| abstract | PROBLEM TO BE SOLVED: To provide a hydroelectric power generation facility capable of maintaining an optimum operating state even when an inlet pressure changes. SOLUTION: A turbine 1, an induction generator 2, an inverter 3, a valve control device 5 that controls a motorized valve 4, an inlet pressure converter 6, and an outlet pressure converter 7, and the inverter 3 is connected to an inlet pressure signal Pin The calculation means 321 for calculating the effective head hr of the water wheel from the outlet pressure signal Pout, the data storage device 323 that records the hr and the optimum rotational speed Nap as a function, the Nap obtained by using the hr, and the output of the inverter The valve control device 5 has a calculation means 53 for calculating the hr, a data storage device 51 that records the maximum effective head hmax and the reference input pressure Psin, Comparing and calculating means 52 for comparing the data from the data storage device 51 and the data from the calculating means 53 to determine the opening / closing direction of the motor-operated valve 4, The inverter 3 controls the generator 2 so that the Nap for the hr becomes the Nap.
