The design and testing of both a TSR-based SVC and a TCR-based SVC are accomplished in the Power Systems Research Laboratory of Nigde University. The TSR-based SVC and TCR-based SVC devices are studied in three-bus and single machine infinite bus systems for three-phase static load conditions. The effects of TSR-based SVC and TCR-based SVC devices on load voltages are also analyzed. Experimental results show that significant improvement in reactive power compensation and voltage regulation is achieved by using TSR-based SVC and TCR-based SVC.eninfo:eu-repo/semantics/closedAccessFlexible AC Transmission Systems (FACTS)Thyristor Switched Reactor-Based Static VAr CompensatorThyristor Controlled ReactorVoltage RegulationCompensationArticle18214715710.3906/elk-0907-1382-s2.0-77949505050Q396728WOS:000277173800001Q4
