Detection of Fault in Fixed Series Compensated Transmission Line during Power Swing Using Wavelet Transform
At the time of power swing the measured impedance lies inside the relay operating region. There is undesired tripping of Distance relay during power swing without having any fault. So relay must be blocked & must trip after a fault occur during power swing. This paper presents new technique to detect fault during power swing. In the proposed technique process starts by simulating the double tra...
متن کاملZero-setting Power-swing Blocking Protection
Modern distance relays have integrated numerous protection functions including power-swing blocking and out-of-step or pole-slip tripping functions. The main purpose of the power-swing blocking function is to differentiate faults from power swings and block distance or other relay elements from operating during stable or unstable power swings. Most power-swing blocking elements are based on tra...

15 صفحه اولUPFC Location and Performance Analysis in Deregulated Power Systems
We deal with the effect of Unified Power Flow Controller UPFC installation on the objective function of an electricity market. Also this paper proposes a Novel UPFC modelling in OPF which facilities the consideration of the impact of four factors on power market. These include the series transformer impedance addition, the shunt reactive power injection, the in-phase component of the series vol...
