摘要
比较海上风电场的并网方法,说明了轻型直流输电技术在连接风电场与电网方面具有的独特优势。在换流站的d-q解耦控制基础上,研究设计了轻型直流输电控制器,并利用PSCAD/EMTDC仿真软件,对海上风电场的轻型直流输电模型进行仿真。仿真结果表明,轻型直流输电能很好地承担海上风电场的并网工作,并且具有快速的电流响应特性和鲁棒性。
The grid access methods were compared with each other in offshore wind farm.It illustrated that the VSC-HVDC technology in grid to wind farm had a unique advantage.Based on the dq decoupling control in the converter station,the VSC-HVDC controller was researched and designed,and the VSC-HVDC model of the offshore wind farm were simulated by the software PSCAD/EMTDC.The simulation results showed that the VSC-HVDC could take the post of the offshore wind farm grid access and it had a fast current responsiveness and robustness.
