Local solar energy resource abundance evaluating system for design of photovoltaic power station

Abstract

The invention relates to a local solar energy resource abundance evaluating system for design of a photovoltaic power station, which can be widely applied to scientific research and engineering application in the fields related to solar energy. In the system, a data acquisition module is used for acquiring various indexes of four meteorological parameters from a meteorological observation system; an integrated operation module is used for operating and analyzing the acquired meteorological data by a representative meteorological year and month method; an evaluation and quantization value acquisition module is used for stacking annual daily total solar radiation data generated in the integrated operation module to acquire an evaluation and quantization value; and a solar energy resource evaluation module is used for comparing the quantization value with an evaluation system to acquire an abundance evaluation result of the solar energy resources. The system can be widely applicable to various areas and climate conditions, the generated annual daily solar radiation data have representativeness, the evaluation result is objective and reasonable, and the system can meet the requirements on design engineering application of the photovoltaic power station.

Description

technical field [0001] The invention belongs to a system in the technical field of photovoltaic power station design, in particular to a system for evaluating the richness of solar energy resources in a region used for photovoltaic power station design. Background technique [0002] Energy is the material basis for the existence and development of human society. According to the 2009 National Economic and Social Development Statistical Bulletin of the National Bureau of Statistics of China, the total energy consumption in 2009 was 3.10 billion tons of standard coal, an increase of 6.3% over the previous year. As the world's second largest energy consumer, China is facing the dual pressure of rapidly growing energy demand and increasingly serious environmental problems. Solar energy is a clean and renewable energy, which has been highly valued by our government. The annual solar radiation of more than 2 / 3 of my country's land area exceeds 6 billion joules per square meter, ...

Problems solved by technology

At present, domestic research in this area is still relatively small, and only a few regions have fitted some simple empirical formulas for solar radiation, and the scope of application of these formulas is limited by regions and climates.
