| 摘 要： | 本文主要针对黄河拉西瓦、汉江毛坝关水电站工程,在物理模型试验资料的基础上,对水电站的水力过渡过程的仿真计算作了验证,验证计算方法和参数选择的合理性,并率定计算参数.得到调压室最高/最低涌浪水位、蜗壳及岔管断面最大/最小水锤压力、机组最大飞车转速以及它们的变化过程线.在钻根水电站和扎古录水电站的调保计算中,计算了引水隧洞、压力钢管最大/最小水压力包络线、小波动和水力干扰下的发电频率摆动机组稳定性分析等成果.采用Fluent软件模拟某瞬间调压室内的三维流场,动态地显示了调压室水位波动情况.

| Abstract: | The calculated transition process of a numerical model is verified by using test data of two physical models,one for Laxiwa hydropower station on Yellow River and another for Maobaguan on Han River,including the selection and calibration of the numerical model parameters and the calculation method.Comparisons between calculations and test data are made for the highest/lowest water levels in the surge chamber,penstock max./min.water hammer pressures in the volute and the bifurcated pipe,the largest unit spee... |
