为满足我国特高压直流输电发展和建设的需要,提出了满足±1 100kV特高压工程换流阀运行试验系统的设计。根据±1 100kV特高压工程规范,提出了预期运行试验参数,从运行试验系统的一次电气原理设计、二次控制保护设计和测量监测设计3个方面进行讨论和研究,最终通过仿真手段对电气原理和控制系统原理进行了验证。研究结果表明,±1 100kV特高压工程换流阀运行试验系统设计是可行的,可以满足所有运行试验的要求,更加符合换流阀设计的特点,能够达到试验检测目的。该试验回路建成,可以满足±1 100kV工程阀15级串联同时进行运行试验,也将成为世界上容量最大的运行试验回路,可以为我国±1 100kV直流输电工程研发和工程建设提供保障。

To improve HVDC technology that can reduce transmission power loss,to improve capacity of transmission power,and to increase transmission distances,we proposed a new synthetic operational test circuit for ±1 100 kV thyristor valve,and put forward prospective ±1 100 kV UHVDC operational test parameters reference specification.Moreover,we discussed and verified test electrical circuit design,control and protection design and measurement monitoring systems design by simulation tools.The simulation results show that operational test circuit designs are correct and can better meet tests requirements.The test circuit can be used to test a thyristor valve section with 15 thyristor levels series,and the maximum capacity thyristor valve operational test circuit can be used as a platform for HVDC research,development and projects construction.
