| 摘 要： | 针对负荷波动情况，分析3种常见风电机组的结构特点;利用MATLAB的电力系统分析工具箱PSAT建立了含风电场的14节点算例系统，通过时域仿真研究了相同节点接入不同风电机组对电力系统电压稳定性的影响，对3种机组及其系统的暂态电压稳定性进行了分析对比;讨论了负荷增长方式的不同、风机接入方式的不同对风电并网点电压稳定性的影响。结果表明:负荷增长倍数越大、负荷同时增长、风机分散接入加剧了系统电压的不稳定。

| Abstract: | In view of the load fluctuation, the structural characteristics of three common wind turbines were analyzed. The MATLAB power system analysis toolbox PSAT was used to establish a 14|node example system with wind farms was studied by Time domain simulation was used to study the effects of different wind turbines connected to the same node on the voltage stability of the power system. The transient voltage stability of the three units and their systems was analyzed and compared. Finally, the effects of different load growth modes and different fan access modes on the voltage stability of wind power grid|connected points were discussed. Results show that the larger the load growth multiple, the one|time increase of the load and the decentralized access of the fan, the greater instability of the system voltage. |
