Abstract: The development of distributed photovoltaic power generation system promotes the development of social economy. The fire prevention problems in the exploitation design, construction and maintenance stage have also attracted more and more attention. This paper takes a typical distributed photovoltaic power generation system fire accident as the research object, focuses on the working principle, system composition, operation and maintenance management mode to deeply analyze the ignition law of such fires, restores the evolution process of fires, and summarizes the basic methods and investigation focuses of distributed photovoltaic power generation system fire investigation. At the same time, from the aspects of design, product selection, operation and maintenance management, technical measures and so on, the fire prevention and control of distributed photovoltaic power generation system is proposed.

Key words: distributed photovoltaic power generation system, fire investigation, fire prevention
