摘　　要：电力需求响应业务近年来快速发展,其传输所依赖的电力通信网的生存性正在逐步得到重视。通过研究网络编码P圈（preconfigured cycle,P-cycle）对于链路的保护方式,结合需求响应业务流特征,提出了面向需求响应的网络编码P圈生成算法（demand-response-oriented network coding P-cycle,DR-NCPC）。首先,分析DR业务流向和可靠性的特殊性,其次结合DR业务的特点对备选P圈集合进行扩张,从而实现对DR业务的高效保护。仿真结果表明,所提算法有效地降低了保护冗余度和备选圈规模,能够为DR业务提供可靠的保护。Power demand response service develops rapidly in recent years, and survivability of the power communication network its transmission depends on attracts more and more attention. By studying the way of network coding P-cycle for link protection and combining flow characteristics of demand response business, this paper proposes a demand-response-oriented network coding P-cycle algorithm（DR-NCPC）. Firstly, the characteristics of flow direction and reliability requirements of DR business are analyzed. Secondly, the alternative P-cycle set is expanded according to DR business characteristics, so as to realize efficient protection of DR business. Simulation results show that the proposed algorithm can effectively reduce redundancy and the number of alternative cycles, and provide reliable protection for DR services.
