摘要
在大花水水电站过渡过程计算中,考虑到调压室直径、阻抗孔面积、阻抗系数等因素对水击压力的影响,分别用常规方法和考虑各种影响两种方法计算水击压力,提出了调压室对水击波不完全反射时的水击压力计算方法;并对两种方法的计算结果进行了对比,说明对阻抗式调压室按不完全反射水击波的水击压力计算方法计算出的水击压力更符合实际情况。
In the calculation of the transition process of Dahuashui Hydropower Plant, the paper calculated the water hammer pressure using two different methods to consider the influences of surge tank diameter, the hole and the coefficient of resistance. The two methods are conventional one and one considering all the influences, respectively. The paper brought forward a method of water hammer wave calculation with water reflecting incompletely of surge tank. The results indicated that the method of water hammer wave calculation with water reflecting incompletely accords with the actual conditions, compared with the method of water hammer calculation with water hammer wave reflecting completely for throttled surge tank.
