| 摘 要： | IEC 61508和IEC 61511等标准针对连续工艺装置提出了安全仪表系统安全完整性等级评估方法。但对于间歇装置的SIL评估，受人因因素影响水平并未明确，且没有提出相应计算模型。以某六氟磷酸锂间歇生产装置典型SIS为例，采用HAZOP结合LOPA方法对其进行风险分析，在明确间歇生产装置存在人员中毒、窒息及燃烧爆炸风险的基础上，确定并验证其安全仪表系统的SIL，再依据间歇生产装置人工依赖性高，即部分安全仪表系统未接入自动联锁且需人工手动触发的特点，建立人因可靠性模型，来分析人因可靠性对安全仪表系统SIL的影响，并进行改进研究。研究结果表明:人因因素对安全仪表系统SIL有显著影响；可通过改变SIS元件冗余结构、测试策略并结合改进人因管理措施来提高SIL。

| Abstract: | The assessment methods of safety integrity level (SIL) for safety instrument system (SIS) aiming at the continuous process equipments have been put forward in IEC 61508 and IEC 61511. However, for the SIL assessment on the batch equipments, the influence level of the human factors has not been identified, and the corresponding calculation model has not been proposed. Taking the typical SIS of a batch producing equipment of LiPF6 as example, the risk analysis was carried out by using the hazard and operability analysis (HAZOP) combined with the layer of protection analysis (LOPA). On the basis of determining the risk of personnel poisoning, asphyxiation, and combustion and explosion of the batch producing equipment, the SIL of SIS was determined and verified. According to the characteristic of high artificial dependence of the batch producing equipment, namely part of the SIS were not connected into the automatic interlocking and needed to be manually triggered, a model of human reliability was established to analyze the influence of human reliability on the SIL of SIS, and the improvement research was conducted. The results showed that the human factors have significant influence on SIL, and SIL can be improved by changing the redundancy structure and testing strategies of SIS components, combined with improving the human factor management measures. |
