分析了海上风电桩基腐蚀、牺牲阳极和外加电流阴极保护的原理,对比了两种阴极保护的优缺点,重点阐述了外加电流阴极保护系统在某电场桩基上的应用,包括设计、安装和调试。外加电流阴极保护技术因其自动、远控的特点,在我国海上风电具有广阔的应用前景; 而其真正推广,还有赖于运行管理经验和成功案例的积累。

The principles of corrosion and sacrificial anode and impressed current cathodic protection of offshore wind pile foundation are analyzed. The advantages and disadvantages of those two cathodic protection ways are compared, and the studies and applications including design, installation and debugging of the impressed current cathodic protection system in an offshore wind farm are expourded. The impressed current cathodic protection technology has broad application prospects in domestic offshore wind farms because of its characteristics of automatic and remote control; and its real promotion also depends on the accumulation of experience and successful cases of operation and management.
