随着国内外大容量远距离海上风电的开发，采用海陆一体化柔直送出方案具有更大的经济优势。海陆一体协同直流输电技术路线为多端柔直系统，换流站间的协调控制是其研究重点方向之一。首先，在介绍海陆一体化多端柔直送出拓扑的基础上，明确了海陆一体化柔直送出工程各换流站的运行方式和控制模式；其次，提出了多端换流站的控制模式自动切换策略、换流站之间有功功率协调控制策略、直流耗能装置之间的优化控制策略，并设计了启动判据及实施流程。最后，通过搭建的海陆一体化柔直送出仿真平台，充分验证海上风电柔性直流送出系统核心控制策略的正确性。
With the development of large capacity and long-distance offshore wind power both at home and abroad，the use of the offshore-onshore integration VSC HVDC transmission scheme offers greater economic advantages.The offshore-onshore integrated coordinated HVDC transmission technology is multi-terminal VSC HVDC system and the coordiantion and control between converter stations is one of its important research directions. Firstly，based on the introduction of the offshore-onshore integrated transmission topology，the operation and control modes of each converter station in the offshore-onshore integrated VSC HVDC transmission project are clarified. Then，the automatic switching strategy for the control mode of of multi-terminal converter stations，the coordinated control strategy for active power among converter stations， the optimization control strategy for the DC energy storage devices are proposed，and the start-up criteria and implementation process are designed. Finally，the correctness of the core control strategy of the offshore wind power VSC HVDC transmission system is fully verified through the setup of a offshore-onshore integrated VSC-HVDC transmission simulation platform.
