| Abstract: |
| Damping type double tuned AC filter is the most common filter in HVDC system, and its optimal design is related to the performance and value adjusting of AC filter. The harmonic current split ratio expression of double tuned AC filter is derived based on the impedance-frequency characteristics expression of double tuned AC filter with different damping resistances, and the effect of damping resistance on AC filter’s performance and value adjusting is further analyzed. The relationship between the damping resistance and THFF is derived, and the impact expression of the damping resistance on AC filter’s value adjusting and cost is derived, providing the optimization calculation basis of double tuned AC filter. The algorithm and flowchart of optimization design are summarized. |
