Abstract: The verification time of special logic accounts for a large proportion in the secondary intelligent equipment overhaul of intelligent substation.To shorten the verification time of special logic is an important task to reduce the power outage overhaul time and ensure the reliability of power supply.A special logic verification software for secondary equipment of intelligent substation was introduced.The smart station secondary equipment was reclassified.The question and answer table and circular judgment method was adopted.The correctness of the final results can be automatically determined by the test situation,and the standard test reports were generated.Through on-site commissioning,testing and application in actual production of the power grid in Zhangzhou,it proves that it can effectively shorten the special logic checking time,reduce power outage time and generate benefits.

Key words: intelligent substation, secondary equipment, special logic check, overhaul
