Embodiment Construction

[0104] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0105] A method for calculating the power generation of a photovoltaic power station based on photometric data, the calculation steps of the present invention are:

[0106] 1) Characteristics of optical resource data

[0107] In the preliminary work of the photovoltaic power station, it is required to set up a solar radiation observation station. After completing the time-series data collection of the total solar radiation and temperature measured by the minute, the long-term data sequence is adjusted according to the historical data of the local weather station; The data source of the inventive method is to use the radiation data and ambient temperature data of the photovoltaic power station every minute after correction;

[0108] 2) Sun azimuth calculation

[0109] According to the theory of spherical astronomy, the celest...

Abstract

The invention provides a method for calculating photovoltaic power station generating capacity based on light metering data. The method comprises the steps that the generated power of a photovoltaic power station at any time in the whole year is calculated according to radiation data and the environment temperature data minute by minute in the whole year after correction; the generating capacity day by day, the generating capacity month by month and the generating capacity in the whole year of the planned construction photovoltaic power station are calculated. The method achieves calculation of the generating capacity hour by hour, the generating capacity day by day, the generating capacity month by month and the generating capacity in the whole year of the photovoltaic power station. The method has been applied to early stage construction of a plurality of photovoltaic power stations in China, and a foundation is laid for generating capacity and technical and economic assessment in the preliminary work of the photovoltaic power station. Through analysis of the generating capacity characteristics of the photovoltaic power station, a theoretical basis can further be provided for component inclination angle optimization, component distance design, station post-assessment and the like of the photovoltaic power station.

Description

technical field [0001] The invention relates to a method for calculating the power generation of a photovoltaic power station, which combines the corrected annual radiation data and ambient temperature data of the photovoltaic power station every minute; realizes the calculation of the power generation of the photovoltaic power station at each time and period of the year . Background technique [0002] Currently, RETScreen and PVSYST software are mostly used to calculate the power generation of photovoltaic power plants. Since the above software does not have the function of calculating the generated power of the photovoltaic power station at any time; and its algorithm is encapsulated, and does not provide the interface of the corresponding function. Therefore, when it is necessary to calculate the generating power and generating capacity of a photovoltaic power station at a certain moment; when calculating the generating capacity of a photovoltaic power station on a certa...
