| 摘 要： | 目前满足系统保护通信网络的路由算法是在综合时延和可靠性的要求下，计算一条快速且可靠传输的路径，而没有考虑到当电网发生故障或网络中通信量过大时，通信网络中许多节点的排队时延会极大地增加，忽略排队时延对路径传输总时延的影响会导致路径的错误选择，从而影响系统保护的实时性。针对此问题，提出了一种考虑排队时延的路由选择算法，用于计算信息传输总时延最小的最优路径，以提高系统保护通信的实时性。实验结果表明，通过本文提出的路由选择算法计算得到的路径在满足系统保护可靠性要求的基础上信息传输总时延最小。

| Abstract: | Currently,a fast and reliable transmission path was calculated by routing algorithm that satisfies the system protection communication network under the requirements of delay and reliability,without considering that when the grid fails or the traffic in the network is excessive,the queuing delay of many nodes in the communication network will greatly increase.Aiming at this problem,a routing algorithm was proposed to solve the minimum queuing delay and improve the real-time performance of wide area protection.Experimental results show that the total information delay of the path calculated by the routing algorithm proposed is the smallest under the requirements of system protection reliability. |

| Keywords: | system protection real-time queuing delay routing selection reliability |
