| 摘 要： | 针对电压稳定分析的连续潮流和模态分析方法进行研究,详细推导了连续潮流和模态分析的具体算法.连续潮流通过局部参数化和预测校正的方法克服其在拐点的奇异性,模态分析则给出节点参与因子和支路参与因子用于标识电压稳定性.结合某省网进行实例分析,证明了节点参与因子和P-U曲线在反映电压稳定性上具有一致性.计算结果表明:连续潮流方法可快速、准确求得系统最大负荷点,判断系统稳定裕度;模态分析方法可以很好定位电压稳定的薄弱区域.

| Abstract: | The continuation power flow and modal analysis approach for power system VSA(Voltage Stability Analysis) is presented and the key algorithms are derived.Local parameterization and prediction-correction of continuation power flow approach are used to overcome its singularity at inflexion.Modal analysis provides the participating factors of nodes and lines to identify the voltage stability.Simulative results for a provincial grid indicate that,the nodal participating factors and P-U curves have consistency in... |
