Abstract

The invention provides a hydropower station dynamic property computer-assisted testing method. The method includes the following steps of firstly, obtaining fuzzy dynamic characteristic data from an operation comprehensive characteristic curve, and obtaining a flow output dynamic characteristic equation from a hydropower station dynamic characteristic curve; secondly, processing the fuzzy dynamic characteristic data, wherein drawing data, measured under different water heads, on grid square paper, the longitudinal axis of the grid square paper is set to represent the flow of a water turbine, the horizontal axis of the grid square paper is set to represent the power of the water turbine, and then the dynamic characteristic, under the average water head, of the water turbine is obtained; thirdly, drawing the hydropower station dynamic characteristic curve with the assistance of the computer, and obtaining the hydropower station dynamic characteristic curve. For the operation comprehensive characteristic curve of the water turbine, dynamic characteristic data are obtained, data processing is conducted, and the hydropower station dynamic characteristic testing is achieved.

Description

technical field [0001] The invention relates to the field of economic operation of a hydropower station, in particular to a computer-aided testing method for the dynamic characteristic curve of a hydropower station. Background technique [0002] The dynamic characteristic of hydropower station is an important content in the economic operation of hydropower station. The dynamic characteristic curve of a hydropower station is used to represent the energy change and loss characteristics of a hydropower station when water energy is converted into electric energy. The dynamic characteristic curve of the hydropower station can be used to study the hydraulic performance of the hydropower station at the moment, and also provide a basis for formulating the optimal distribution of active load of the hydropower station. [0003] At present, the equipment of rural hydropower stations is backward. Most of the hydropower stations have not done real machine tests. They only formulate the ...
