| Abstract |
The control method of Thyristor Controlled Reactor(TCR) is described in this paper for compensating the poor power factor, unbalanced and/or nonlinear load. Also, auxiliary controller such as DC current and power-factor controller is described. The reference current of TCR is calculated from the active and reactive Current components for each of the positive and negative sequence components in the load Currents. This reactive power control technique was verified by simulation program and will be used in 5Mvar TCR system, which will be installed next year at hot rolled mill at POSCO, located in Kwang-Yang. |
