因素变化过程中的系统故障模式动态识别方法研究
Research on dynamic identification method of system fault mode in the process of factor change
摘要
Abstract
To make up for the deficiency of identifying system fault mode by absolute fault number,we propose a dynamic identification method of system fault mode based on the change of fault number in the process of factor change.First,the change characteristics of fault data are provided by the characteristic function and fault distribution of space fault tree.Next,the connection number of set pair analysis is employed to express the certainty and uncertainty of identification,and the connection degree is calculated.Then,the dynamic identification degree is calculated to complete the dynamic recognition of fault sample mode.The feasibility of dynamic identification method of system fault mode is discussed.The dynamic identification process under the influence of single factor and multi factor is given.Finally,through the electrical system fault standard mode,the fault sample mode is identified,and the effectiveness of the method is verified.Thus,a novel method is new available for system fault mode dynamic identification.关键词
