Abstract

The application provides a hydropower characteristic curve correction method and device, which relate to the technical field of hydropower dispatching. The method includes: obtaining at least one set of hydropower parameters of the hydropower station within a preset historical time period; performing curve fitting according to each set of hydropower parameters to obtain a fitting curve corresponding to each set of hydropower parameters; The fitting curve is corrected to obtain at least one target hydropower characteristic curve of the hydropower station. By obtaining a large number of historical hydropower parameters to construct sample data, the sample data is more reliable, and the fitting curve obtained according to the hydropower parameters is more instructive. In addition, by correcting the obtained fitting curve, the accuracy of the fitting curve is improved to a certain extent, so that the power generation data calculated according to the revised fitting curve is more accurate, and the accuracy of hydropower dispatching is effectively improved. Efficient and economical operation provides accurate and reliable basic data support.

Description

technical field [0001] The invention relates to the technical field of hydropower dispatching, in particular to a method and device for correcting a hydropower characteristic curve. Background technique [0002] In the past 20 years, China has led the rapid development of hydropower in the world. In the southwestern region of my country, a group of super-large river basins with hydropower installed capacity exceeding 10 million kilowatts have been formed. Hydropower group, my country has entered the era of large hydropower system dispatching and operation. The discharge flow-tail water level, water head-water consumption rate characteristic curves are important basic data for determining the working head of a hydropower station, calculating the power generation capacity, and optimizing hydropower dispatching. After the power station is put into operation, with the changes in the downstream river environment and the operating performance of the unit, the deviation of the desi...
