　　数据集中器将AFE，MCU和无线电智能电网效率的关键

　　数据集中器提供通信关键自动计量和信息在智能电网架构系统。数据集中器通常位于电网中的变压器或变电站级，数据集的完整性和安全性保证了智能电表的能量测量信息和电力应用的分析信息。通常，这些系统使用先进的基于MCU的设计，依赖于电力线通信（PLC）在最后一英里的用户仪表和能源管理系统。为了满足广泛的这些设备的要求，工程师可以设计复杂的基于PLC的数据集中器采用AFE集成电路和MCU厂商，包括飞思卡尔半导体、集成、意法半导体、德克萨斯文书，其中。

　　数据集中器充当公用事业控制的智能电网分销网络和终端用户之间的接口，管理特定地理区域内公用事业和多个智能电表之间的数据交换（图1）。在自动计量基础设施（AMI）和自动抄表（AMR）系统、数据集中器–也称为数据聚合–提供所需的测量、分析的核心功能，并收集能源使用。然后他们将这些数据传送到中央数据库进行计费、故障排除和分析。

　　Data concentrators enable utilities to use information from smart meters to gain a better understanding of grid status， including immediate knowledge of outages. With this detailed information about the power distribution grid， power companiescanevaluate overloads and unbalances in the grid， as well as more effectively detect faults. This information also allows utilities to evaluate more static losses in the grid by comparing measured power at higher levels of the grid with that measured by smart meters at the periphery of the grid. Ultimately， the combination of detailed smart meter power measurements and upstream monitoring and analysis will provide utility customers with better knowledge of their consumption and power saving opportunities， and inform them about network situation disturbances.
