摘 要：貝葉斯網(wǎng)絡(luò)是研究不確定性問題的重要方法之一，把貝葉斯網(wǎng)絡(luò)法用到牽引變電所的可靠性評(píng)估中，結(jié)合牽引變電所電氣主接線的故障樹和最小路來建立貝葉斯網(wǎng)絡(luò)。通過故障樹的貝葉斯網(wǎng)絡(luò)計(jì)算了其可靠性指標(biāo)，能夠有效地識(shí)別系統(tǒng)的薄弱環(huán)節(jié)，實(shí)現(xiàn)了牽引變電所可靠性的定性和定量評(píng)估。用基于最小路的貝葉斯網(wǎng)絡(luò)對(duì)上面的可靠性指標(biāo)進(jìn)行了驗(yàn)證，為牽引變電所可靠性評(píng)估提供了新的方法。

Abstract: Bayesian network (BN) is one of the most effective tools to study uncertain problems. This paper used BN method to evaluate the reliability of traction substation. The fault tree and the minimal path of main electric connection of traction substation were combined to build Bayesian network. This paper calculated its reliability index through Bayesian network of the fault tree, which could effectively identify the weakness of the system, to realize the qualitative and quantitative assessment of reliability in traction substation. The mentioned reliability index above is verified by Bayesian networks based on the minimal path, which provides a new method for the assessment of traction substation reliability.
Key words: Bayesian network; traction substation; reliability assessment; fault tree; minimal path
