灯泡机组径流水电站全枢纽过渡过程计算研究

The bulb turbine's transient calculation and research of the all hinge of riverbed power station

在与灌溉相结合的灯泡式机组径流水电站系统中 ,其稳态初值的计算和全枢纽过渡过程的计算都是难点 ,而且由于径流式水电站的特殊性 ,有时需要考虑河床涌浪的影响。针对带有灌溉系统并装设灯泡式机组的径流水电站 ,进行了计及涌浪影响的全枢纽过渡过程计算 ,并在稳态初值计算中使用虚拟阻抗法对流体网络进行求解 ;计算及分析了涌浪对枢纽机组过渡过程的影响及由涌浪引起的对枢纽运行机组的水力干扰情况。计算结果表明 ,坝前。

In the bulb turbine of the riverbed power station system in combination with irrigation system, it's difficult to calculate the initial value and the transient, and for the particularity of the riverbed power station, sometimes the effect of the ground swell need to be taken into account. For this reason, this paper puts forward the method of virtual resistance to calculate the initial value of this system and to calculate the transient considering the effect of the ground swell. Meanwhile, this paper also researches the effect of the ground swell on the transient and the running bulb turbine. The results showed that the ground swell 's effect is evident on the transient.
