| 摘 要： | 随着风力发电的快速发展,如何连接风电场和电网成为至关重要的问题.研究了基于双馈感应电机(DFIG)的风电场连接方式及控制策略,通过与交流输电和电流源型高压直流输电(CSC-HVDC)的比较,说明电压源型高压直流输电(VSC-HVDC)技术在连接风电场与电网方面具有独特优势.在换流站的dq解耦控制基础上,对DFIG与VSC-HVDC的换流站的控制设计进行了研究.利用PSCAD/EMTDC平台对该方案进行了仿真研究.仿真结果表明,该方案可以实现一个换流站连接多台DFIG的结构,并具有良好的控制效果.

| Abstract: | With the fast development of wind power generation,how to connect wind farms to power grids becomes a crucial problem.This paper studies the connection methods and the control strategy of wind farms using DFIG wind turbines. Compared to AC and current source converter based HVDC(CSC-HVDC)transmission,VSC-HVDC transmission technology has its unique advantages in connecting wind farms to the grids.Based on the d-q decoupling control method,the control scheme of DFIG and VSC-HVDC converter is studied.In order to verify the feasibility of the control scheme,simulations are carried on the platform of PSCAD/EMTDC.The results show the validity of proposed connection method and control strategy. |
