摘　　要：在贵广II回直流输电系统的无功控制,相较天广直流输电系统,有了较大的优化与改进,交流滤波器的投切控制主要通过采用冗余配置的SIMATICS5直流站控系统无功控制功能块来实现。采用三调谐交流滤波器,优化了交流滤波器额定电压,采用了合闸角装置进行交流滤波器的投切,这些优化了交流滤波器的结构和选型,改进了投切方式。其定无功功率控制功能也进行了优化,并增加了CSD控制功能,为其日后的安稳运行奠定了基础。Compared to Tian-Guang DC transmission system, the reactive control of Gui-Guang double circuit DC transmission system has been largely optimized and improved. And the connection control of AC filter is mainly realized through the reactive control module of the redundant SIMATIC S5 DC station control system. Triple-tuned AC filter is used to optimize AC filter rated voltage. The structure and type selection optimization, as well as connection method improvement, are realized through closing device. The reactive power control function has also been optimized, and the CSD function has also been added, providing basis for future stable operation.
