| 摘要: |
| 构建了中压配电网分析模型来梳理和规范10 kV主干网架结构。首先，结合中压配电网分层分区的基本思想，定义了10 kV主干网络和次级网络的概念，明确了中压配电网的层次结构及功能定位；其次，结合中心城区配电网高供电能力、高可靠性的需求，构建了基于开关站供电模式的典型供电块联络模型、变电站及开关站空间布局的约束性分析模型。以上工作为主干网络供电能力水平的提高及供电范围的合理规划奠定了理论基础；最后，根据某城市中心城区配电网运行的实情，制定参数的边界条件，进行模型的分析和计算，验证了所提模型的合理性和有效性。 |

| Abstract: |
| An analysis model of medium voltage distribution network is built for analyzing and generalizing the structure of 10 kV backbone network. Combined with the basic concept of layered and blocked medium distribution network，the concept of 10 kV backbone network and secondary network are defined to set the hierarchy and functional orientation of medium voltage distribution network，and combined with the requirements for high power supply ability and reliability of distribution network in center area，a contact model of typical power block and a binding analysis model of space distribution for substations and K-stations are constructed based on K-type power supply mode，which provides the theoretical basis for improving the power supply level of backbone network and properly planning the power service areas. To verify the rationality and validity of the proposed model，the parameter boundary conditions of a distribution network in center area are set according to its actual operational situation and the corresponding model analysis and calculation are carried out. |
