柔性直流输电技术是比传统直流输电更先进的直流输电技术。所以除了拥有传统高压直流输电技术即可以控制有功功率又可以控制无功功率、输电距离基本不受限制、直流输电比交流输电更稳定、实现异步系统互联和减轻环境影响的优点，柔性直流输电还具备许多自身特有的优点。(Flexible HVDC transmission technology is more advanced than traditional HVDC transmission technology. Therefore, in addition to the advantages of traditional HVDC technology, such as active power control and reactive power control, almost unlimited transmission distance, more stable HVDC than ac transmission, asynchronous system interconnection and environmental impact reduction, flexible HVDC also has many unique advantages.)
