大电网局部区域整定计算时，采用全网模型耗时过长，如何快速缩小计算时的电网规模成为重要的研究课题。根据复杂网络理论，形成带权电力网络。配合区域和约束区域构成了整定计算缓冲网。确定整定计算范围后，根据一级远后备保护使用方法，确定边界支路相邻支路及末端节点为配合区域。利用最短电气路径确定边界支路、配合支路的最小环网结构，利用边界节点自阻抗变化率确定厂站范围。最小环网结构和厂站范围组成了约束区域。最后通过深度搜索/回溯技术实现了缓冲网的自动生成。

It is time consuming to use the entire network to conduct setting calculation for local area. The way to narrow down the grid size for setting calculation becomes an important subject. Based on the complex network theory, the weighted power network model is formed. The buffer subsystem for setting calculation consists of the coordination region and constraint region. After determining the scope of setting calculation, we include the adjacent branches of boundaries and its end nodes in the coordination region according to remote backup protection. Furthermore, the shortest electrical path is used to determine the minimum ring network of boundaries and coordination branches. Meanwhile the substation scope is determined by the self-impedance variation rate of boundary nodes. The constraint region consists of the smallest ring structures and substation scope. Under these, the depth first search and backtracking technique are applied to form the buffer subsystem automatically.
