摘要
锡盟-泰州直流输电工程是世界上首个将±800 kV直流输电容量由8 000 MW提升到10 000 MW,额定电流提升至6 250 A直流输电工程。介绍了该工程泰州站6 250 A换流阀组件主要技术参数,并重点介绍6 250 A换流阀电抗器通流的优化设计,阻尼回路优化设计,光纤冗余触发系统优化设计,组件水路优化设计。优化后的±800 kV/6 250 A换流阀通过型式试验,满足工程应用要求。
Ximeng-Taizhou HVDC project is the first worldwide DC power transmission project whose maximum rated current and power is up to 6 250 A and 10 000 MW. The main technical parameters of the converter valve is explainses. The optimization design of converter valve reactor for raising electric current, optimization design of damping circuit, optimization design of optical fiber redundancy triggering system and optimization design of component waterway are mainly introduced.Optimized±800 kV/6 250 A converter valve has passed the type test and can satisfy the engineering requirements.
