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...

Optimal Location of Static Var Compensator Device for Damping Oscillations

Problem statement: Static Var Compensators (SVC) devices are used to improve voltage and reactive power conditions in AC systems. An additional task of SVC is to increase transmission capacity as result of power oscillation damping. The effectiveness of this controller depends on its optimal location and proper signal selection in the power system network. A residue factor had been proposed to ...

A Microcontroller-based Static Var Compensator for Unbalanced Loads

The authors report the development of the laboratory model of a microcontroller-based Static Var Compensator (SVC). A prototype of an automatically controlled voltage balancer using thyristors valves to switch the capacitors and inductors has been investigated. A digital control scheme incorporating a microcontroller is developed. At each sampling time, the loading conditions are measured by a ...
