PROBLEM TO BE SOLVED: To provide a method for operating a hydraulic turbine enabling operation by setting a large effective head in operation of the hydraulic turbine of a simple structure without a flow rate control guide vane. SOLUTION: An operation stop water level h2 stopping operation of the hydraulic turbine 15 is set in a middle of a conduit 13 giving effective head necessary for operation of the hydraulic turbine. Normal operation rotating an impeller of the hydraulic turbine 15 at rated rotation speed is executed while water level is not less than the operation stop water level. COPYRIGHT: (C)2009,JPO&INPIT
