摘 要:结合乌弄龙水电站的输水发电系统过渡过程,保证电站运行过程中调压室不发生漏空及漫顶事故,对调压室的体型进行了优化,对比分析了调压室面积、阻抗孔面积对引水发电系统水力过渡过程的影响。结论表明,随着阻抗孔面积的增加,尾水进口最小压力逐渐增加,调压室最低涌浪逐渐减小,调压室最高涌浪逐渐增加。随着调压室面积的增加,调压室最低涌浪逐渐上升,调压室最高涌浪逐渐降低,从而优化了本电站调压室的体型参数,满足了电站安全运行的要求。Combined with black dragon hydropower station water generating system transition process,ensure that pow⁃er surge will not occur during the operation of air leakage and overflow accident,size of surge chamber is optimized,the contrast analysis of the surge chamber area,impedance hole area to the influence of the transient process of water diversion system,results indicate that with the increase of impedance hole area,tail water import minimum pressure in⁃crease gradually,the lowest surge in the surge chamber decreases gradually,while the highest surge in the surge cham⁃ber increases gradually.With the increase of the area of the surge chamber,the lowest surge wave of the surge cham⁃ber increases gradually,while the highest surge wave of the surge chamber decreases gradually,so as to optimize the size parameters of the surge chamber and meet the requirements of the safe operation of the power station.
