The invention provides a power distribution automation terminal in a standard system framework, and belongs to the automation field of power systems. A distributive modular design scheme is adopted, and each functional plate element is mutually independent; an ARM-DSP-based embedded system dual-core design scheme is adopted, a data processor DSP carries out processing on a bottom-layer task, and a main processor ARM carries out processing on a high-layer task; and each function module of the data processor DSP and the main processor ARM is distributed in each of different functional application layers according to characteristics of each module. The power distribution automation terminal provided by the invention has the advantages of configuration flexibility, function modularization, model standardization, high interoperability and the like, and the power distribution automation terminal can be pushed to develop rapidly.
