Abstract—Static VAR System (SVS) is a kind of FACTS device which is used in power system primarily for the purpose of voltage and reactive power control. In this paper presents a systematic approach for designing SVS supplementary controller, which is used to improve the damping of power system oscillation. The combined bus voltage and line current (CBVLC) supplementary controller has been deve...

When power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. Therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. SSSC is a FACTS device con...

This paper proposes an approach for the protection of transmission lines with FACTS based on Artificial Neural Networks (ANN) using Wavelet Transform (WT). The required features for the proposed algorithm are extracted from the measured transient current and voltage waveforms using discrete wavelet transform (DWT). Those features are employed for fault detection and faulted phase selection usin...

Recent investigations have focused on the use of active phase imbalance schemes using series connected FACTS devices for subsynchronous resonance (SSR) and power swing damping. This paper compares the effectiveness of TCSC and SSSC based single phase compensation schemes with the corresponding three phase schemes. Controllability of swing modes as well as torsional modes is compared by using a ...

This work describes the design of a DSP (Digital Signal Processor) based Adaptive Numerical Mho relay, to be used for distance protection schemes of long distance transmission lines. The relay settings will be automatically adjusted with the changes of power system parameters with the variation of frequency as well as with the variation of percentage compensation which may occur due to fault /d...

A left-handed transmission line with regularly spaced Schottky varactors is experimentally characterized. Due to dispersion, an envelop pulse on the line experiences a great distortion. By measuring the test line, we successfully observed that this distortion is compensated for by the nonlinear effects of Schottky varactors. This article describes the experimental observations, together with fu...
