Mixed arrangement structure of pumped storage unit and conventional unit of pumped storage power station
The invention discloses a mixed arrangement structure of a pumped storage unit and a conventional unit of a pumped storage power station, relates to the field of water conservancy and hydropower engineering, and solves the problems of large engineering amount and high investment caused by independent arrangement of water diversion systems for the pumped storage unit and the conventional unit of an existing hydropower station. According to the technical scheme, the mixed arrangement structure of the pumped storage unit and the conventional unit of the pumping storage power station comprises a pumping and storage unit and a conventional unit, the conventional unit is provided with a water diversion system and a tail water system, the water diversion system comprises a water diversion pipeline, the water diversion pipeline is connected with a water conveying branch pipe, and the other end of the water conveying branch pipe is connected to the pumping and storage unit; the pumping and storage unit is provided with a tail water system, the tail end of the tail water system of the pumped storage unit is located in the downstream reservoir and is lower than the dead water level of the downstream reservoir. The pumping and storage unit conducts water diversion through the water conveying branch pipe, a water diversion system of a conventional unit can be shared, and therefore the work amount is reduced, and investment is saved. The structure is suitable for transforming a conventional hydropower station into a normal storage combined power station, and the energy storage effect of the hydropower station is improved.
本发明公开了一种抽蓄电站抽蓄机组与常规机组混合布置结构，涉及水利水电工程领域，解决现有水电站抽蓄机组与常规机组独立设置引水系统所导致的工程量大、投资高的问题。本发明采用的技术方案是：抽蓄电站抽蓄机组与常规机组混合布置结构，包括抽蓄机组与常规机组，常规机组配备引水系统和尾水系统，引水系统包括引水管道，引水管道上连接输水支管，输水支管的另一端连接至抽蓄机组，抽蓄机组配备尾水系统，抽蓄机组的尾水系统末端位于下游水库且低于下游水库的死水位。抽蓄机组通过输水支管进行引水，可以共用常规机组的引水系统，从而减少工程量并节省投资。本发明适用于将常规水电站改造成常蓄结合电站，提高水电站的储能作用。
