Abstract

The discriminating logic of DC station control system for AC filter on and off states in the YunnanGuangdong UHVDC system is analyzed in detail

and is compared with corresponding logics of other HVDC converter stations. Examples are taken for the analysis. As a result

design defect is found in the logic

which may cause misjudgment of the AC filter on and off states by the DC station control system and further affect the system’s reactive power control. Consequently

corresponding countermeasures are offered

which are also suitable for other converter stations.
