摘要:
      由于电网故障或设备检修造成负荷失电,为失电负荷寻找供电路径成为目前许多电网分析软件的必备功能。通过拓扑分析程序将电网划分为若干电气岛,传统的根据树搜索法的孤岛恢复供电路径搜索算法,在路径的搜索上存在不足。文中受因特网路由选择协议算法的启发,将各类电气岛看成路由器,提出一种基于距离向量的搜索算法,通过对各电气岛初始路由表的形成和对路由表的更新处理,最终获得电气岛的全网路由表,通过该路由表可以得到所有可能并且符合调度规程的失电孤岛供电路径。利用内点法最优潮流对搜索得到的供电方案进行可行性验证。以IEEE 14节点标准测试系统为例,验证了该算法的可行性。
Abstract:
      For the load power loss due to power grid failure or equipment maintenance, it has now become an essential function of looking for a power supply path for the power lost load in a lot of power grid analysis software. The grid can be divided into several electric islands through the topological analysis program. The traditional searching algorithm for island restoration of power supply path based on the tree search method is inadequate in path searching. Inspired by the Internet routing protocol algorithm, all kinds of electric islands are regarded as routers while a kind of search algorithm based on distance vector is put forward. Through the formation of initial routing tables and routing table update processing, the entire network routing table of each island is eventually obtained, through which all the possible power supply paths of power losing electric islands in conformity with dispatching schedules can be obtained. By using the optimal power flow of the interior point method, the feasibility of power solutions is verified as is the algorithm effectiveness on an IEEE 14-bus standard test system.
