摘　　要：流传输控制协议(SCTP)可以在电力通信网络与输电线路同时发生故障时实现广域后备保护迅速可靠动作.针对主路径性能急剧下降但仍未发生断开错误时广域后备不能及时动作问题,首先分析了基于时延的主路径自动切换方法和基于路径综合评价主路径自动切换方法,随后,将基于路径综合评价主路径自动切换方法引入广域后备保护信息通信传输中,最后,通过NS2仿真实验环境进行了验证.实验结果表明,基于路径综合评价的主路径自动切换方法降低了主路径自动切换时间,提高了广域后备保护通信传输的可靠性.Stream transmission control protocol （SCTP） in the electric power communication network and transmission line can be failed simultaneously onto both fast and reliable Wide-area backup protection ac- tion. However, when the primary path failure results in performance degradation and disconnection when error occurs, the problem mentioned above leading Wide-Area backup would not be timely acted. To solve this problem, the main path was analyzed based on delay automatic switching paths comprehensive evaluation method which was based on the primary path automatically switching method. The main path automatically switched Wide-area backup protection of information and communication transmission were also introduced. The NS2 simulation environment is verified. Experiments show that the path-based com- prehensive evaluation method of main path automatically switch the primary path reduces time consump- tion and improves wide-area backup protection communication transmission reliability.
