摘要
在分析了用于海上风电场的高压交流输电技术、基于晶闸管相控换流器的传统高压直流输电技术和基于电压源变频器的轻型高压直流输电技术等电能输送及其并网方式的特点,并从经济性和技术性上对其进行比较,指出了经济选择范围。对海上风电场内部集电线路的不同布局方式特点及经济性进行了分析,给出了目前最优的经济选择。
Analysis was made to high-voltage AC （HVAC） power transmission technology, traditional high-voltage DC （HVDC） power transmission technology based on phase control converter （PCC）, light HVDC power transmission technology based on voltage source converter （VSC） for offshore wind farm, and characteristics of their grid-connected modes were also discussed. This paper compared these technologies according to their economical efficiency and technicality, pointing out the economic selection range. Analysis was made to characteristics of different topologies of interior current collection line for offshore wind farm and their eco- nomical efficiency, and the economic selection inferior to none at present was given.
