Abstract

The invention discloses a reliability analysis method of a high-speed railway traction substation system, which comprises the following steps of: 1, defining an evaluation system of the high-speed railway traction substation system, namely, specifying a system range and defining a system reliability index; 2, determining a success guiding criterion and a reliability index of reliability modeling of the high-speed railway traction substation system; 3, taking the electrical main wiring of the high-speed railway traction substation as a research object, determining a GO-FLOW signal flow direction, selecting a proper operator, and establishing a GO-FLOW graph of the electrical main wiring of the traction substation; 4, inputting reliability parameters of each operator; 5, performing quantitative calculation and analysis on each operator of GO-FLOW to obtain steady-state and dynamic reliability indexes of the GO-FLOW; and 6, completing reliability evaluation of the high-speed railway traction substation system.

Description

technical field [0001] The invention relates to the field of railway traction power supply, in particular to a reliability analysis method for a high-speed railway traction substation system. Background technique [0002] With the large-scale construction of high-speed railway in our country, the reliability of traction power supply system has attracted great attention. As the core of the traction power supply system, the traction substation acts as a bridge connecting the external power system and catenary. Therefore, its failure will affect the normal operation of the high-speed railway and cause huge losses. In order to make the EMU run safely and stably, the reliability of the power supply of the high-speed railway traction substation must be guaranteed. [0003] Our country started earlier in the research on the reliability of power system and achieved many results, but there are few researches on the reliability of traction power supply system. At present, Chen Shao...
