the secondary fault and fault analysis mainly relies on the tester for off-line analysis system. The results of this analysis are difficult to achieve the same on-line test effect as the operation of the system. A novel processing equipment is proposed
which can transfer Comtrade file to IEC 61850 and send generic object oriented substation event(GOOSE)and sampling value(SV)message based on transfer results
so that the operator and maintainer are enabled to make on-line fault analysis on site. The device hardware
mapping between IEC 61850 and Comtrade
synchronous output function design of SV and GOOSE are described.
