单/双协同模式下配电网故障排查的最优巡线规划

Theoretical Optimal Models for Fault Line Inspection in Distribution Network via Single/Dual Cooperative Modes

针对有效制定科学、高效的配电网故障巡线排查方案,提出了一种单/双协同模式下故障排查巡线规划理论最优模型。结合配电网呈辐射状运行的特点,首先,设计了单模式配电网故障排查的最优巡线模型,并分析其计算复杂度;其次,为契合现场作业特点,在单模式模型的基础上衍生构建了双协同模式下高效协同的配电网巡线排查模型,该模型可同时兼顾总排查任务量最小和队间分配任务量更均衡。随后在论述两种模型差异的基础上,通过结合Dijkstra和深度优先搜索算法设计了所提两种模型的求解思路及解决方案。最后,以IEEE 33-Bus和某实际系统为例,验证了所提巡线排查模型的准确性、高效性。

To effectively formulate a scientific and efficient fault line inspection plan,two theoretical optimal models for fault line inspection schemes in distribution network via single/dual cooperative modes are proposed.In combination with the characteristics of radial operation of distribution network,the optimal line inspection model for single-mode fault detection is firstly designed,and then its computation complexity is analyzed.Subsequently,to meet the properties of field operation,a single-mode model based efficient collaborative line inspection model in dual mode is derived.This model can both take the minimum total line inspection length and a more balanced task allocation among teams into account.Finally,solution differences and their processes via Dijkstra and depth-first search algorithm(DFS)between two models are discussed in detail,and taking the system of IEEE 33-Bus and an actual system for example,the accuracy and efficiency of the proposed line inspection models are verified.
