Solar energy resource analysis and assessment method for photovoltaic power station design

Abstract

The present invention discloses a solar energy resource analysis and assessment method for photovoltaic power station design. A self-built light resource database based on a solar energy resource area is used for assessment, automatically completes all calculation work required by the solar energy resource analysis and assessment and automatically generates finished products; and based on the solar energy resource area accomplishment construction, an object area is subjected to partition according to the condition of an insolation station, each partition takes an internal insolation station as a reference weather station, all the areas except the insolation station employ the uniform reckoning formula, and the solar energy resource data of the insolation station is employed to automatically calculate the total radiant quantity of the sun. The solar energy resource analysis and assessment method for photovoltaic power station design is suitable for development of the photovoltaic power station design at an object area, collects and arranges the light recourse data through the light resource database built based on the solar energy resource accomplishment construction, completes the solar energy resource analysis and assessment and outputs the accomplishment so as to improve the work efficiency, reduce the error probability and improve the quality of the finished products.
