我国直流输电技术自主创新研究

直流输电工程在我国“西电东送”中发挥了巨大作用。但目前投运的直流输电系统几乎全部由外商成套供货,整个系统的设计、制造、试验、安装、调试等核心技术仍由外方主导。随着直流输电容量在西电东送中占据越来越大的份额,直流输电工程自主化迫在眉睫。针对我国在直流输电工程自主化中存在的主要问题,介绍了南方电网技术研究中心在高压和特高压直流输电工程技术自主创新实践中的主要工作和体会,对我国特高压直流输电关键设备自主研发提出一些看法和建议。

Research on self-reliance innovation in HVDC power transmission technologies

HVDC power transmission projects take the key role in transmitting electric power from the west area to the east in China.However,the main equipments of the existing HVDC projects were provided in set by foreign providers,and the core technologies of set design,manufacturing,installation,and commissioning were dominated by the foreign providers.With the capacity of HVDC power transmission taking more and more quotient in power transferring from the west area to the east in China,the self-reliance progress of the HVDC power transmission technologies becomes instancy.Aiming at the main issues of self-reliance progress of the HVDC power transmission technologies,the paper introduced the self-reliance innovation in the HVDC and UHVDC technologies conducted by CSG Technology Research Center.Some proposals on self-reliance research and development of UHVDC equipment are brought forward.
