Abstract:

Intelligent power distribution terminals are installed at the switching nodes of smart distribution grids for data collection, fault detect, self-healing control, communication, information exchange with higher level of power distribution automation system, consisting a critical part of the smart distribution grids. Based on regular power distribution terminal, a design method for new type of intelligent power distribution terminal is provided in the paper, the design methods of hardware framework, hierarchical and modulized software framework are also proved. To build the hardware platform, the hardware framework adopts the ARM9 series based i.mx28 chipsets and ADSP-BF518 based DSP chipsets. The software platform adopts the architecture based on embedded Linux system, SQLite database and real-time database/information data. To introduce the intelligent power distribution terminal in detail, the system support layer, basic function layer, management/maintenance layer, business application layer of software platform are described in the paper, the hardware platform and the architecture, application layer, hardware related layer, power-supply system, and the method of standard design are also described.

Key words: Intelligent power distribution terminal, framework design, hierarchical modular design
