Abstract

The invention discloses a method for determining a maintenance scheme of a traction power supply system which reduces maintenance power outage time. The method includes the following steps: A: Obtaining input data required for maintenance plan determination. B: Determine the value of the reliability maintenance margin ΔR of the traction power supply equipment. C: Solution of maintenance cycle, required maintenance equipment and maintenance power outage time. D: Change the value of the reliability maintenance margin ΔR of the traction power supply equipment, repeat step C, and select the power outage time T f The reliability maintenance margin corresponding to the minimum value of , the maintenance cycle and the equipment that needs to be repaired in each maintenance cycle are taken as the final output maintenance plan. The invention can reduce the maintenance power outage time of the traction power supply system, and provides a good basis for the railway operation and maintenance unit to formulate the maintenance plan of the traction power supply system.

Description

technical field [0001] The invention relates to a method for determining a maintenance plan for a traction power supply system, in particular to a method for determining a maintenance plan for a traction power supply system that reduces the maintenance power outage time. Background technique [0002] my country's railway traction power supply system adopts a maintenance mode that combines regular planned maintenance, breakdown repair and daily inspection. This maintenance mode based on regular planned maintenance can guarantee the reliability requirements of traction power supply equipment to a certain extent, but there are problems of frequent maintenance, high cost and low efficiency. Since the maintenance of traction power supply equipment relies on manual operation, the entire network or region needs to cooperate with power outages. Therefore, frequent maintenance increases the power outage time of the traction power supply system, which may not only affect the operatio...
