摘　　要：【目的】调度数据网络拓扑结构复杂,设备众多,业务流量数据大,调度数据网的不稳定运行,最终可能造成一定规模的电网影响,对调度数据网静态拓扑结构进行可靠性评估,有着重要的现实意义。【方法】因此提出基于调度数据网络结构的可靠度评估模型。首先,在调度数据网拓扑结构分析的基础上,结合不同的连通可靠度算法计算网络连通可靠度,同时根据地区重要度,对调度数据网进行可靠度加权计算,得到综合可靠度,根据评估出的可靠度,可以作为网络优化或者可靠度预警的依据。【结果】本文以某省地区拓扑结构为例,进行可靠度评估,验证了该评估方法对调度数据网可靠度的评估的有效性和合理性。【结论】结果表明环型拓扑和并联结构可以有效地提高网络可靠度,助力调度数据网生产业务稳定快速发展。[Objective]The complex topology of the power dispatching data network,numerous equipment,large transaction flow data,and instability of the dispatching data network operation may eventually affect stability of a certain scale of the power grid.It is of great practical significance to evaluate the reliability of the static topology of the dispatching data network.[Methods]A reliability evaluation model based on dispatching data network structure is proposed.Firstly,based on the analysis of the topological structure of the dispatching data network,the connectivity reliability of the network is calculated by combining different connectivity reliability algorithms.At the same time,according to the regional importance,the reliability of the dispatching data network is weighted to obtain comprehensive reliability.The reliability obtained can be used as the basis of network optimization and reliability early warning.[Results]This paper takes the topological structure of a provincial power grid as an example to evaluate the reliability,and verifies the effectiveness and rationality of the evaluation method for the reliability of the dispatching data network.[Conclusions]The results show that the ring topology and parallel structure can effectively improve the network reliability and help the stable and rapid development of the production transaction of the dispatching data network.
