一体化装置故障诊断及系统可靠性规划研究*

针对一体化装置的故障预测难题,提出了一体化装置故障诊断模型。通过对模型进行分析,找出系统主要的故障元素及各子系统的故障概率,根据系统可靠性理论,从提高系统可靠性的角度出发,提出了可靠性规划方法,以各个装置分配备用装置的顺序为阶段和装置间所允许使用的总备用个数为状态变量,对主要故障元素进行可靠性规划。最后通过仿真分析,大幅度提高了一体化装置的安全稳定性,结果表明了所提方法的可行性和有效性。

Research on integrated device fault diagnosis and system reliability planning

This paper considered an integrated device failure prediction problem,and proposed an integrated device of failure diagnosis model,through analyzing this model,found the main elements of the system and the subsystem failure probability.Based on the system reliability theory to improve the system reliability,it gave the reliability programming algorithm,according to the phases and the state variables of the device’s sequences of standby equipments and the number of standby equipments allow to used between the device,programmed the key failure elements.Finally,through the simulation analysis,it improves the system security and stability greatly.As a result,the application of this method indicates that the method is rational and efficient.
