This thesis aims at the construction, simulation and verification of disaster-prevention solar photovoltaic power generation system. Its purpose is to build a solar photovoltaic power generation system that can continue to provide electricity when power is interrupted by irresistible factors or disasters. At ordinary times, when the battery is fully charged, the surplus power will be fed into the city electricity, and when the sunshine is low, it will still be supplied by the city electricity at night, so as to achieve the power supply mode of parallel connection of the city electricity; However, when a disaster occurs and the commercial power is cut off, the important load can be powered by the storage battery immediately, so as to achieve the function of emergency disaster prevention. In this study, PVsyst simulation software is used to simulate and analyze, including the planning, design and monitoring system construction of disaster-prevention solar photovoltaic power generation system to verify the feasibility of the whole system.
