摘　　要：以庙林水电站为例,通过编制阻抗式调压室数值基本方程,试算阻抗式调压室在最不利组合工况下的水位波动和底板压差值,将试算结果数值与水力模型试验结果进行分析对比,结果表明对水力边界条件相似的引水式电站,只要选择合适的阻抗系数,数值计算结果是可行的。Miaolin Hydropower Station is adopted as an example,water level fluctuation and bottom board pressure difference values of impedance surge chamber under the most unfavorable combination conditions are calculated through formulating impedance surge chamber numerical fundamental equation.The trial calculation result values and hydraulic model test results are analyzed and compared.The result shows that as long as suitable impedance coefficient be selected in water diversion type power station with similar hydraulic boundary conditions,the results of numerical calculation are feasible.
