电压源换流器高压直流（VSC HVDC）是一项相对较新的技术，允许连接孤岛电力系统。因此，它可以形成未来大型海上风电场和陆上输电网之间的连接。在本文中，VSC HVDC 解决方案被提议作为高压交流电 (HVAC) 的一种有前景的替代方案。传输技术的选择主要基于经济考虑。因此，本文对VSC高压直流输电的经济价值进行了研究。与 HVAC 相比，VSC HVDC 对于海底安装具有重要的技术优势。目的是在经济比较中将这些优势货币化。考虑了由于使用 VSC HVDC 可能导致的风电场拓扑简化和优化。根据传输电缆的所有权，盈亏平衡电缆长度（选择 HVDC 选项）会有所不同。本文包括敏感性分析。版权所有 © 2009 约翰·威利父子有限公司
Voltage source converter high voltage direct current (VSC HVDC) is a relatively new technology which allows the connection of islanded power systems. As such, it can form a connection between large-scale future offshore wind farms and the onshore transmission grid. In this paper, the VSC HVDC solution is proposed as a promising alternative for high voltage alternating current (HVAC). The choice for a transmission technology is primarily based on economic considerations. Therefore, the economic value of VSC HVDC is investigated in this paper. VSC HVDC has important technical advantages for submarine installation compared to HVAC. The aim is to monetize these advantages in an economic comparison. Possible wind farm topology simplifications and optimizations due to the use of VSC HVDC are taken into account. Depending on the ownership of the transmission cable, the break-even cable length, above which the HVDC option is chosen, varies. A sensitivity analysis is included in this paper.
