摘　　要：建立了城市高压配电网的接线模式模型,并基于该模型提出了接线模式自动识别方法。首先,该方法对城市高压配电网接线模式经过概括和抽象,形成了电源、网架、负荷三层体系结构,并建立各自的数学模型。其次,基于网络拓扑分析,形成"电源-网架-负荷"供电关系及"网架-网架"联络关系。最后,分别分析并提取三层体系中的典型特征元素,利用模式识别理论达到接线模式识别的目的。此外,对国内常用典型接线给出了模式识别的特征表达式并建立接线模式特征库;对国内非典型接线通过确认其合理性后添加到特征库中,如不合理则会给出说明。实例表明,本方法可以有效识别高压配电网接线模式,也适用于中压配电网电缆网接线模式识别。This paper built the connection mode model of urban high-voltage distribution networks, and then proposed automatic identification methods for the connection modes. Firstly, the connection modes of urban high-voltage distribution were summarized and abstracted to get a ＂power-grid-load＂ three-layer architecture and mathematical models were built separately for each layer. Secondly, based on the analysis of network topology, the ＂power-grid-load＂ power supply relationship and the ＂network-network＂ connection relationship were developed. Finally, typical characteristic elements were analyzed and extracted from three-layer architecture for connection mode identification, based on the pattern recognition theory. Moreover, the characteristic expressions of pattern recognition were presented and the feature database was built for the typical connection modes in China; the feature database also included reasonable untypical connection modes, and gave refusing reasons to the unreasonable ones. The examples show that this method can effectively identify the connection mode of high-voltage distribution network, and it is suitable for the connection mode recognition of cable network in medium-voltage distribution network as well.
