摘　　要：通过已建电站的统计规律及相关资料,开展调压室阻抗孔口尺寸对蜗壳压力、尾水管压力、调压室水位等参数的敏感性分析,得出阻抗孔尺寸对水力调保性能的影响规律,为后续调压室设计提供数据支撑和实践依据。Through the analysis of the statistical law and related data of the built power station,describes the effect of the impedance surge chamber’s impedance hole size for the volute pressure change and the draft pressure change draft tube and the water level change in surge chamber,obtained the effects of different impedance hole sizes for the pressure regulation and protection performance,which provides data support and practical basis for the subsequent design of the surge chamber.
