摘要
葛(洲坝)—南(桥)直流输电系统是首次由我国自主完成控制保护系统改造的±500 kV长距离、大容量和超高压直流输电工程。统计了葛南直流输电系统2006年的主要运行指标,分析了运行中发生的原因较为复杂且具有代表性的多项事件,并提出相应的对策和建议。这些经验同样适用于其他高压直流输电系统,有助于提升我国高压直流输电工程的设计、调试和运行水平。
±500 kV HVDC power transmission project from Gezhouba to Nanqiao is the first long-distance, large-capacity and high-voltage HVDC project whose control ＆ protection system had been retrofitted solely by the domestic technical force. In this paper the statistics of main operational indices of ±500 kV Gezhouba-Nanqiao HVDC power transmission system in the year of 2006 are presented. The representative accidents triggered off by complex causes during its operation are analyzed, and corresponding countermeasures and suggestions are proposed. These operation experiences are suitable to other HVDC power transmission systems as well and contribute to further improve the design, commissioning and operation level of HVDC power transmission projects in China.
