| Abstract |
The design of harmonic AC-filters for an HVDC converter station connected to a weak AC-system has to consider both steady state and transient performance requirements. For weak AC-systems, the dynamic (DOV) and saturation (SOV) overvoltages after load rejection are considerably high. DOV-overvoltages can be reduced by SVC (TCR). Saturation overvoltages can be damped by using appropriate AC-filters with damping effect at low-order harmonics. The paper shows the comparison between configurations of AC-filters and SVC in damping these overvoltages after load rejection. The AC-system is chosen to be resonant with the connected AC-filters near the 3rd harmonic. The objective is to reduce the overvoltages on the AC-busbar below the design value of existing breakers to allow switching off sub-banks. |
