. Therefore, it is very important to have a fast reliable methods that ca...
متن کاملFault Location on Transmission Lines Based on Travelling Waves
Automatic and accurate fault location methods for transmission lines may reduce the search time technicians would take to find out where the fault is, leading to a quick recovery of the system. Usually, transient detection techniques use more than one sample of voltage or current to make possible the required transient analysis. This paper presents a very simple method for fault location on tra...
