配电网络的可观测性与自动化水平密切相关。针对配电网络自动化终端优化配置问题,提出了一种计及可观测性的数学优化模型。该模型综合考虑了自动化终端类型选择、安装位置优化以及可观测性与投资成本的平衡等因素,利用Distflow潮流方程和二阶锥松弛技术对原问题进行转化,建立了一种混合整数二次规划模型,设计了自动化终端优化配置求解流程,并通过仿真分析验证了所提模型与方法的有效性。结果表明,合理配置自动化终端,可在保证较高可观测性水平的同时,显著降低配电网自动化投资成本,为配电自动化建设提供了有益参考。

The observability of distribution networks is closely related to the level of automation.This paper proposes a mathematical optimization model that takes into account observability to optimize the configuration of distribution network automation terminals.This model comprehensively considers multiple factors such as the selection of automation terminal types,optimization of installation locations,and the balance between observability and investment costs.The Distflow trend equation and second-order cone relaxation technique are used to transform the original problem,and a mixed integer quadratic programming model is established.The optimization configuration solution process for automation terminals is designed,and the effectiveness of the proposed model and method is verified through simulation analysis.The results indicate that reasonable configuration of automation terminals can significantly reduce the investment cost of distribution network automation while ensuring a high level of observability,providing useful reference for the construction of distribution automation.
