| 摘要: |
| 中枢母线选择的最大难点在于确定某个区域内合理的中枢母线数量。引入多元统计分析理论中的主成分分析和因子分析方法，将无功电压灵敏度矩阵作为样本矩阵，提出基于其相关矩阵特征值的累计贡献率准则来决定中枢母线数量，并利用因子载荷阵的数值分布特性确定中枢母线选址。仿真结果表明，利用所提方法选取的中枢母线在自动电压控制中使负荷增长引起的电压跌落减少约44 %。 |

| Abstract: |
| The difficulty in the pilot bus selection is to determine its reasonable amount for each control zone. The principal component analysis and factor analysis method in the multivariate statistics theory are introduced to it，which takes the reactive voltage sensitivity matrix as the sample matrix，determines the amount of pilot bus according to the accumulative eigenvalue contribution rate of its correlation matrix，and selects the pilot buses according to the numerical distribution characteristics of factor loading matrix. Simulative result shows that，the pilot buses thus selected can reduce about 44 percent of the voltage sags caused by load raise in automatic voltage control. |
