摘要
海上风电由于具有风能稳定、密度大等优点,在世界范围内已逐渐发展成为风力发电的重要形式。在深远海域,风能资源更丰富,风湍流强度与海面粗糙度较近海更小,因此深远海风电发展将成为未来海上风电发展的主要趋势。首先,阐述了海上风电深远海化发展趋势,总结了3种海上风电的并网方式及相应的拓扑结构、主要运行特点。其次,考虑深远海风电的特殊性,重点分析了集电系统可靠性评估与设计、海上升压站设计与换流站设计等3方面的发展趋势。最后,对亟待开展的研究方向、需求进行说明,为深远海风电发展提出建议。
Offshore wind power generation system is now being the major form of wind power generation around the world due to stability and high density of offshore wind pow er.Furthermore, the wind power density is richer as well as wind turbulence and sea surface roughness is smaller in deep water area. Therefore, the development of long distance offshore wind power generation is the main trend of offshore wind power generation. Three main offshore wind integration techniques,topologies and operation characteristics are introduced in this paper. Reliability assessment and design techniques of collection system, offshore AC substation and converter station design techniques are specially discussed with respect of deep water conditions. Finally, the development and research field of offshore wind power generation is described for further study.
