Embodiment 1

[0038] Such as figure 1 As shown, a solar resource analysis and evaluation method for photovoltaic power station design, the method is divided into three stages: solar resource zoning, solar resource database construction, and solar resource analysis and evaluation, as follows:

[0039] (1) Solar resource zoning

[0040] Carry out solar energy resource zoning work for a large number of target areas (one province or multiple adjacent provinces) where photovoltaic power station design is carried out;

[0041] Determine the number and location of insolation stations in the target area, and divide the target area into multiple partitions according to geographical conditions (including distance, latitude, altitude, topography) and climate characteristics combined with existing data, and each partition corresponds to an insolation station. The insolation station in the zone is the reference insolation station for the photovoltaic power station project in the zone;

[0042] (2) Opt...

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.

Description

technical field [0001] The invention relates to a solar energy resource analysis and evaluation method, in particular to a solar energy resource analysis and evaluation method for photovoltaic power station design, belonging to the field of solar energy resource analysis and evaluation. Background technique [0002] my country's solar energy resources are very rich. In recent years, my country's photovoltaic industry has developed rapidly. The construction of photovoltaic power stations is the most effective way to use solar energy on a large scale. [0003] In the feasibility study stage of photovoltaic power plant design, it is necessary to carry out solar energy resource analysis and evaluation, explain the solar energy resources in the area where the project is located, and provide input data for the calculation of power generation of the power plant. [0004] When analyzing and evaluating solar energy resources, it is necessary to select a meteorological station with lo...
