When a short-circuit fault with transition resistance occurs on a transmission line, it is difficult to derive the distribution coefficients if both ends of the transmission line are not synchronous. So, for the distance protection and fault location device, it is difficult to give an accurate analytical expression for the impedance measurement. For this problem, this paper aiming at the two-phase...
This paper presents an adaptive distance protection in the presence of Static Synchronous Series Compensator (SSSC), one of the series connected Flexible Alternating Current Transmission System (FACTS) devices. The presence of SSSC on a transmission line has a great influence on the measured impedance at the relaying point. The measured impedance itself depends on the power system structural conditions,...
Based on Wide Area Measurement System (WAMS), a new method for live line measuring the impedance parameters of transmission lines with mutual inductance is proposed. The mathematical model of the new method is explained in detail. The new method uses no extern voltage source and it only uses the zero-sequence interference voltages among the transmission lines as the measurement sources. The hardware...
Based on GPS technology, a new differential equation method (DEM) of live line measuring the parameters of transmission lines with mutual inductance is proposed. The new method uses only the inductance voltages or inductance currents between lines as the measurement sources. No extern voltage source is applied in measurements, so this method can also be called as an interference measurement method...
This paper discusses the distance relay ideal tripping characteristic in the presence of static synchronous series compensator (SSSC), one of the series connected flexible alternating current transmission system (FACTS) devices, on the next line, in the case of inter phase, phase to phase and three phase, faults. Especial attention is paid to the over-reaching problem. This is done by presenting the...
Thh paper discusses a distance relay mal-operation in the presence of Static Synchronous Series Compensator (SSSC), one of the series connected Flexible Alternating Current Transmission System (FACTS) devices, in the case of inter phase, phase to phase and three phase, faults. This is done by presenting the measured impedance at the relaying point in the presence of SSSC at the near end of the line...
