摘　　要：为分析西北大风区高速铁路接触网可靠性,提出将脉动风引起的弓网离线因素融合到接触网系统可靠性分析中,采用谐波叠加法模拟脉动风风速时程,利用高斯分布统计脉动风分布概率,通过GO-FLOW法构建接触网系统可靠性模型,运用MATLAB对融合弓网离线故障率接触网系统可靠性进行仿真,并与已有研究成果进行对比。结果表明:脉动风对弓网受流产生一定影响,融合弓网离线因素后,接触网系统可靠度明显下降。研究结果可为接触网可靠性研究提供新的思路。In order to analyze the catenary reliability of high speed railway in the Northwest gale area,the factor of pantograph-catenary disconnection caused by the fluctuating wind was integrated into the reliability analysis of catenary system.The harmonic superposition method was used to simulate the time history of fluctuating wind speed,and the statistics on the probabilities of fluctuating wind distribution was conducted by using the Gaussian distribution.The GO-FLOW method was used to construct the reliability model of catenary system,and the reliability of catenary system combined with the fault rate of pantograph-catenary disconnection was simulated by using MATLAB and compared with the existing research results.The results showed that the fluctuating wind had a certain influence on the pantograph-catenary current collection,and the reliability of catenary system decreased obviously when integrating into the factor of pantograph-catenary disconnection.The research results provide a new index for the study on the reliability of catenary system.
