光纤网络是电力通信的主要承载网络，为保证其高可靠运行，运维人员需要定期进入变电站站点对网络中的光缆纤芯进行检测。然而，变电站数量众多且位置分散，这对光缆纤芯检测带来了巨大挑战。为此，文章针对电力通信光纤网络的多周期光缆检测问题展开了研究，以最小化总入站站点数量为目标，构建了一个整数线性规划模型，并提出了相应的启发式算法。研究结果表明，提出的启发式算法能有效降低运维人员进入变电站的次数。

The optical network has become the most important way to carry power communications. To ensure its high reliability, operators need to detect the cables of the network periodically, which need to enter the substations. However, the large number and scattered location of substations bring challenges to the optical cable detection for the power communication optical network. This paper studies such multi-period optical cable detection problem of optical network in the context of power communication. With the objective of minimizing the total number of entered substations, we developed an Integer Linear Programming (ILP) model and a corresponding heuristic algorithm is also proposed. The simulation results show that the proposed heuristic algorithm can effectively reduce the total number of entered substations and perform close to the results of ILP model.
