摘  要:首先分析了最常见的永磁同步发电机组和双馈发电机组的数学模型,并构建了一个9MW的风电场接入配电网的仿真模型,在仿真模型上对输电网处和风电场出口处进行了三相短路故障的仿真,在两种短路情况下,对有、无风电场接入时的情况进行了对比分析。仿真结果表明,为确保系统的稳定运行,不能忽略风电场接入对系统产生的影响。Firstly,the mathematic models of the most common permanent magnet synchronous generator units and doubly fed generator units were analyzed,and the simulation model of a 9 MW wind farm connected distribution network was constructed,Based on the simulation model,the simulations of three-phase short circuit faults in the distribution network and at the outlet of wind farm were carried out.Under the two situations of short circuit,the situations with or without wind farm connection were compared and analyzed.The simulation results indicate that in order to ensure the stable operation of the system,the generated influence of wind farm connection on the system could not be neglected.
