A method and system for health status assessment of a photovoltaic power station

Abstract

The invention provides a method and a system for evaluating the health status of a photovoltaic power station. The method comprises the following steps: calculating the standard power output of a unitinstalled unit of the photovoltaic power station according to the natural environment of the region where the photovoltaic power station is located; and calculating the standard power output of the unit installed unit of the unit installed unit of the photovoltaic power station; acquiring Actual power generation per unit installed capacity per day of the photovoltaic power station; According to the relationship between the daily installed power output of photovoltaic power station and its standard power output, evulating the health status of photovoltaic power station. The invention providesa method for evaluating the health state of a photovoltaic power station, which calculates a standard power generation quantity of the photovoltaic power station installed unit according to the natural environment of the area where the photovoltaic power station is located, and evaluates the health state of the photovoltaic power station according to the relationship between the standard power generation quantity and the actual power generation quantity of the photovoltaic power station. The technical proposal provide by the invention adopts less data quantity, the calculation process is simple and can solve the problems of complex calculation process and low work efficiency when evaluating the health status of a large number of connected photovoltaic pow stations.
