A flood control scheduling method for cascade reservoirs in the upper reaches of the Yellow River considering early warning

Abstract

The invention discloses a Yellow River upstream cascade reservoir flood control scheduling method considering early warning. The Yellow River upstream cascade reservoir flood control scheduling methodis characterized by comprising the following steps that 1, a Yellow River upstream cascade reservoir flood control early-warning system is established; 2, a cascade reservoir flood control schedulingmodel based on the early-warning system established in the step 1 is established; 3, optimizing calculation is conducted on the flood control scheduling model established in the step 2, and a scheduling result and an optimal early-warning decision are output. The Yellow River upstream cascade reservoir flood control scheduling method considering early warning combines with the cascade reservoir united flood control scheduling model to assess the flood control risk degrees of a reservoir and a downstream protective object and determine the comprehensive risk degree and flood control early-warning level, future time period prediction information is utilized to formulate a reasonable and effective early-warning strategy, and the flood control early-warning system suitable for a Yellow Riverupstream cascade reservoir group is established.

Description

technical field [0001] The invention belongs to the technical field of flood control scheduling methods, and in particular relates to a flood control scheduling method for cascaded reservoirs in the upper reaches of the Yellow River considering early warning. Background technique [0002] Flood is one of the major natural disasters that threaten the safety of human life and social stability. In recent years, extreme flood events have occurred frequently and serious disasters have occurred. The issue of flood control and disaster reduction has received close attention. Reservoirs are an important engineering measure to resist flood disasters and have played an important role in flood control and disaster reduction. With the improvement of hydrological monitoring and reservoir operation and management, the thinking of water control in the new era has changed. While engineering construction, we should strengthen Use of non-engineering measures. Non-engineering measures for flo...

Problems solved by technology

[0005] The purpose of the present invention is to provide a flood control scheduling method for cascade reservoirs in the upper reaches of the Yellow River that considers early warning, which solves the problem in the prior art that the complex water system flood control scheduling and flood control early warning are separated from each other, and risk analysis is difficult to apply to flood control scheduling.
