Switching Time Bifurcations in a Thyristor Controlled Reactor

Thyristor controlled reactors are high power switching circuits used for static VAR control and the emerging technology of flexible ac transmission. The static VAR control circuit considered in the paper is a nonlinear periodically operated RLC circuit with a sinusoidal source and ideal thyristors with equidistant firing pulses. This paper describes new instabilities in the circuit in which thy...

Reactive Compensation Capability Of Fixed Capacitor Thyristor Controlled Reactor For Load Power Factor Improvement: A Review

Reactive power compensation capability of a fixed capacitor thyristor controlled reactor type static VAr compensator is being investigated in this paper. The TCR has the power transfer controlling capability only in the lagging power factor range. The range of TCR can be extended by connecting a fixed capacitor in shunt with the TCR. The compensated reactive power can be selectively controlled ...

Application of thyristor-controlled series reactor for fault current limitation and power system stability enhancement

Various types of Fault Current Limiters (FCLs) have been proposed and proven to offer numerous advantages with respect to transmission losses, voltage quality, and power system stability. However, FCL research has largely focused on only the FCL system, including optimization of components, efficiency improvement, and cost reduction. Conventional solutions to fault current problems, such as spl...

Power filtering method with controllable inductance for eliminating thyristor rectifier load harmonics

In this paper, we propose a Controlled Inductance Power Filter (CIPF) to solve power quality problems in industrial DC power supply systems. This method is based on the theory of magnetic potential equilibrium combined with active hybrid filter technology. Initially the system structure and filter wiring scheme are presented and the equivalent circuit is performed with the mathematical models o...
