Research and application of a new electrical fault recorder

SHE Li-huang,LUAN Xin-jun,ZHANG Shi,BAO Xi-rong(College of Information Science and Engineer of Northeastern University,Shenyang 110004,China)  
The paper describes the hardware and software design of a new type of electrical fault recorder.In order to satisfy the requirement of the high accuracy of the data,TMS320C33 is used to diagnose the electric power system and record the parameter of electric power system when an inaccuracy or an abnormity occurs.Adopt ColdFire 5282 as the main control processor,it is the bridge between PC supervision system and fault recorder.the processor which transfers watch orders and failure record has rich interfaces.ColdFire 5282 transplants the embedded operate system μClinux which introduces high performance of assignment management mechanism and file systems.This enhances the stability of the system.
