摘要
高速铁路牵引供电系统运行过程中,会出现异常故障造成的应急状态运行方式。通过由正常的全并联AT供电方式变化为直接供电、半直供电半AT供电、越区供电等应急状态下的不同运行方式,获得多种牵引供电系统运行方式的试验数据,验证应急状态下供电方式对应的供电能力、保护设置等,为接触网或变电设备出现故障时的应急处置提供试验数据支撑,以应对运营中可能产生的风险,保障高速列车的安全运行。
During the operation of traction power supply system of high-speed railway,there will be emergency operation mode caused by abnormal faults.By changing the normal all-parallel AT power supply mode into different operation modes under emergency condi⁃tions,such as direct power supply,semi-direct power supply and semi-AT power supply,and cross-district power supply,obtained re⁃lated test data of various traction power supply system in its operation modes.These provide test data supports for emergency solutions when catenary or substation equipment fails,so as to cope with possible risks in operation and ensure the safe operation of high-speed trains.
