摘要
本文根据李家峡水电站备用机组的尾水两相非恒定流问题,利用特征线差分方程进行数值计算.对上、下游水击压力及水轮机转速的稳定性进行了分析.给出了交界面波动的影响范围.
Based on the two - phase transient flow in the downstream tunnel system of spare turbo generator set of Lijia Xia difference equation of characteristics is applied to deal with this transient flow. In this paper, we analyse the water hammer pressures in the upstream conduit and downstream tunnel of the turbo - generator set and the stability of the turbine speed.The effect range of interface surging have been given in this paper.
