基于VSC-HVDC并网的大规模海上风电场将是未来电力系统的重要电源之一。随着其规模的不断扩大，传统小规模交流并网风电场的运行控制和保护方法不再适用。因此，面向大规模海上风电场的分布式控制与保护技术亟待研究。据此，本项目将开展以下工作：研究基于分布式一致性和分布式优化的风电场有功控制方法，聚焦于分布式算法框架及模型预测控制的应用；研究基于分布式优化的风电场无功/电压控制方法，聚焦于非线性潮流约束的处理及分布式优化框架的设计；研究海上风电场系统的故障特征分析，聚焦于永磁同步全功率型风电机组的故障特征及整个集电系统的故障分析方法；研究海上风电场集电系统的保护原理与配合机制，包括传统保护适应性分析、新保护原理研究、保护配置方案及多重保护间的协调与配合。.本研究旨在建立适用于大规模海上风电场的分布式运行控制体系和保护系统，解决关键理论与技术问题，为进一步推动海上风能的大规模应用奠定技术基础。

VSC-HVDC-connected large-scale offshore wind farms will become one of the important power sources in the future. As the scale of wind farms rapidly grows, the conventional control and protection techniques adopted in small-scale AC connected wind farms are no longer suitable. Consequently, the corresponding distributed control and protection techniques for large-scale offshore wind farm are urgently needed. Targeting this research area, this project will cover the following research work: research on distributed consensus and optimization-based active power control of wind farms with the focus on the distributed algorithm framework and application of model predictive control; research on the distributed optimization-based Var/Volt control scheme with the focus on the nonlinear power flow constraints and design of distributed optimization framework; research on fault characteristics analysis of offshore wind farms with the focus on fault characteristics of PMSG full-converter wind turbines and fault analysis method of the entire wind farm collecting system; research on protection principle and corresponding coordination mechanism, including adaptability analysis of conventional protection principles, new protection principles, protection configuration scheme and coordination mechanism of multiple protection involved in wind farm collecting system..This project aims to develop the distributed operation control architecture and protection system of large-scale offshore wind farms, tackle with the corresponding key theoretical and technical issues as well as lay the technical foundation of large-scale exploitation of offshore wind energy.
