摘要
采用交、直流站合建的方案,把一般情况下分开建设的直流换流站和交流变电站"捆绑"建设在一个站内,可以减少公共资源、节约占地、节省投资。基于国内现有±500kV换流站以及正在建设的特高压直流输电工程,总结归纳交直流合建高压换流站的特点,就系统方案、电气主接线、总平面布置、站用电系统等主要技术原则,分析高压换流站交、直流合建中应注意把握的主要技术内容,为换流站的交直流合建提供参考。
The combined AC and DC converter station construction scheme that ties DC and AC converter stations built separately under normal conditions into a single station, can conserve public resource, reduce land occupation, and lower costs. Based on existing domestic -＋500 kV converter station and under-constructing UHV DC transmission projects, the characteristics of combined HV AC and DC converter station construction are summarized. Main technical principles, including system plan, bus configuration, general layout, and auxiliary power system, etc., are also concluded. Major technical contents that should not be ignored during construction are analyzed.
