Reservoir scheduling early warning method based on meteorological numerical forecasting

Abstract

The invention discloses a reservoir scheduling early warning method based on meteorological numerical forecasting, which comprises the following steps: calculating the interceptable water storage capacity in a basin according to the acquired hydrological information of each hydropower station in the basin of a target reservoir, and correcting the early-stage influence rainfall Pa according to theinterceptable water storage capacity; determining a runoff coefficient rho according to the hydrological information and the meteorological information, calculating the capacity storage purified wateramount and the capacity storage precipitation amount of the reservoir based on the runoff coefficient rho, and carrying out capacity storage precipitation amount early warning; according to the hydrological information, the drainage basin information, the early-stage influence rainfall Pa, the runoff coefficient rho and the meteorological information, short-term period runoff prediction of the reservoir is conducted, and the medium-term and long-term end water level is calculated; and determining a flood prevention early warning level and a drought resistance early warning level according tothe hydrological information, the meteorological information and the end-of-period water level information, and performing reservoir scheduling. The reservoir scheduling early warning method has the advantages that the reservoir scheduling risk early warning capacity is improved, and life and property safety of reservoir dams and downstream people is ensured.

AI Technical Summary

Benefits of technology

The technical effect described by this patented technology allows planning and controlling the allocation of resources within specific areas during emergency situations such as fires or heavy rain without causing damage or injury. This helps prevent overloading buildings with excessive energy consumption while ensuring safe use of these facilities.

Problems solved by technology

The technical problem addressed in this patents relates to improving the allocation efficiency and planning capabilities of hydroelectric plants (HES) while ensuring proper monitoring and controllability over various factors such as water levels or resource availabilities. Current methods rely heavily upon manual input from field workers who manually determine optimal placement locations within specific areas around the facility's location. This limits their ability to optimize energy production and provide better economic benefit options.
