摘 要：设计了一种背靠背型的晶闸管阀运行试验回路，该回路既可以作为晶闸管阀电流试验平台使用，也可以作为无功补偿设备( 如SVC、SVG) 的长时间运行试验平台。该回路的设计参照高压直流输电(HVDC) 中背靠背(BTB) 直流系统的参数计算，实现大直流电流运行，并且将有功能量返回，使整套系统的能耗大大降低。经仿真分析验证了设计参数的正确性，为晶闸管阀的合成试验回路奠定了基础。

Abstract: This paper designed a back-to-back (BTB) operational test circuit for high-voltage thyristor valves, which could be used as the current test platform for thyristor valves, but also be used as the long-turn operational test platform of reactive power compensation equipment, such as SVC, SVG. With the reference to the BTB DC system of HVDC transmission parameter, the circuit was designed to realize large DC current operation and returned the active power, so that the energy consumption of the entire system is greatly reduced. The computer simulation was carried out to verify the correctness of the design parameters, so as to lay the foundation for synthetic test circuit of thyristor valves.
Key words: thyristor valve; reactive power compensation equipment; back-to-back; operational test
