Smoothing Reactor
Rated Voltage: Up to 1100 kV
Functional Overview
Connected in series with HVDC transmission lines, it serves in converter stations or back-to-back interconnects between power grids. Core functions include:
1.Suppressing harmonic currents (ripple reduction)
2.Limiting surge currents during faults
3.Controlling the rate of rise of DC phase current
4.Enhancing power system dynamic stability
