【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。
[Abstract]:Increasing the utilization rate of positioning equipment and reducing the cost is one of the key points in the research of wide-area traveling wave ranging. The traveling wave transmission path is related to the fault location. In this paper, all the lines in the network are assumed to be fault branches, and considering the serious situation that the fault location is the two ends of the line, the complex network is simplified to a network without loop. Then the transmission path of the initial wave head is analyzed and the common configuration set is obtained. Considering the condition of line exit, the constraint condition is established based on configuration set, and the optimal configuration scheme is obtained by particle swarm optimization algorithm based on simulated annealing. This scheme can ensure that faults can be observed at any position in the system. Combined with D-type traveling wave method and combined ranging algorithm, the number of wide-area location units can be effectively reduced. The simulation results show that the configuration scheme is feasible.
