Model Structure Choice for a Static VAR Compensator Under Modeling Uncertainty and Incomplete Information

Static Var Compensator ( SVC ) for Offshore Applications

Static Equilibrium under Uncertainty and Incomplete Markets

1.1. The first model of general economic equilibrium was presented by Walras [15] more than hundred years ago. As the model became generally known, it must have been clçar that it was desirable to generalize it, and take uncertainty into account. The most visible markets at the end of the last century were probably the stock exchanges, where uncertainty obviously played an important part. Insur...

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...

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 ...
