| 摘 要： | 指出在高速铁路牵引供电系统故障诊断中应计及所获取的保护和开关动作信息的不确信性和模糊性,基于此,将模糊Petri网(fuzzy Petri net,FPN)应用于牵引供电系统的故障诊断.考虑到牵引供电系统保护的特殊性,进行了第2次推理；针对越区供电时馈线远后备保护覆盖元件多的特点,增加了推理条件以保证推理的正确性；根据...

| Abstract: | It is pointed out that in the fault diagnosis of traction power supply system for high-speed railway the uncertainty and fuzziness in the obtained action information of protective relayings and circuit breakers should be taken into account.For this reason,the fuzzy Petri net is applied in the fault diagnosis of traction power supply system.Considering the particularity of protective relayings for traction power supply system,the second reasoning is conducted.In allusion to the feature that more components a... |
