Modified thyristor controlled reactor for static VAR compensators

This paper provides new thyristor controlled reactor (TCR) used for static VAR compensator (SVC). The concept of this modified thyristor controlled reactor MTCR depends on modifying the waveform of the developed current by adding auxiliary circuit. The auxiliary circuit consists of back-to-back thyristors, inductor and capacitor. The developed current be the MTCR has less harmonic content. This paper explains the principle of MTCR and the parameters affects its operation. The MTCR enables to get lower current harmonic which enhances the SVC performance and reduce the cost of required filter.
