Designing method of power analysis value model of riverbed type workshop of hydropower station

Abstract

The invention discloses a designing method of a power analysis value model of a riverbed type workshop of a hydropower station, and belongs to the field of water conservancy and hydropower. According to the invention, consistency and standardization of the design of the riverbed type workshop model of the hydropower station can be achieved and design period can be simultaneously shortened. The method comprises following steps of step 1, constructing a three-dimensional structure model of the riverbed type workshop of the hydropower station; step 2, dividing grids; step 3, setting the type of each grid unit; step 4, setting material attributes; step 5, setting connection forms of different types of grid units; step 6, setting a boundary condition; and step 7, simulating water quality. In this way, the method can be widely applicable to design of each finite element power analysis-based power analysis value model of the riverbed type workshop of the hydropower station, and design standardization for standardizing this type of model is facilitated.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a design method for a dynamic analysis numerical model of a river bed type powerhouse of a hydropower station. Background technique [0002] In the northwest and southwest of my country, the mountainous rivers have large longitudinal slopes, which are suitable for the development of hydropower resources; hydropower is currently the most widely used clean renewable energy in the world. In order to make efficient use of water energy resources, currently planned or under construction power stations tend to be huge; the single-unit capacity of hydroelectric generating units is getting larger and higher, and the operating water head is getting higher and higher. The powerhouse of a hydropower station is the core area of ​​the hub layout of the power station. The structure of the powerhouse is not only a complex of hydraulic buildings and electromec...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: the design method of the current numerical model of the dynamic analysis of the riverbed powerhouse of a hydropower station designed based on the finite element dynamic analysis does not have a unified reference design method and standard, and there is no unified reference design method and standard in the existing powerhouse model design method. Reasonable boundary conditions can be accurately set and the water bodies on the upstream and downstream sides of the powerhouse cannot be simulated effectively, which leads to inaccurate analysis results. The present invention provides a numerical model that can realize the dynamic analysis of the riverbed powerhouse of the hydropower station Consistency and standardization of design, as well as improving the accuracy of analysis results and shortening the design cycle, the numerical model design method for dynamic analysis of river bed type powerhouses
