Abstract:

As the first defensive line of power grid security,the right actions of delay protection devices can minimize the influence to the electric power system security caused by system or equipment failures.Based on the research of relay protection device inspection procedures and enterprise standard of electric power industry,the embedded software testing content and technologies of relay protection device were studied,including functional testing,performance testing and fault injection testing.This research contributes to the completeness and correctness of the embedded software testing about relay protection device.

Key words: relay protection device, functional testing, performance testing, software fault injection
