摘　　要：为解决我国电力通信骨干网资源紧缺问题,该文主要研究可以同时保护变电站通信节点故障和站间光纤链路故障的路径P圈保护方案。依据电力通信网建设规范中提出的以端到端路径长度限制为业务时延约束,在考虑变电站间实际光纤链路容量限制的条件下,基于电力通信网业务典型的汇聚特征,提出等势P圈生成算法,然后建立最优化整数线性规划(integer linear programming,ILP)配置模型,通过优化电力通信骨干网的通信通道配置来提高其资源利用率。以电力通信十三五规划中江苏省某地区的电力通信网拓扑为例进行仿真,并与现有的电力通信网双路由算法以及电信网络中的故障独立路径P圈算法进行对比,从资源利用率、保护路径长度以及最大业务容纳量等多项指标验证了该文所提算法的高效性。此外,业务路由均衡对等势P圈配置的优化也进行了初步研究。In order to solve the shortage of power communication backbone network resource in China, this paper studied a path P-cycle protection scheme that can protect the fault of substation communication node and the fault of fiber link between substations. According to the power communication network construction specification, the end-to-end path length limitation was taken as the service delay constraint, considering the actual fiber link capacity limitation between substations. Based on the typical convergence characteristic of the electric power communication network(EPCN) service, an equipotential P-cycle generation algorithm was proposed and an integer linear programming(ILP)configuration model was established to improve the EPCN resource utilization by optimizing the communication channel configuration of the power communication backbone network.The simulation was conducted in the EPCN topography of an area from Jiangsu province in the 13 th five-year power communication plan for Jiangsu province. Compared with the existing dual-routing algorithm of EPCN and the fault-independent path protection P-cycle algorithm in telecommunication network, this paper analyzed several indexes such as resource utilization, protection path length and the maximum capacity of service to verify the efficiency of the proposed algorithm. In addition, the effect of demand route balance on the optimization of equipotential path P-cycle configuration was also investigated.
