Method for fast calculating electric energy production of hydropower station

Abstract

The invention provides a method for fast calculating the electric energy production of a hydropower station. The method mainly comprises the following steps of: selecting a historical runoff series; determining a reservoir operation mode of the hydropower station; and building a relationship between the effective runoff and the electric energy production to calculate the electric energy protection of the hydropower station. The method has the advantages that an effective runoff index is provided for the first time; after one-time modeling, the effective runoff index can be directly obtained through calculation of runoffs at different periods, and the use of other parameters is not needed; according to the electric energy production-effective runoff mutual conversion relationship provided by the invention, in the given reservoir operation mode of the hydropower station, the corresponding annual electric energy production can be obtained through simple calculation or table look-up after the inflow water condition is converted into the effective runoff; the annual electric energy production in the given reservoir operation mode can be simply and fast calculated; and the application scenes are wide.

Description

technical field [0001] The invention relates to a method for calculating the generating capacity of a hydropower station. Background technique [0002] Power generation is an important index to evaluate the economic benefits of hydropower stations, and runoff is one of the important factors affecting power generation. Under the same reservoir operation mode, there is a positive correlation between annual power generation and annual runoff, but at the same time, it is affected by the process of intra-year runoff distribution, resulting in a multi-valued correspondence between annual power generation and annual runoff. In the case of the same annual runoff, the annual power generation may vary greatly, and even the phenomenon that the annual runoff is relatively large and the power generation is small. The main reason is that when the runoff is relatively dry, the hydropower units cannot be fully generated and the runoff is relatively abundant. When the power generation head ...

AI Technical Summary

Problems solved by technology

Therefore, the power generation cannot be calculated quickly and accurately only by using the annual runoff, and the relationship between the annual runoff distribution process and power generation cannot be directly described

The calculation methods currently used are complex, heavy workload, and low efficiency, and professional calculation software systems must be used, and the application scenarios are limited
