Abstract: With the gradual improvement of the coupling between new energy technology and oil and gas field development business，a number of distributed new energy application projects with "photovoltaic power system+oil well production" and "photovoltaic power system + gas field gathering and transportation" as the main technical route have begun to enter the stage of construction and putting in- to production. In order to solve the problem of continuous operation of remote isolated photovoltaic grid in oil and gas fields and sup- press the fluctuation of grid connected photovoltaic power generation，well-proven electrochemical energy storage technologies are of- ten used as a supporting means on site. However，the safety of electrochemical energy storage has always been the main challenge for its popularization and application，which brings great risks to the production sites of oil and gas fields. In this paper，the installation safety distance of typical electrochemical energy storage system under different conditions is analyzed first，based on which a layout for optical energy storage is recommended. After that，the risk matrix analysis method is used to evaluate all risks related to the operation of photo- voltaic energy storage projects in oil and gas fields，and the risk levels of hidden hazard events are rated. Finally，key design points and safety management strategies adaptable to the energy storage devices of distributed photovoltaic system in oil and gas fields are devel- oped，which provides guidance for the safety configuration and accident prevention of distributed photovoltaic energy storage.

Key words: distributed photovoltaic power system, electrochemical energy storage, thermal runaway analysis, risk matrix analysis, oil , and gas field development

摘要： 随着新能源技术与油气田开发业务耦合度逐渐提升，以“光伏+油井开采”和“光伏+气田集输”为主要技术路线的一批分布式新能源应用项目开始进入施工和投产阶段。为解决油气田偏远光伏孤网连续运行和平抑并网光伏发电量波动问题，现场常选用技术成熟的电化学储能技术作为配套手段。但是电化学储能的安全问题一直是其推广应用所面临的主要挑战，给油气田生产现场带来较大风险。首先分析了典型的电化学储能系统在不同条件下的安装安全距离，进而得出推荐的光储布局方式；其次运用风险矩阵分析法对油气田光储项目运行的各类风险进行评估，给出了隐患事件的风险等级；最后形成了一套适用于油气田分布式光伏系统储能装置的设计要点和安全管理策略，为分布式光伏储能的安全配置及事故预防提供了指导。
