摘要:
      对大型风电场接入后的电力系统暂态稳定性进行了研究。从理论上分析了基于双馈感应电机的风电机组的暂态稳定机理;基于双馈风电机组的动态数学模型,通过仿真计算研究了大型风电场并网对电力系统暂态稳定性的影响,分析比较了在同一接入点接入双馈风电机组与接入同步发电机组对电力系统稳定性的影响,仿真计算进一步验证了理论分析的结果;最后得出结论:基于双馈风电机组的风电场对电力系统暂态稳定性的影响要好于在同一接入点接入相同容量的同步发电机组。
Abstract:
      Impact of large scale wind farm integration on power system transient stability is studied in this paper. The transient stability mechanism of wind turbines based on doubly-fed induction generator (DFIG) is analyzed theoretically. Then the dynamic model of wind turbines based on DFIG is used to study the impact of wind power integration on the transient stability of the grid, and the comparison of different impacts on the grid transient stability is conducted between the wind turbines based on DFIG and the substituted synchronous generator with same capacity in the same connection point. The digital simulations verify the theoretical analysis. It is concluded in the paper that the wind farm integration based on DFIG into the power system is better than that of synchronous generation units at a same point in the power system as far as system transient stability is concerned.
