大规模风电联络线重合闸方式研究

Auto-reclosing Strategy for Large-scale Wind Farm Transmission Line

对当前大规模风电送出线路所采用的重合闸方式进行仿真分析,指出其不适应于风电场集中式接入的原因,提出根据不同风电场送出系统结构采用不同的重合闸策略,以适应当前风电接入现状。经仿真验证该策略能够切实增强风场联络线路在故障期间的功率送出能力,并对保证风场母线上负荷持续供电及系统的安全稳定运行有显著效果。

Based on the simulation analysis of the reclosing mode of large-scale wind farm transmission system at present, the reason for its inadaptation to the centralized access of wind farm is pointed out, and adopting different reclosing strategies according to different wind power delivery system structure is proposed, so as to adapt to the current situation of wind power integration. Simulation verifies that this strategy can enhance the power delivery capacity of wind farm transmission line during the fault period, and has significant effect on ensuring safe and stable operation of the power system.
