Safety risk analysis of transmission line construction based on fuzzy fault tree

输电线路工程的安全建设对于保证电网发展质量具有重要作用,施工安全管理问题是工程建设安全和可靠性的潜在威胁。为此依据系统论的方法,提出了智能化建设中电力线路建设工程模糊故障树模型,并对基于基本事件与中高级事件概率的故障树逻辑结构进行分析,估算了事故发生的概率,最后结合实例进行了计算分析,结果表明所提方法可以对电力建设工程中倒塔事故进行有效分析。

The safe construction of transmission line projects plays an important role in ensuring the quality of power grid development,and construction safety management issues are a potential threat to the safety and reliability of project construction.For this reason,a fuzzy fault tree model for power line construction engineering in intelligent construction is proposed based on the method of system theory,and the logic structure of the fault tree based on the probability of basic events and intermediate and high-level events is analyzed,and the probability of accidents is estimated.The calculation and analysis are carried out with examples,and the results show that the method proposed can effectively analyze the collapsed tower accidents in power construction projects.
