The Research Of Distributed Fault Recorder In Substation

The trend of today's power system is expansion of networks and interlink of local area networks, and the performance of power system is more and more difficult. The increasingly complexity of power system requires more higher demand to fault recorder which is as necessary tool as power system fault analysis. And the appearance of DSP, high performance microcontroller and field bus provides essential condition for improvement of the performance of microcomputer-based recorder. This paper presents a design scheme of distributed fault recorder device based above technologies and states its structure of software and hardware and its performance with details.
