摘要
随着海上风力发电的大力发展,海上风机的单机容量和风电场规模也在不断增长,35kV集电系统逐渐不能满足大容量和大规模的海上风电项目。基于目前这种情况,提出66kV集电系统作为海上35kV集电系统的替代方案,通过技术经济性的对比,能够发现相同风电场采用66kV集电系统能够减少场内回路数和路径长度,减少海底电缆敷设工期;66kV集电系统的输电容量和输电距离等输电能力远高于35kV集电系统;通过对比研究发现在大规模海上风电场,66kV集电系统能够节省总投资10%~25%。研究结果可为海上风电场提供参考。
with the rapid development of offshore wind power,the capacity of offshore wind turbines and the scale of wind farms are also increasing,and the 35kV power collection system can not meet the needs of large-scale offshore wind power projects.Based on the present situation,this paper puts forward 66 kv collecting system as an alternative scheme of 35 kv collecting system on the sea,it can be found that the same wind farm with 66 kv collecting system can reduce the number of loop and path length,reduce the submarine cable laying period;The performance of active power loss and cable current carrying capacity of 66 kv collector system is much higher than that of 35 kv collector system.The research results can provide reference for offshore wind farms.
