分岐水圧鉄管を有する水力発電所における水圧変動について

抄録

We take up the case of hydro-electric power station having a branched penstock, which consists of a main pipe and two branch pipes connected to the main pipe. To each downstream end of branch pipes, water turbines are connected. At water-turbine side, a pressure-wave is generated (caused, for example, by vibration of water column in draft-tube) and this pressure wave propagates along the penstock. The Author has made a theoretical calculation of the distribution of amplitude of this pressure wave, along the length of penstock, for various frequencies and load conditions at turbine side. The result of calculation is shown by graphs.
