摘要
无功控制功能是特高压直流输电工程设计的重要组成部分,目的是满足换流站的直流系统无功需求、滤除交流侧谐波、保持交流侧母线电压稳定的要求。±800 k V普洱换流站是云广Ⅱ回特高压直流输电工程中的整流站,其直流站控系统中无功控制功能的电压有效性选择逻辑存在缺陷,文中提出了优化的措施,对特高压直流输电工程的可靠运行有着重要意义。
The purposes of reactive power control for UHVDC transmission project are to meet DC converter station＇s reactive power demand, filter harmonics at AC side, and keep AC side bus voltage stable. The ＋800 kV Pu＇ er converter station is in the Yun-Guang I1 UHVDC transmission project, however a flaw exists in voltage effectiveness selection logic of the reactive power control function of its DC station control system. This paper proposes optimization measures to eliminate this flaw, thus to benefit reliable operation of UHVDC transmission projects.
