High-speed rail power supply part of the design of fault simulation experiment
Summary：High-speed rail power supply test system allows rail electrification relevant institutions and units comprehensive understanding of high-speed railway power supply system,.Fault simulation part is an important part of the high-speed rail power supply test systems, fault simulation portion can be intuitive simulation of high-speed rail power supply system ,produced some of the failures that can make you some faults on high-speed rail power supply system will be understood that.Because some of the fault simulation, then if something is not only dangerous, but also and especially the waste of resources. High-speed rail power supply test system failure part simulation of high-speed rail power supply system failure is a signal by simulating failure of the final output to achieve fault simulation, so the high-speed rail power supply test system failure In part, both to simulate failure of power supply system, and there is safety while also saving resources.
