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...

Static Synchronous Compensator (STATCOM) can improve power factor and dynamic stability on power system. STATCOM is Multiple Input and Multiple Output (MIMO) system, which can be presented by a mathematical model. This paper presents an application of Particle Swarm Optimization (PSO) as a modern tool to design controller parameter of weighting matrices Q and R of the LQ optimal control to obta...

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...

This paper presents transient stability and power flow models of static synchronous compensator (STATCOM) and current Sourced Inverter (CSI) based Flexible AC Transmission System (FACTS) Controllers. A model of the static synchronous compensator (STATCOM), the application of the static synchronous compensator (STATCOM) in improving transient stability in power systems.MATLAB/SIMULINK is used to...

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...

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...

using the facts controllers, such as static synchronous compensator (statcom), as it provides continuous reactive power, in the grid including wind turbine (wt) equipped with doubly fed induction generator, for improving voltage profile (under normal circumstances) and providing a transition ability from inductor generator transition state has been proposed. in this paper, in order to control t...

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...
