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...

in this paper, a consistent pattern with the optimal coordinated design of pss and sssc controller to improve the damping of low frequency oscillations is shown. in this design, sensing and signal transmission time delays are considered as effectiveness parameters. the design problem has been considered an optimization problem and biogeography-based optimization (bbo) algorithm is used for sear...

Encountering series-compensated transmission lines, sub-synchronous resonance (SSR) may strike the power system by jeopardizing its stability and mechanical facilities. This paper aims to verify the capability of static synchronous series compensator (SSSC) in mitigating the mechanical and electrical oscillations such as SSR in wind farm integrations. A wind turbine with a self–excited inductio...

1892 All Rights Reserved © 2016 IJARCET AbstractThe power system industry is a field where there are constant changes occurs. Economic and environmental pressures force electric companies to enhance the power transfer capability of the existing transmission lines instead of constructing new ones. Besides allowing a better utilization of existing power systems capacity, FACTS controllers can con...

This report concentrates on presenting transient stability and power ow models of Thyristor Controlled Reactor (TCR) and Voltage Sourced Inverter (VSI) based Flexible AC Transmission System (FACTS) Controllers. Appropriate models for voltage and angle stability studies are discussed in detail for the Static Var Compensator (SVC), the Thyristor Controlled Series Compensator (TCSC), the Static Va...

For the power quality improvement of the system FACTS devices like static synchronous compensator (STATCOM), static synchronous series compensator(SSSC), interline power flow controller (IPFC), and unified power flow controller (UPFC) etc. are introduced. These devices are used for the transmission system. But now a day’s these FACTS devices are used for distribution system and called as custom...
