The invention discloses an availability evaluation and monitoring method for a hydrogen power train traction system. The method comprises the following steps: acquiring the accumulated fault frequency of the hydrogen power train traction system, the preventive maintenance frequency of the system, the average maintenance interval time of the system, the total fault repair time of the system, the total preventive maintenance time of the system and the shutdown time of the system; based on the average maintenance interval time of the system and the shutdown time of the system, establishing an availability evaluation model of the hydrogen power train traction system in the evaluation period, and comparing the availability evaluation model of the hydrogen power train traction system in the evaluation period with a preset availability alarm lower limit value; and according to the comparison result, carrying out monitoring and over-limit alarming on availability judgment of the hydrogen power train traction system. According to the method, the availability of the traction system can be comprehensively and accurately evaluated, and the availability of the traction system can be subjected to over-limit alarm, so that the availability of the traction system is controlled within a required range.
Description
technical field [0001] The invention belongs to the technical field of availability of hydrogen-powered train traction systems, and in particular relates to a method for evaluating and monitoring the availability of hydrogen-powered train traction systems. Background technique [0002] As a member of new energy trains, hydrogen-powered trains have great advantages in energy saving, emission reduction, economical and environmental protection, and have received widespread attention in recent years. The traction system is a key system of hydrogen-powered trains, and its availability plays a very important role in the reliability and safety of hydrogen-powered trains. The availability of the traction system is affected by the number of failures, the average preventive maintenance time, the preventive maintenance interval, the time per repair, and the failure rate. Therefore, the availability evaluation of the traction system should consider the influence of all the above factor...
