Problems solved by technology

[0003] However, most of the existing construction diversion scheme decision-making techniques focus on the selection of initial diversion standards for hydropower stations under construction, which cannot take into account the interests and preferences of upstream hydropower stations, and it is difficult to achieve the coordination of the interests of all parties involved in river basin development and the improvement of overall benefits

Embodiment approach

[0075] Taking the implementation of the present invention in the development of cascade hydropower projects in a certain watershed as an example, a reservoir A has been built in a certain watershed, which is a comprehensive application hydropower project mainly for power generation and flood control. At present, cascaded hydropower project B located downstream of reservoir A is being planned and constructed. Its initial diversion method is planned to adopt the annual water retaining standard of the soil-rock cofferdam and the method of tunnel discharge. According to the relevant regulations, the diversion structure is For level 3 temporary buildings, after comprehensive analysis, the design flood standard corresponds to a return period of 20 to 50 years. According to the geography and hydrological characteristics of the basin, the main flood season is mainly when the upstream reservoir A encounters floods. There is cultivated land in the reservoir area, and the allowable inunda...

Abstract

The invention relates to construction diversion scheme decision-making technologies of hydraulic and hydroelectric engineering, and provides a decision-making method for a construction diversion scheme considering flow discharge control of an upstream hydropower station for tackling defects that effects of companies in the basin in overall management decision making are not considered in traditional technologies. The method comprises the following steps of a, selecting decision-making indexes of the construction diversion scheme considering flow discharge control of the upstream hydropower station and carrying out calculation and analysis; b, recommending construction diversion schemes by upstream and downstream hydropower stations; c, giving weight vectors to the indexes according to respective preferences and establishing respective scheme evaluation functions by the upstream and downstream hydropower stations; d, based on negotiation countermeasures and optimization theories, adopting a two-stage planning method for obtaining optimal solutions in the perfect condition; e, carrying out normalization of the decision-making index matrixes and the optimal solutions in the perfect condition of the upstream and downstream hydropower stations; and f, giving weight vectors to objects considering overall benefits of the basin according to experts in related fields, and adopting a mode recognition theory method to solve the optimal construction diversion scheme.

Description

technical field [0001] The invention relates to a decision-making technology for a construction diversion scheme of a water conservancy and hydropower project, in particular to a decision-making method for a construction diversion scheme considering discharge control of an upstream hydropower station. Background technique [0002] In recent years, with the continuous advancement of the construction of cascade hydropower stations in many river basins in Southwest China, such as the Yalong River Basin, Dadu River Basin, and Jinsha River Basin, more and more hydropower projects are facing the impact of discharge control from upstream hydropower stations. However, in this case, the construction diversion scheme involves different stakeholders (namely, the upstream hydropower station and the downstream hydropower station), the information of different stakeholders is asymmetric, and the value orientation and decision-making preference are different. For example, the upstream hydr...
