中文摘要：

随着分布式能源、微网以及高级量测体系等在智能配电网中的接入和应用,智能配电网中的信息流量将远大于现有配电网。为了保证智能配电网信息网络的可靠性以及经济性,需要对其进行合理规划。文中从智能配电网信息网络的可生存性出发,采用N-1准则构建优化模型,并提出了一种启发式算法来保证模型的顺利求解。最后,通过某县级配电网信息网络规划算例,将启发式算法与1+1保护优化模型进行了比较,结果表明,启发式算法能够满足网络规划的可生存性约束。

英文摘要：

With the access and application of distributed energy,microgrid and advanced measurement infrastructure in smart distribution network,the volume of information in a smart distribution network will be much greater than current distribution networks.In order to ensure the reliability and economy of the information network,optimal planning is needed.An optimization model is given for the survivability of the smart information network by using the N-1 criterion.A heuristic algorithm is proposed to solve the model successfully.Finally,the heuristic algorithm is compared with the 1+1 protection optimal model in an example of distribution information network planning for a county,the results showing that the heuristic algorithm can satisfy the survivability constraints of network planning.
