摘要
针对四川省广元市昭化镇境内的白龙江昭化水电站,使用一维流体分析软件Flowmaster对水电站技术供水系统的稳态与暂态进行分析研究。通过模拟分析得到昭化水电站技术供水系统各元件在稳态与暂态情况下的参数,在此基础上选择最合理的方案对水电站运行进行优化。稳态过程分析表明昭化水电站技术供水泵选择不合理;暂态过程2种方案分析表明停泵后关闭电动阀是最为安全的,但要注意关阀时间和操作方式,采用两段关闭的方式更加安全。
The steady-state and transient state of the technical water supply system of Zhaohua Hydropower Station in Bailong River in Zhaohua Town,Guangyuan City,Sichuan Province is analyzed by using one-dimensional fluid analysis software Flowmaster.The parameters of each component of the technical water supply system under steady-state and transient conditions are obtained by simulation analysis respectively,and on this basis,the most reasonable scheme is selected to optimize the operation of hydropower station.The steady-state process analysis shows that the selection of technical water supply pump is unreasonable.The analyses of three kinds of transient processes show that it is safest to close the electric valve after stopping the pump,but it is necessary to pay attention to valve closing time and operation mode,and the two-stage closing mode of electric valve is more secure.
