Voltage Stability Improvement using Static Var Compensator in Power Systems

This paper investigates the effects of Static Var Compensator (SVC) on voltage stability of a power system. The functional structure for SVC built with a Thyristor Controlled Reactor (TCR) and its model are described. The model is based on representing the controller as variable impedance that changes with the firing angle of the TCR. A Power System Computer Aided Design /Electromagnetic Transi...

Optimal Operation of Doubly-fed Induction Generator used in a Grid-Connected Wind Power System

In this paper, a wind power system based on a doubly-fed induction generator (DFIG) is modeled and simulated. To guarantee high-performance control of the powers injected into the grid by the wind turbine, five intelligent super-twisting sliding mode controllers (STSMC) are used to eliminate the active power and current ripples of the DFIG. The STSMC controller is a high-order sliding mode cont...

Static Var Compensator ( SVC ) for Offshore Applications

Design of Microcontroller Based Static VAR Compensator

The change in system voltage and frequency with changing load creates problem in power system stability. For the sake of system stability and reliability, the reactive power compensation is essential for flexible AC transmission system (FACTS). The variation of reactive power causes impact on the generating units, lines, circuit breakers, transformers, relays and isolators. However the reactive...

Aspects concerning the Static Var Compensator

The paper presents some considerations regarding the structure and behaviour of the static var compensator (SVC). Thus, starting from a structure of the compensator it determinates the fundamental impedance of the SVC and it analyses the dependence of the impedance v.s. the components elements (C, R, Lc). Also, it has been realised and the analyses regarding the overvoltages which can appears o...
