Popis: Thyristor Controlled Reactor (TCR) has been used to improve power quality through firing angle control by parallel connection to the system in the form of ∆-connection. The inductances of three-phase TCR are assumed to be a same value, but a difference is generated in the inductance value of each phase in the manufacturing process. Due to the difference in three-phase inductance, a conventional TCR control algorithm causes the imbalance of phase voltage. So, this paper proposes a method to solve the phase imbalance problem of TCR using a modified firing angle control scheme, and the performance of the proposed method was verified through Matlab simulation.
