城市中压配电网接线模式识别

在配电网的评估、改造和规划中，网架结构十分重要。配电网的接线模式是网架结构的基本反映。为解决对实际配电网进行网架结构分析时数据多，工作量大，分析比较困难的问题，提出了一种基于网络拓扑分析和模式识别理论的城市中压配电网接线模式识别方法。该方法结合了中压配电网的结构特点和各种典型接线模式的具体特征，可有效地自动识别城市中压配电网的典型接线模式，以利于全面了解中压配电网结构特征，发现其薄弱环节，这对接线模式的简化和标准化具有重要意义。

AUTOMATIC IDENTIFICATION ON CONNECTION MODES OF URBAN MIDDLE VOLTAGE DISTRIBUTION SYSTEM

Network structure is the focus in the evaluation, reform and planning of middle voltage distribution systems. After long-term development of distribution systems, there are various network connection modes, which represent main characteristic of network structure. Some studies on connection modes from the technical and economic view have been performed. Nevertheless, literatures on recognition of these modes are hardly found. Data of a practical urban distribution system is so huge that it is difficult and time-consuming to analyze connection modes. In order to solve this problem, an approach for automatic identification on connection modes of urban middle voltage distribution system is presented on the basis of network topology analysis and pattern recognition, which integrates characteristic of the connection modes with structure characteristic of urban distribution system. This approach is significant for overall understanding the structural features of middle voltage distribution network, finding out its weak links and further simplification and standardization of connection mode.
