순차 프리에 변환(DFT)를 이용한 전압비교형 TCSC TCSC(Thyristor Control led Series Compensation)

Voltage Comparison-type TCSC Using Recursive Discrete Fouier Transform

We have proposed a new technology compensating reactance component of line and load. Because capacity of SC is static, it is not appropriate to varing reactance and causes SSR problems. TCSC is introduced for the flecxible control of reactance of SC. If SC voltage is varied when the capacitor current is constant, it can be considered that capacity of SC was varied. SO capacity of SC can be controlled by controlling the voltage of SC. Control reference voltage of SC can be obtained from the condition that sum of reactive powers in all parts is zero.
