摘要
随着大型风电场的不断投入,其并网暂态稳定问题,也受到人们的关注。基于Dig SILENT仿真平台,分别建立了含有双馈和永磁同步直驱两种不同风力发电机组的电网仿真计算模型。结合某风电场的接入实例,模拟了A市电网发生N-1三相短路故障时,两种不同风力发电机组的暂态稳定情况,并对仿真结果进行了分析比较,给出了参考建议。
With the continuous integration of large - scale wind farms with the grid, the transient stability problem caused by grid connection is attracted more and more attention. Based on Dig SILENT, the simulation model of power grid is established containing two kinds of different wind power generation units, that is, double - fed and permanent magnet direct drive. Ac- cording to an integration example of a wind farm, the transient stability of these two kinds of wind power generation units is simulated during N - 1 three - phase short - circuit fault. The simulation results are analyzed and compared, and the reference suggestions are given.
