摘　　要：以708和538节点系统为算例,对以非线性原对偶内点法为基础,基于近似牛顿方向和对角加边模型的5种无功优化分解协调算法的计算效益和收敛性进行了比较分析。并进一步分析了影响分解协调算法计算效益和收敛性的因素。定性分析了固定系统总规模、扩大子区域数目和固定子区域数目、扩大最大子区域的规模2种方式对计算速度的影响。Taking 708-bus power system and 538-bus power system for calculation examples, the comparative analysis on computation efficiencies and convergence of five reactive power decomposition and coordination algorithms which are based on nonlinear prime-dual interior point method, approximate Newton directions and block bordered diagonal frame model respectively are performed. Then the factors influencing the computation efficiencies and convergence of decomposition and coordination algorithm are further analyzed. The influences of two kinds of methods, i.e., fixing the general scale of the system and expanding the number of sub-area as well as fixing the number of sub-area and expanding the scale of maximum sub-area, on computing speed are quantitatively analyzed.
