摘　　要：随着配电网的不断发展与扩大,网架拓扑结构不断扩张,最终会造成配电网网架结构愈加复杂与臃肿,许多规划之初避免的拓扑结构问题也日益显现。针对这一问题,提出了基于公共信息模型(CIM)的配电网网架拓扑结构问题优化方案。首先对CIM原有的数据进行简化与重构,提取出其中拓扑相关信息,极大减小了数据存储规模,简化了运算方式,为后续大数据规模应用提供了条件。其次提出了两种配电网典型网架拓扑结构问题的定义,并以降低配电网停电时户数为目标函数,提出了具体的网架优化方案。最后以某市实际网架数据为算例,对该方案进行了实例验证,最终的优化方案结果也得到了一线工程师的认可,表明所提出的网架优化方案可有效辨识出配电网中存在的网架问题,并提出相应有效的网架优化方案。With the continuous development and expansion of the distribution network,the network topology continues to expand,which will eventually cause the distribution network structure to become more complex and bloated,and many topology problems avoided at the beginning of planning are also emerging.To solve this problem,an optimization scheme of distribution network topology based on common information model(CIM)is proposed.Firstly,the original CIM data is simplified and reconstructed,and the topology related information is extracted,which greatly reduces the data storage scale,simplifies the operation mode,and provides conditions for the subsequent large-scale application.Secondly,the definitions of two typical distribution network topology problems are proposed,and the specific network optimization scheme is proposed with the objective function of reducing the number of households in the distribution network.Finally,the actual grid data of a city is taken as an example to verify the scheme.The final optimization results are also approved by the front-line engineers,which shows that the grid optimization scheme proposed in this paper can effectively identify the grid problems existing in the distribution network,and put forward the corresponding effective grid optimization scheme.
