摘　　要：提高定位装置利用率缩减成本是广域行波测距研究的重点之一。行波传输路径与故障位置有关,文中将网络中的所有线路预设为故障支路,并考虑故障位置分别为线路两端部分的严重情况,将复杂网络简化为不含环路的网络,进而分析初始波头的传输路径,从而求取公共配置集。考虑了线路退出运行的情况,基于配置集合建立约束条件,利用基于模拟退火的粒子群优化算法求取最优配置方案。该方案能够保证系统中任意位置出现故障均能够被观测,同时结合D型行波法和组合测距算法,有效降低广域测距定位单元配置数目。仿真结果证明了配置方案可行性。Increasing the utilization ratio of the location device and reducing the cost is one of the keys to research in wide area traveling wave location.In fact,the traveling wave transmission path is related to the fault location.All the lines in the network are set to fault branch in advance,and the serious conditions of the fault location at both ends of the line are considered.Then,the complicated network is simplified to a network without loops.And the transmission path of the initial wave head is analyzed to obtain the common configuration set.At the same time,the condition in which the line exits operation is considered.The constraint condition based on the configuration set is established,and the optimal configuration scheme using the particle swarm optimization algorithm based on the simulated annealing is obtained.The scheme can guarantee that any fault in the system can be observed.Meanwhile,by combining the D-type traveling wave algorithm and combined location algorithm,the number of wide-area location units is effectively reduced.The simulation results show the feasibility of the configuration scheme.
