Based on the special dynamic load characteristics of rail transit,the transient-based protection software and hardware for rail transit are designed.The real prototype is made on the basis of studies of dynamic load monitoring+traveling wave signal measurement in terms of software and hardware,realizing of identification of panoramic feature of fault signal of rail transit line and setting up of panoramic feature database of fault.The identification and monitoring system for fault of OCS of rail transit with function of simulation+real measurement is developed and it has been applied at the site of the rail transit line.The study has achieved certain results in the development of traveling wave signal demodulator,the application of traveling wave to accurately locate fault location and the independent development of upper computer software combined with wavelet transform algorithm,providing strong support for improving the reliability of transient-based protection of rail transit power supply lines.
