摘　　要：随着我国电力规模的快速发展,全国直流输电工程大幅增加。在传统的换流站电压控制中,交流滤波器起到十分重要的无功控制作用,但随着新能源的发展,换流站开始加装调相机,以期获得更加优良的无功调节性能。文章首先阐述了调相机控制措施和交流滤波器控制措施,其次介绍了无功功率协调控制措施,最后进行了仿真试验分析,包括无功率平衡控制试验、交流系统故障试验和直流系统故障试验。结果表明,这些措施可以使换流站具备高度协调控制的能力,促进直流输电工程高效运行,并在遇到故障时可以快速恢复。With the rapid development of China's power scale,the national DC transmission project has been increased significantly.In the traditional voltage control of converter stations,AC filters play a very important role in the reactive power control.However,with the development of new energy,converter stations begin to install condensers in order to obtain more excellent reactive power regulation performance.The article firstly describes the control measures of the synchronous condenser and AC filter,and then,introduces the coordinated control measures of the reactive power.Finally,the simulation test analysis is carried out,including the powerless balance control test,AC system fault test and DC system fault test.The results show that these measures make the converter station to have a highly coordinated control capability,promote the efficient operation of the DC transmission engineering and be capable of rapid recovery when faults are encountered.
