摘要
为研究LTQN水电站发电引水系统调保是否满足设计要求,通过无调保措施下的过渡过程数值计算、设置减压阀后机组与减压阀启闭规律优化及水力干扰分析,选择减压阀较优的阀径组合方案,并提出电站运行期各工况减压阀联动启闭时间以及导叶启闭时间.该工程选择设置减压阀做为发电引水系统调保措施是经济合理的,本次水力过渡过程分析成果为发电引水系统设计和电站安全运行提供理论依据.
In order to study whether the regulation and maintenance of the power generation and diversion system of LTQN hydropower station meet the design requirements,through numerical calculation of the transition process without regulation and maintenance measures,optimization of the opening and closing laws of the unit and the pressure reducing valve after setting the pressure reducing valve,and hydraulic interference analysis,the optimal valve diameter combination scheme of the pressure reducing valve is selected,and the linkage opening and closing time of the pressure reducing valve and the opening and closing time of the guide vane under various operating conditions of the power station are proposed.The selection of a pressure reducing valve as a maintenance measure for the power generation and diversion system in this project is economically reasonable.The analysis results of this hydraulic transition process provide a theoretical basis for the design of the power generation and diversion system and the safe operation of the power station.
