Hydropower-station flood optimization dispatching method taking gate operation rules into consideration

Abstract

The invention discloses a hydropower-station flood optimization dispatching method which takes gate operation rules into consideration. The method includes five steps: (1) structural description of the gate operation rules, which solves an expression problem of the complex gate operation rules; (2) instantiation of the gate operation rules, which solves a problem of how to use the structural-body examples of the gate operation rules to describe specific hydropower-station gate operation rules; (3) optimization generation of a gate opening combination number sequence, which solves a problem of coupling of the gate operation rules and traditional hydropower-station flood optimization dispatching methods; (4) optimization adjustment of the gate opening combination number sequence, which solves problems that in a flood dispatching process, during specific periods, water level exceeds the limit and at the end of a dispatching period, deviation exists between the water level and a target water level; (5) generation of a gate operation plan, which solves a problem of generating the gate operation plan dynamically according to the gate opening combination number sequence. The hydropower-station flood optimization dispatching method which takes the gate operation rules into consideration improves prediction accuracy of a later-period flood-discharge flow process and improves the rapid response capability of a flood prevention decision of a hydropower station.

Description

technical field [0001] The invention relates to a flood optimization dispatching method, in particular to a hydropower station flood optimization dispatching method considering gate operation rules. Background technique [0002] The traditional flood optimization dispatching method for hydropower stations regards all gates as a dispatching object, only considers the overall discharge capacity of all gates, and does not consider gate operating rules such as the allowable opening degree, opening sequence, and opening degree combination of each gate, and can only calculate The optimized total discharge flow process line of the hydropower gate group as a whole cannot automatically formulate the optimal operation plan for each gate. In the actual operation link, the dispatcher needs to manually formulate the operation plan of each gate according to the optimized total flood discharge flow process line. This method is difficult to meet the business needs of fine scheduling and re...

Problems solved by technology

[0017] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a hydropower station flood optimization dispatching method that considers gate operation rules, which solves the problem of serious deviation between the actual execution link and the planning link of the traditional method, and improves the hydropower station’s optimal flood discharge flow process line. The actual guiding role of the dispatcher reduces the work intensity and error probability of the dispatcher, and at the same time, assists the dispatcher to more accurately study and judge the change of the flood control situation in the later period
