| 摘 要： | 以往的动态无功配置方法大多以确保静态电压稳定为目标，而快速可控的动态无功补偿装置更适用于抑制电网的暂态电压失稳。文中首先分析并指出故障后的极限切除时间是系统暂态电压稳定性的一个衡量指标，安装动态无功补偿可以延长故障的极限切除时间。根据这种特点提出了一种基于极限切除时间指标的动态无功优化配置算法，比较各种配置方案对电网故障后极限切除时间的改变量以得到最优方案。通过IEEE 39母线系统的算例说明了该方法的有效性。

| Abstract: | The available allocation methods of dynamic Var compensation almost take the ensuring static voltage stability as the objective,while fast responsibility makes dynamic Var compensation suitable for maintain transient voltage stability.In this paper,the mechanism of transient voltage collapse and improving transient voltage stability by dynamic Var compensation are analyzed.It is concluded that the critical fault clearing time can be used as an index to evaluate the transient voltage stability,and the alloca... |
