Abstract

The invention discloses a power distribution terminal based on a ColdFire architecture. The power distribution terminal comprises a Coldfire processor, a three-remote functional module and a transceiver with a built-in high-precision IEEE (Institute of Electrical and Electronics Engineers) 1588 clock, wherein the Coldfire processor is connected with the three-remote functional module, and the Coldfire processor is connected with the transceiver. Circuit protection and network distribution three-remote functions are integrated in the power distribution terminal, the synchronous sampling and control on voltage and current in eight loops are realized, and intelligent power distribution and protection functions are realized. The power distribution terminal has the functions of a universal distribution network automation terminal. A high-precision synchronization function is realized through the adoption of the transceiver with the built-in high-precision IEEE 1588 clock.

Description

[0001] technical field [0002] The invention relates to the field of distribution network automation and relay protection, and more specifically, to a power distribution terminal based on ColdFire architecture and supporting IEEE1588. [0003] Background technique [0004] With the development of communication technology, the smart grid technology based on communication technology is more and more deeply applied in the power system.
