摘要
从电力系统潮流分布的角度来看,SVC是一种反馈式的补偿措施,它在电力系统方面的影响可以认为是对相关变量空间的一种拓扑变换,从而等价性地保全电力系统的局部拓扑,因此,如何选择SVC的安装地点就非常重要。通过模态分析方法计算出各负荷母线的母线参与因子,并通过母线参与因子大小确定薄弱母线与薄弱区域,从而确定SVC的最佳安装地点。并将此方法应用于提高南京实际电网的静态电压稳定性,从而为SVC安装地点的选择提供理论基础与应用参考。
From the perspective of power flow distribution, SVC is a kind of feedback compensation measures. Its influence can be deemed as a kind of space topology transform of the relevant varia-bles, thus, equivalently assuring partial topology of power system . Therefore, it is very important on how to select installation location of SVC. The bus participation factor of each load busbar is calculat- ed through modal analysis, the weak busbar and area are determined through magnitude of busbar participation factor, thus determining optimal installation location of SVC. Moreover, this method is used to improve static voltage stability of Nanjing power network, thus providing theoretical basis and application reference on the selecting installation location of SVC.
