摘　　要：针对吉林省电网的实际运行状况,利用德国开发的电力系统综合分析软件D IgS ILENT/Pow erF actory,搭建吉林省电网及各风电场模型,通过仿真计算,分析了风电场集中接入对地区电网电压稳定性的影响。结果表明,风电集中接入会造成电网中部分节点电压波动,必须进行无功补偿;风电场送出线路发生三相短路故障后,保护装置动作,迅速切除故障线路使系统电压保持暂态稳定。Based on the practical operation situation, models of Jilin Provincial power grid and wind farms have been established by German developed electric power system comprehensive analysis software DIgSILENT/ PowerFactory. Wind farm concentrated integration on area grid stability has been systematically investigated by simulative calculation. The results show that concentrated integration will cause voltage fluctuation on some of the nodes so reactive compensation must be performed~. Protection devices will response when wind farm send out the 3-phrase short circuit , cutting off the fault location to keep transient stability of system voltage.
