Embodiment Construction

[0062] Include the following steps:

[0063] (1) Forecasting of inflow runoff, the forecast period of inflow runoff includes long-term in years or months and mid-term in ten days, using the method of long-term inflow runoff forecasting for reservoir group supply and water transfer system based on transcendence probability to predict long-term inflow The runoff is forecasted on a rolling basis, while the medium-term inbound runoff forecast adopts the rolling forecast method of inbound runoff based on GFS rainfall information. The specific steps of inbound runoff forecasting are as follows:

[0064] (a) A method for forecasting long-term inflow runoff of reservoir group supply and water diversion systems based on transcendental probability. The specific steps are as follows:

[0065] ① Select the total amount of runoff that has occurred in the year as the predictor (Z j ), for the inflow runoff in the rest of the year (Q i ) qualitative forecast of the situation;

[0066] ② A...

Abstract

The invention relates to a real-time scheduling method for a reservoir group water supply and transfer system and belongs to the field of reservoir scheduling operation. The scheduling method comprises in-reservoir runoff forecasting and water demand forecasting, scheduling method and real-time correction. According to the characteristics of the reservoir group water supply and transfer system, an in-reservoir runoff forecasting method, an optimal scheduling modeling solving method, coupling and nesting modes in different time periods and system real-time scheduling specific flow are designed; and with the water demands of different users being taken into consideration, and under the precondition of guaranteeing water supply safety, water sources are allocated optimally, and maximizing of water supply benefits is realized.

Description

technical field [0001] The invention relates to the field of scheduling operation, in particular to a real-time scheduling method for reservoir group supply and water transfer systems. Background technique [0002] The uneven distribution of water resources and the unbalanced water demand of human society make inter-basin water transfer inevitable. At present, the cross-basin water transfer projects that have been planned or are being implemented include the South-to-North Water Diversion Project, the Central Jilin Water Diversion Project, and the River and Reservoir Water System in Liaoning Province. China Unicom Engineering, etc. In order to alleviate the contradiction between the supply and demand of water resources in North China and Northwest my country, the country has implemented a large-scale South-to-North Water Diversion Project; in order to alleviate the contradiction between supply and demand of water resources in the central part of Jilin Province, ensure the pe...
