摘要

摘要: 智能电网中分布着大量的无线传感器用于监测智能电网设备和用户的运营状态信息，原始监测数据都采集到数据处理中心会给数据采集通信网络带来极大的数据流量压力。采用在数据采集过程中进行数据聚合的策略，将极大地缩减数据流量，降低通信网络的开销。因此聚合节点的选择以及聚合拓扑的构造成为智能电网数据采集的关键问题。该文提出一种基于层次聚类的异步分布式聚合布局构造算法。该算法首先按照层次聚类把所有节点按照距离的远近聚合构造出一棵采集树。随后计算出最佳分组数，按照该分组数进行分组。然后按照异步分布式策略进行最佳聚合节点的选择以及最佳传输拓扑的构造。仿真实验表明，该算法可以快速找到具有最小开销的数据聚合方式，提高智能电网数据采集网络的效率。

Abstract: Large-scale of wireless sensors are distributed to monitor smart grid equipment and user,s operating status information in smart grid. The original monitoring data are all collected to data processing center. And it brings huge data traffic pressure for communication network. Thus it is necessary to use data aggregation strategy in the process of data collection to reduce data traffic greatly, and reduce the overhead of communication network. This paper proposes asynchronous distributed aggregation layout construction algorithm based on hierarchical clustering. Firstly, a collection tree is constructed with the distance of all the nodes based on hierarchical clustering. Then the optimal numbers of clusters and group are calculated. And then, this paper selects the optimal aggregation nodes and constructs the best transmit topology with asynchronous distributed strategy. Finally, the simulation experiment shows that the algorithm could find the data aggregation mode of minimum cost quickly, and improve the efficiency for data collection in smart grid.
