Bucket turbine is a device widely used in the development of high head and small flow hydraulic energy, which converts hydraulic energy into mechanical energy. The mechanical energy output by the water turbine is converted into electrical energy through a generator and then transmitted to the user end through the power grid for use. In order to ensure the quality of electrical energy and the controllability of energy conversion, bucket type water turbines need to be equipped with corresponding regulation and control mechanisms to achieve regulation and control during normal operation of the turbine and emergency shutdown of the turbine in case of accidents, while ensuring the safety of the hydropower station and unit. According to the requirements of hydraulic turbine regulation and control, a hydraulic control system scheme for the bucket type hydraulic turbine governor was designed, including the nozzle and deflector hydraulic control system, and the governor pressure oil station system scheme. The functions of various components of the hydraulic system and the regulation and control action process were analyzed in detail. The results have been applied in a high head hydropower station in Guangxi, China, with excellent performance and good results.
