This paper summarizes the priority level and logic of reactive power control in the dual circuit DC coordinated control of Niucong high-voltage DC transmission system,and proves the reason why the AC bus voltage switching reactive power compensation equipment takes priority over the absolute minimum filter capacity limit through simulation and on-site engineering practice.At the same time,compare the DC absolute minimum filter capacity limiting DC power strategy between Niucong high-voltage DC transmission system and Xindong ultra-high voltage DC transmission system,and pro-pose optimization suggestions.
