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。

Abstract：Combined with black dragon hydropower station water generating system transition process，ensure that power 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 increase gradually，the lowest surge in the surge chamber decreases gradually，while the highest surge in the surge chamber increases gradually.With the increase of the area of the surge chamber，the lowest surge wave of the surge chamber 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.

水電站调压室涉及的主要体型参数有：阻抗孔或连接管的面积（或直径）、调压室面积（或直径）。尾水调压室反射水锤波的性能影响因素主要是阻抗孔（连接管）面积;而下游调压室最高、最低水位和工程量的影响因素除了阻抗孔（连接管）面积外，还包括调压室面积。调压室的顶底板高程是影响其漏空的因素，所以这些参数的合理取值非常重要。而调压室阻抗孔口参数的优化，在压力满足要求下，选取较小面积，以减小涌浪幅度和调压室体积，工程量也会减少[1-3]。本文主要针对工况D8、D12、Z1、Z3、Z5对调压室的体型参数进行了优化计算分析。
