摘要
对应用比较广泛的电压控制区域(VCA)划分方法进行了改进,在传统的去除小元素法基础上,采用牛顿—拉夫逊法潮流雅可比矩阵中有功和无功对电压幅值偏导数的子矩阵之和进行VCA划分;然后,将各种拓扑变化对系统电压稳定性的影响进行排序,按从大到小的顺序用这些拓扑变化对得到的VCA分区进行修正,直到修正结果不再改变为止,从而得到了适用于各种拓扑结构下电压稳定性分析的分区。改进后分区的有效性在新英格兰10机39节点系统上得到了验证。
An improvement is made to the widely used area partitioning method of voltage control areas （VCA）. Based on the traditional area partitioning method by eliminating small elements, a new idea to get VCA is adopted, using the sum of the PV and QV parts of the Jacobian matrix in Newton Raphson load flow. Then all the different topology changes are ordered according to their effect to the system voltage stability and are used to revise those VCA, from the topology change which has the largest effect to the one that has the least effect, until the partitioning result doesn＇t change. Thus the final VCA could be applied for the analysis of voltage stability in systems of any network topology. The improved method has been evaluated and validated on the 10-generator, 39-bus New England Test System.
