| 摘要: |
| 随着电化学储能电站装机容量的不断提高，其安全防控问题受到重视。为此，提出了基于主动风险源辨识、主动故障预防、主动事故处理的三道安全防线，构建了电化学储能电站的主动安全体系。第一道防线针对电化学储能电站的正常但不安全运行状态，快速、可靠地辨识风险源和安全诱因，不损失电站设备和运行能力；第二道防线针对已发生故障的不安全运行阶段，利用安全自动装置和安全监控系统，辨识并及时排除早期故障，尽量保持系统正常运行；第三道防线针对电化学储能电站的事故状态，进行事故特征分析、风险管控并实施联动预案，防止电化学储能电站崩溃与人员伤亡。基于三道安全防线实现电化学储能电站安全风险和事故的主动防控，可为储能电站的安全设计提供新思路。 |

| Abstract: |
| With the increasing installed capacity of electrochemical energy storage station, its safety prevention and control problem has been paid more attention. Therefore, three safety defensive lines based on active risk source identification, active fault prevention and active accident handling are proposed, and the active safety system of electrochemical energy storage station is constructed. The first safety defensive line aims at the normal but unsafe operation state of the electrochemical energy storage, which quickly and reliably identifies the risk sources and safety incentives without loss of station equipment and operation capacity. The second safety defensive line aims at the unsafe operation stage where faults have occurred, which identifies and timely eliminates early faults by using the safety automatic devices and safety monitoring systems to maintain the normal operation of the system. The third safety defensive line aims at the accident state of the electrochemical energy storage station, which carries out accident characteristic analysis and risk control and implements joint contingency plans to prevent the collapse of the electrochemical energy storage station and human casualties. The three safety defensive lines can realize the active prevention and control of safety risks and accidents of electrochemical energy storage station, providing a new idea for the safety design of energy storage stations. |
