Abstract：To improve thecommisioning eficiencyandreliabilityof therelayprotection system forinteligent tractionsubstationsof high-speedrailways，this studytakes thescdfileasthecore，constructsaful-digitalclosed-loop test system basedon svand goose messages，and analyzes its key mechanisms.aiming at the special operating conditions of the high-speed railway traction power supplysystem，such as single-phase ac 25 kvsystem，severe load fluctuations，and frequentregenerative braking，a commisioning modeling method oriented to traction characteristics is proposed.taking a section ofthe guinan high-speed railway as an engineering case，the optimization efects of the simulation environment constructedbydigital testers in terms of protection configuration consistency，action delay control，self-healing reconfiguration logicverification，andabnormal fault toleranceareanalyzed.theresults show thatthe commisioning systemcan shorten the joint commissioning cycle to within 1 day，control the message error within 20μs ，and the self-healing response time is less than 3 seconds，which significantly improves the reliability and adaptability of the system under complex operating conditions.
