| 摘要: |
| 研究了带分散风机控制和直流输电的海上风电场并网控制,利用基于功率控制的方法对HVDC Light系统并网控制进行了仿真,实现了双侧独立控制,风机侧由多台分散风机各自带换流器组成,通过并联多台风机从而提高系统传输容量和可靠性,风机侧换流器分别采用基于滞环比较的功率控制算法,而系统侧换流器采用基于虚拟磁链的直接功率控制.仿真结果证实了基于该算法的HVDC Light系统连接大型海上风电场可以正常稳定地运行,多台换流器对有功功率和无功功率分别进行协调控制,并且可以满足系统不同的无功需求,而当风速变化时,风机侧可平滑调整输出功率的大小,并无损耗稳定地输送到系统侧. |

| Abstract: |
| The HVDC grid connection control of offshore wind farm with dispersed wind turbine control is studied.The HVDC Light simulation system is built based on power control,implementing the independent control at both sides.There are dispersed wind generators with respective converter in parallel to improve transmission capacity and reliability.The converter at wind turbine side adopts the power control method based on hysteresis comparison,while that at system side adopts the virtual flux direct power control.Si... |
