摘 要: 采用贝叶斯网络法对组合式同相供电牵引变电所主接线可靠性进行评估,并提出改善牵引变电所主接线可靠性的措施。结合组合式同相供电牵引变电所自身的结构特点,建立相应的基于故障树的贝叶斯网络。然后结合实际的山西沙峪牵引变电所主接线进行分析,计算出山西沙峪牵引变电所主接线可靠性指标结果,并且能够有效地找出变电所供电的薄弱环节。然后从薄弱环节入手,提出改善组合式同相供电牵引变电所可靠性的措施。

Abstract:The Bayesian network (BN) method is used to evaluate the reliability of the traction substation of combined co-phase power supply and to propose the method that can improve the system reliability.Combined with the structural features of traction substations ,different types of Bayesian networks are built that are based on the fault tree.According to the traction substation of combined co-phase power supply in Shayu,Shanxi ,the reliability results can be evaluated and the weak links of the system could be identified .Considering the weak links, two methods that can improve the system reliability have been proposed.

 

Key words: combined co-phase power supply;Bayesian networks;reliability assessment
