Method for increasing regulation storage and generating compensation benefits of high-dam leading reservoir

Abstract

The invention discloses a method for increasing regulation storage and generating compensation benefits of a high-dam leading reservoir. According to the method, a water turbine and difference of dynamic water generating of a water diversion system and a safe waterhead of still water retaining are adopted, a new limit dead water level is set below an existing dead water level of the reservoir, the regulation storage and the available water supply in the dry season can be increased, and the generating benefits of all downstream hydropower stations are increased accordingly; a hydraulic turbine set and a corresponding water diversion generating system which are suitable for operation of the limit dead water level and the original dead water level are additionally arranged, and the generating benefits of the hydropower stations are increased; the newly increased available water supply in the dry season enables other weepage water channels of the hydropower stations to discharge; after the limit dead water level is additionally set, the function of emptying the upper layer water storage is achieved as well. According to the method, the direct water supply generating benefits are remarkable, national energy security is facilitated, and the grid electric energy quality is promoted beneficially; meanwhile, the method has the advantages that the proportion of utilizing the clean energy and renewable energy sources is increased, the utilization efficiency of water resources is improved, and environment protection is promoted.

Description

technical field [0001] The invention belongs to the technical field of combined matching of hydropower stations, and in particular relates to a method for increasing and adjusting storage capacity and generating compensation benefits of a high-dam leading reservoir. Background technique [0002] Hydropower is an important conventional, clean, and renewable energy. Cascade hydropower operates flexibly in the grid, with high reliability and low operating costs. In the cascade development of river hydropower, the leading reservoir is the most critical part, which directly affects the performance, layout, scale and economic benefits of the entire river hydropower, and is also an important part of coordinating inundation, social environment and ecological environment. [0003] With the development and progress of society, the relationship between hydropower construction and land acquisition, ecological environment, and social impact has been highly concerned and increasingly prom...

Problems solved by technology

[0005] Under the influence of the above-mentioned factors, in order to reduce the impact of the reservoir on the society and the environment, firstly, the scale of the storage capacity is limited, and at the same time, the dam height required for the unit storage capacity and the total project investment are increased; the economic indicators of the corresponding hydropower stations and cascades will also increase. lower than before

[0006] For the leading reservoir of a high-head dam, the original conventional design is limited by the metal structure of the water intake of the hub, the stability and safety of the turbine operation, the dead water level of the reservoir is high, and most of the reservoir capacity cannot be used, and the benefits of the corresponding reservoir will be reduced. can't get better performance
