基于改进Bow-tie模型的动力管道风险分析

Power Pipeline Risk Analysis Based on Improved Bow-tie Model

通过人为、自然、设备和管理4个因素分析动力管道失效原因,把动力管道失效所带来的后果划分成安全、经济、环境和社会4个方面进行分析,确定了动力管道泄漏的防控措施。运用改进Bow-tie模型分析动力管道失效问题,有效降低了管网事故发生率。

The failure reason of power pipelines were analyzed from four aspects of the artificial,nature,equipment and management.Through having the consequences caused by the failure of power pipelines divided into the safety,economy,environment and society for analysis,and the prevention and control measures of the power pipeline leakage were determined.Applying the improved Bow-tie model to analyze failure of the power pipeline can reduce accident rate of the pipeline network effectively.
