最新的基于电压源换流器(VSC-HVDC)的高压直流输电可以独立控制有功和无功,有功无功可四象限运行,进而直流线路的两端系统可以独立运行,故具备黑启动能力。 8.电磁场 就磁场而言,HVDC架空线与HVAC架空线相当。对于1-1.5 kA的额定电流,架空线路最高的磁通密度在20和25μT在之间。磁通密度在距离高压直流输电线路40米...
同时,高压直流(hvdc)被证明是解决可再生能源整合问题的一个较好的解决方案。截至目前,已有两种成熟的hvdc技术可供选择:lcc-hvdc(基于电流源换流站的高压直流输电)和vsc-hvdc(基于电压源换流站的高压直流输电)。为了充分发挥各自的优势,lcc和vsc相结合的混合交直流系统受到了越来越多的关注。更重要的是,最近的研究表明...

Large-scale offshore wind power has been developed in recent years, and two possibilities are considered for the transmission system between the offshore wind farms and the onshore grid: VSC-HVDC and HVAC. The paper aims to compare both systems for 300MW offshore wind farms, 25 km, 50km ...
Phase 2 of the project will see a western extension of the HVDC line from Barkeryd to Tveiten in Norway to create a multi-terminal DC system. The design of the Barkeryd station allows for the future connection of underground cables, with minimal disruption to the operation of Phase 1. As...
? 2023 Elsevier B.V.New grid elements such as Voltage Source Converters (VSC) and cables are being increasingly used in today's power grid. These new grid elements behave differently compared to synchronous machines and overhead lines during transients and faults, impacting the present system's ...
