开年即加速，起步即冲刺。全国首个海上风电海陆一体柔性直流输电工程——阳江三山岛海上风电柔直 输电工程（以下简称"三山岛工程"）建设按下"加速键"，目前整体进度已近半，今年3月海上换流站导 管架赴阳江海域安装的筹备工作紧锣密鼓，7月海上换流站陆上建造部分启运也进入倒计时。 三山岛不是岛。它是距离广东阳江海岸100多公里的深远海域。未来那里的风机发出的电都将通过三山 岛工程送至粤港澳大湾区。 区别于以往海上风电送出模式，三山岛工程由广东电网公司统一规划和建设，阳江三山岛海上风电一至 四项目可实现"一站式拼车"。 三山岛工程也是我国首个海上风电海陆一体柔性直流输电工程。三山岛工程分海陆两部分，海上工程包 括一座±500千伏海上换流站、辅助平台及115公里的500千伏直流海缆。陆上工程包括阳江海岸的海缆 转架空终端站、江门古劳换流站以及途经阳江、江门、佛山的近200公里架空线。工程计划于2026年10 月投产。 自2025年4月全面开工以来，三山岛工程建设整体进度已近半。目前海上换流站在振华重工南通生产基 地陆上建造，预计今年7月初启运。在此之前，海上换流站的"腿"——导管架预计今年3月先期抵至阳江 海域安装。陆上换 ...
