PURPOSE:To improve follow response by providing a deviation output signal from a water level controller to preceding and following machines and operating with same guide vane opening. CONSTITUTION:A water level regulating signal to be led to a water level controller 13 can be shown by (A+B)/2 assuming that the guide vane opening detection signal of first water turbine generator 27 is A while that of second turbine generator 28 is B, then on the basis of said signal, water level detection signal and water level setting signal a motor operation setter 14 is operated to slide the sliding position of potentio meter 16 from fixed terminal side 16c to fixed terminal side 16d thus to improve follow response. |
