An Improved Double Connected Voltage Source Inverter for a Static Var Compensator.

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...

Voltage Collapse Prediction and Voltage Stability Enhancement by Using Static Var Compensator

Voltage instability is gaining importance because of unusual growth in power system. Reactive power limit of power system is one of the reasons for voltage instability. Preventing Voltage Collapsesare one of the challenging tasks present worldwide.This paper presents static methods like Modal Analysis, Two Bus Thevenin Equivalent and Continuation Power Flow methods to predict the voltage collap...

A practical approach to switching-loss reduction in a large-capacity static VAr compensator based on voltage-source inverters

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...
