The dual characteristics of phase control reactor controlled series compensation and phase control capacitor controllable series compensation are revealed. The dual-phase principle is used to describe the performance and phase-control characteristics of the controlled-series compensation of the phase-controlled capacitor. The relationship between the peak value of current and voltage of series compensation capacitor and GTO valve, the peak value of series compensated line current and the tolerance of power factor of series compensation capacitor is analyzed and analyzed. It is of great value to theoretically confirm the controllable series compensation of phase control capacitor Very important. The controllable series compensation of phase-controlled capacitor has the ability of damping sub-synchronous resonance and suppressing low frequency power oscillation. The dynamic performance of the controlled-rectifier series compensation device of phase-controlled reactor is a time constant not more than 0.225 cycles First-order inertia
