信号107によって水位調整装置103に送られている。In such a water level adjusting device 103, the no-load flow rate at which the guide vane should be fully closed (opening 0%) from the reference water level and the water level droop rate (the full load flow at which the guide vane should be fully opened (opening 100%)) Of the guide vane provided at the entrance of the water turbine 105 (see FIG. 2), and sends an opening / closing command to the guide vane. In this case, the current opening degree of the guide vane is sent to the water level adjusting device 103 by the return signal 107.

このようにガイドベーン開度を調整して流入量と水車

ある。At this time, in the above-mentioned pouring type regulating pond, the reference water level and the water level droop rate are generally fixed (value).

きない。Here, when trying to apply the water level adjustment device of the above-mentioned conventional regulating pond type hydroelectric power plant to a dam, the dam has a very large volume compared to the regulating pond, there is a seasonal water level fluctuation, and the dam water level is high. When the time is low, the ratio of the change in the water storage amount to the change in the water level is different, so that it cannot be applied as it is.

ため、ダムからの放流量が０の場合、同じ流入量に対す
る水位変動は大きく水位垂下率が大きい。In other words, referring to FIGS. 5 and 6, since the dam is in the form of a bevel unlike the regulating pond, the dam water storage amount is not proportional to the water level. For example, when the discharge amount from the dam is set to 0, the water level changes at point A and point B, which have different water levels, even if the inflow amount is the same. Therefore, the water level droop rate must be changed according to the water level. That is, since the dam surface area is large when the water level of the dam is high, when the discharge amount from the dam is 0, the water level fluctuation is small and the water drop rate is small if the inflow into the dam is the same. On the other hand, when the water level is low, the surface area of the dam is also small. Therefore, when the discharge amount from the dam is 0, the water level fluctuation for the same inflow is large and the water level droop rate is large.

As a result, the water level of the dam is controlled by adjusting the opening degree of the valve, so that when the water level of the dam changes, the reference water level is calculated using the water level droop rate corresponding to the changed water level to open the valve. The degree can be controlled, and even if the water level of the dam changes in response to the season or rainfall, the water level after the change is stabilized, and the turbine can be rotated stably to generate power.
