| 中文摘要: |
| 质子交换膜燃料电池(PEMFC)电站涉及大量高压氢气的制备、储存、运输和使用等,设备繁多、工艺复杂,其安全运行至关重要。现有研究缺乏对PEMFC电站安全性的系统分析。针对某PEMFC电站,使用危险与可操作性分析(HAZOP)、事件树分析和风险矩阵分析建立了一个完整的分析框架,对电站各子系统的安全性进行了分析和概率计算。结果表明电站存在诸多风险且概率普遍偏高,电站整体安全性较低。其中发电系统风险最高,是安全性最低的一个子系统,而在电站所有风险中,设备气压异常风险最为常见,占比近1/3。进一步通过设置报警、散热、限流、排水装置等基本保护层和安全联锁系统(SIS),将事故发生的概率降低至社会可接受风险范围。研究结果可为研究PEMFC电站安全风险的分析方法和管控措施提供参考。 |
| 英文摘要: |
| Proton exchange membrane fuel cell (PEMFC) power plants involve the preparation, storage, transportation, and use of a large amount of high-pressure hydrogen, consisting of many equipment and complex processes. Thus, its safe operation is crucial. Existing research lacks a systematic analysis of the safety of PEMFC power plants. This work established a complete analysis framework for a PEMFC power station using Hazard and Operability Analysis (HAZOP), Event Tree Analysis, and Risk Matrix Analysis. The safety of each subsystem of the power station was analyzed, and probability calculations were carried out. Results indicate many risks, and the risk probability is generally high in the power station, posing significant safety concerns. The power generation system shows the highest risk and lowest safety among various subsystems. Among all the risks in the power station, the risk of abnormal equipment pressure is the most common, accounting for nearly one-third. Furthermore, the probability of accidents can be reduced to a socially acceptable risk range by setting up basic protective layers such as alarms, heat dissipation, current limiting, drainage devices, and safety interlock systems (SIS). These results can provide a reference for the analysis methods and control measures of safety risks in PEMFC power plants. |
