摘　　要：梳理牛从高压直流输电系统双回直流协调控制中无功控制优先等级及其逻辑,结合仿真和现场工程实际情况证明交流母线电压投切无功补偿设备优先于绝对最小滤波器容量限制的原因。同时,对比牛从高压直流输电系统直流与新东特高压直流输电系统直流绝对最小滤波器容量限制直流功率策略,并提出优化建议。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 propose optimization suggestions.
