随着近几年智能电网的建设, 电力通信网作为服务于电力行业的专用网, 已成为电力系统的重要组成部分, 其可靠性对电力系统的正常生产起到十分重要作用。文章提出了一种模糊层次分析法, 采用模糊一致矩阵为各组成因素对电力通信网的安全可靠性影响作定量分析, 该方法很大程度上提高了评价的科学性。通过计算发现, 电源系统故障时间、双通道化率、节点成环率和光缆中断时间等因素对电力通信网可靠性的影响权重较大。

With the construction of smart grid in recent years, as a service in the electric power industry, the power communication network has become important components in the system. Its reliability plays an important role in the normal production of electric power system.This paper presents a fuzzy analytic hierarchy process, which uses the fuzzy consistent matrix to quantitatively analyze the influence of each component on the reliability of power communication network.This approach greatly improves the scientific evaluation.By analyzing the calculation results, it is found that the failure time of power supply system, the rate of double channelization, the ring formation rate and the cable interruption time have great influences on the reliability of power communication networks.
