摘　　要：为了对感应耦合无线电能传输的城市轨道交通供电技术进行可靠性分析,研究基于模糊故障树对供电系统故障进行穷举,分析故障树底事件的临界重要度,并引入熵权法,层次分析法和博弈论组合赋权法对系统的运行状态进行可靠性的模糊综合评价。实验表明,层次分析法计算出权重整体上比其他方法得出的权重差异性更大,波动幅度较大,区间在0到1.0之间,权重系数的权重最小,但是波动稳定。经过博弈论组合赋权法处理后的权重情况,整体趋势与3种单独方法得出的权重比较相似,并且权重值较为均衡,对松耦合变压器故障情况的分析得出底事件11对顶事件的影响最小,概率为0.948 9。对供电系统的可靠性分析对城市轨道供电系统的质量提高提供了理论基础。In order to analyse the reliability of the power supply technology of urban rail transit with inductively coupled wireless energy transmission,the study is based on the fuzzy fault tree to exhaust the faults of the power supply system,analyses the critical importance of the fault tree events,and introduces fuzzy comprehensive evaluation of the reliability of the system's operation state by the combination of the entrepreneurial weighting method,hierarchical analysis method,and the assignment method of the game theory.The experiment shows that the weights calculated by the Analytic Hierarchy Process have a greater overall difference than those obtained by other methods,with a larger fluctuation range between 0 and 1.0.The weight coefficient has the smallest weight,but the fluctuation is stable.The weight situation processed by the game theory combination weighting method shows that the overall trend is similar to the weights obtained by the three individual methods,and the weight values are relatively balanced.The analysis of the fault situation of loosely coupled transformers shows that event 11 has the smallest impact on the top event,with a probability of 0.9489.The reliability analysis of the power supply system provides a theoretical basis for improving the quality of urban rail power supply systems.
