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。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.
