  如何构建智能电网的无线数据集中器

  本文讨论如何为智能电网构建一个数据集中器,它使用传入数据来减少无功损耗,并处理诊断和故障检测。它着眼于无线技术,如cc1120和接口与控制器的智能能源设计如处理器Sitara AM335x线优化。

  智能电表正在迅速部署,以满足这项技术在欧洲范围内达到百分之八十的家庭2020的任务,而实现这一目标的关键技术之一是使用集中器。每台安装的电表直接与公用服务器通信的技术和经济挑战使得一对一的解决方案很难实现,因此集中器是支持大型安装的自动计量基础设施(AMI)的关键方法。

  通过自动抄表(AMR)测量,仪表数据与中央计费站的通信将是无缝的。除了收集用于计费的能源使用信息外,公用事业提供商还可以使用AMI分析计量网络中的故障,并在不需要工程师的情况下远程找到解决方案。

  The data concentrator is a critical node in the AMI, connecting several utility meters to a central utility server, simplifying the communication links of the energy service provider. These are used at several points in the infrastructure to securely aggregate data from a manageable number of meters and relay the information to the centralized utility servers.

  The connection between the meters and the concentrator can be handled in several ways, but wireless is emerging as a cost effective and efficient way of linking multiple meters to a central aggregator. The frequency of the data fed back to the central servers ranges from an hourly feedback meter to real-time meters with a built-in two-way communication structure. These systems have the capability of recording and transmitting instantaneous information, providing more information on the load of the various end points that are actively consuming energy.
