摘要:
      为满足电力需求响应(DR)业务对实时、可靠通道的技术需求,解决DR多播业务的通道保护问题,提出了一种面向电力DR业务的P圈保护算法。通过评估DR多播链路的重要度,采用边扩张和对偶圈合并算法对已配置的P圈进行优化,实现对DR重要链路的优先保护。仿真结果表明,所提出的算法有效减少了P圈的数量和保护失效率,提高了保护资源的复用度,能够为电力DR业务的通道级故障的快速恢复提供有力支撑。
Abstract:
      In order to meet the need of demand response(DR)for real-time and reliable communication connections and solve the communication protection problem of the DR multi-cast service in power communication network, a P-cycle protection algorithm for power DR service is proposed. By evaluating the importance of DR multi-cast links, the edge expansion algorithm and the cycle combination algorithm are used to optimize the configured P-cycles, so as to realize preferential protection of DR important links. Simulation results show that the proposed algorithm can effectively reduce the number of P-cycles and the protection failure ratio, and improve the reuse ratio of protection resources, which is able to provide strong support for the fast recovery of communication failure in DR service.
