Reactive Compensation Capability Of Fixed Capacitor Thyristor Controlled Reactor For Load Power Factor Improvement: A Review
نویسندگان
چکیده
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 by appropriately changing the firing angle of the TCR circuit in lagging as well as the leading power factor range. The application of fuzzy logic for the controlling of the FC-TCR system to improve the load power factor is also being discussed.
