General-compensation-purpose Static var Compensator prototype

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...

Static Var Compensator ( SVC ) for Offshore Applications

Design, Fabrication and Implementation of Microcontroller Controlled Static Var Compensator

Power factor correction is vital in present society. The two key benefits of power factor correction, which includes reduced power costs and higher system capacity. Implementation of Flexible AC Transmission Systems (FACTS) improves the power factor, power transfer capability and voltage stability. The shunt type of FACTS controller is used to either absorb or inject VARs into the system, there...

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...
