| 摘 要： | 为避免高压直流受端换流站逆变器换相失败的问题，同时提高受端换流站交流系统的电压稳定性，将受端换流站改造成柔性直流换流站，形成送端常规直流受端柔性直流的混合直流输电系统。结合南方电网贵广I直流输电工程，为减少改造过程中的停电时间，对两端换流站改造的过渡方案进行深入研究，并提出了常规直流柔性化改造过渡方案，该研究成果对混合直流输电工程有借鉴和参考价值。

| Abstract: | In order to avoid the commutation failures of receiving end convertor Converter station in LCC-HVDC transmission systems, and to improve the voltage stability of receiving end converter station AC system, the Line Commutated Converter in receiving end converter station retrofit for Voltage Source Converter, that form the Hybrid HVDC transmission systems which sending end is LCC-HVDC and receiving end is VSC-HVDC. In order to reduce the outage time during the retrofitting process, intensive study on transition scheme of sending and receiving ends converter station according to Guizhou-Guangdong I HVDC Project of CSG, Put forward transition scheme of LCC-HVDC retrofit for VSC-HVDC, the research results have great reference value to the Hybrid HVDC transmission systems. |
