摘　　要：电力通信网络易受背景噪声干扰、磁场干扰等因素影响,导致电力通信网链路发生故障。为保证电力系统安全稳定地运行,提出一种基于波分复用的电力通信网链路故障保护算法。通过电力通信网链路模型计算链路可靠度,分析网络运行状态;通过波分复用技术重新分配路由和波长容量,构建链路生存模型,设定故障保护目标优化函数和相应的约束条件,根据冗余释放理论,对电力通信网容量实施保护措施,降低光链路中的波长信道需求,实现链路故障保护。实验证明,所提算法能快速寻找到多条链路故障保护条件,经过确认权重并能重新分配路由,可实现链路故障的高效保护。通过对比实验可以看出,所提算法的保护冗余度低,不影响网络正常运行,能节约电力通信网络资源。In order to eliminate the influence of background noise,magnetic field and other factors and ensure the safe and stable operation of power system,a link fault protection algorithm of power communication network based on wavelength division multiplexing was proposed.The link reliability was calculated by the link model of power communication network,and the network operation state was analyzed.Through the wavelength division multiplexing technology,the routing and wavelength capacity were redistributed,the link survival model was constructed,the fault protection objective optimization function and the corresponding constraint conditions were set,and the capacity of the power communication network was protected according to the redundancy release theory so as to reduce the wavelength channel demand in the optical link and realize link fault protection.The proposed algorithm can quickly find multiple link fault protection conditions,and redistribute routes after confirming weights,so as to achieve efficient protection of link faults.The experimental results show that the proposed algorithm has low protection redundancy,does not affect the normal operation of the network,and can save power communication network resources.
