Problems solved by technology

[0002] At present, most of the long-term forecasting methods for reservoir inflow are mathematical statistical methods, and a few of them also use astronomical indicators, but most of them use a single indicator, which has not formed a systematic application, and the accuracy is not high.

Embodiment Construction

[0013] The incoming water of the reservoir is greatly affected by astronomical factors, especially by the sun and the moon. Due to the different geographical locations of the reservoirs, the effects of astronomical factors are also different; if we analyze the correlation between the reservoirs at different geographical latitudes, the declination angle of the moon, and the relative number of sunspots, we will find that there are low latitudes in the same year. The phenomenon of dry reservoirs and high-latitude reservoirs, or vice versa, reflects the astronomical distribution effect of macroscopic water.

[0014] In order to establish a high-precision long-term forecast model of reservoir inflow, it is necessary to start with astronomical factors, analyze the influence of astronomical factors on reservoir inflow, answer the range of astronomical factors that have a significant impact, what impact effects, and answer multiple astronomical factors coupling effects.

Abstract

The present application discloses an astronomical factor identification method which can visually display the influence of the astronomical factor on the water of a reservoir in the past year, find out the rule of the influence of the astronomical factor on the water of the reservoir in the past year, and provide a basis for constructing a long-term forecast model of the water of the reservoir based on the astronomical factor, and thereby effectively improve the comprehensive utilization benefit of the reservoir. The method comprises the following steps: (1) splitting the annual water series of the reservoir: water statistics of the reservoir over the years and qualitative classification; formulating astronomical factor statistics table of reservoir incoming water; Reservoir water series splitting in recent years; (2) drawing the astronomical cause analysis chart of reservoir water in recent years, which includes the sunspot influence analysis chart of reservoir water in recent years,the declination angle influence analysis chart of reservoir water and moon in recent years, and the astronomical cause analysis chart of reservoir water in recent years; (3) the astronomical origin analysis of the reservoir water in recent years, including the influence analysis of sunspot relative number, the influence analysis of lunar declination angle, and the astronomical origin analysis.

Description

technical field [0001] The invention relates to the technical field of long-term hydrological forecasting, in particular to a method for identifying astronomical factors that affect the annual water of a reservoir. Background technique [0002] At present, most of the long-term forecasting methods for reservoir inflows are mathematical statistical methods, and a few also use astronomical indicators, but most of them use a single indicator, which has not been systematically applied and the accuracy is not high. Contents of the invention [0003] In order to overcome the defects of the prior art, the technical problem to be solved in the present invention is to provide a method for identifying astronomical factors that affect the annual water of a reservoir, which can visually show that the annual water of a reservoir is affected by astronomical factors, and find out the influence of astronomical factors on the incoming water of a reservoir. The law of influence provides the...
