A method for using a high-reliability hydroelectric generating set, characterized in that: A high reliability hydroelectric generating set as claimed in any one of claim 9, comprising the following steps: S1: Startup preparation: Check whether the filter screen (10005) installed inside the water inlet (10001) of the dam (100) is clean and unobstructed. If there is any debris, it should be cleaned up in time to prevent it from entering the turbine system and damaging the equipment. Check whether the generator (108) and its related electrical connection lines are normal to ensure normal power transmission; S2, equipment operation: the electric valve (102) is opened through the controller (120), so that water enters the turbine cover (104) through the connecting pipe (101) and the water inlet pipe (103), and the water flow impacts the turbine blades (115), so that the drum (113) rotates, and the transmission shaft (109) at the top of the drum (113) transmits power to the generator (108), and the generator (108) starts to generate electricity; S3, water flow monitoring: controlling the flow velocity sensor (10004) to operate through the controller (120), and calculating the appropriate angle adjustment value of the turbine blade (115) by combining the water flow velocity data of the water inlet (10001) detected by the flow velocity sensor (10004) with the design operating parameters of the turbine; S4, blade adjustment: the motor (11205) in the adjustment mechanism (112) is started by the controller (120), the motor (11205) drives the connecting shaft (11202) to rotate, the worm (11204) on the connecting shaft (11202) meshes with the worm wheel (11203) on the adjustment rod (117), thereby causing the adjustment rod (117) to rotate, and the second bevel gear (119) at the bottom end of the adjustment rod (117) cooperates with the first bevel gear (118) on the rotating shaft (116), thereby adjusting the angle of the turbine blade (115) to an angle suitable for the current water flow conditions.
