[Abstract]:Damping double tuned AC filter is the most commonly used filter in HVDC transmission system. Its optimal design is related to the performance and fixed value of AC filter. Based on the unified resistance characteristic expression of double-tuned filter with damping resistor at different positions, the shunt ratio expression suitable for double-tuned filter is derived, and the influence of damping resistance on the performance and fixed value of AC filter is further analyzed. The relationship between the damping resistance and the harmonic wave coefficient of telephone is analyzed, and the formula of the influence of damping resistance on the fixed value and cost of AC filter equipment is derived, which provides the basis for the optimization design of the damping double-tuned AC filter. Finally, the algorithm and flow of optimization design are summarized.
