大型发电机组安全风险定量评价方法和应用

Development and Application of Quantitative Risk Assessment for Large Capacity Power Generating Units

提出发电机组部件和设备的静态风险与动态风险的定量评价方法,采用风险排序数定量描述发电机组的风险;给出了发电机组部件的故障概率、故障后果与故障发生可能性系数的计算方法、发电机组部件与设备安全等级的划分方法以及应用实例.该方法为发电机组部件与设备的定量风险评价提供了新的技术手段.

A quantitative method is presented for assessment of static and dynamic risk of components and equipment for power generating units,in which the term of risk priority number is used to quantitatively describe the risk.Calculation methods are put forward for the fault probability,fault consequences and likelihood coefficient of fault occurrence,while safety grade classification method proposed for components and equipment of power generating units,together with some application examples.This may serve as a reference for quantitative risk assessment on components and equipment of power generating units.
