WATER SUPPLY SYSTEM GENERATOR SET

PROBLEM TO BE SOLVED: To provide a water supply system generator set capable of quickly stopping a hydraulic turbine without setting limitation in the operation of a water supply system. SOLUTION: A hydraulic turbine bypass conduit 17 including a bypass valve 18 is provided in parallel with a hydraulic turbine water supply conduit 13. A valve open and close operation device 19 closes a hydraulic turbine start valve 15 of the hydraulic turbine water supply conduit 13 and opens the bypass valve 18 to make a water quantity flowing in the hydraulic turbine water supply conduit 13 bypass the hydraulic turbine bypass conduit 17 according to the close operation of the hydraulic turbine start valve 15 when a stop signal of the hydraulic turbine 14 is inputted. After the hydraulic turbine start valve 15 is fully closed, the device opens a flow rate adjusting valve 12 to make the water quantity flowing through the bypass valve 18 flow to the flow rate adjusting valve 12 of the water supply conduit 11, and closes the bypass valve 18 according to the open operation of the flow rate adjusting valve 12.
