In order to ensure the bearing oil film is not damaged during the shutdown process of the units at Bulunkou Hydropower Station, to maintain the unit tile temperature within a safe range, and to solve the braking shutdown issue, this paper, taking the Bulunkou Hydropower Station in Xinjiang as the background, introduces the engineering application of flexible electrical braking technology in impulse turbine units. It focuses on the shutdown methods of impulse turbine units at Bulunkou Station, the principle of flexible electrical braking shutdown, the wiring form of the main electrical braking circuit, the electrical braking process, the main parameters of the electrical braking system's equipment, and discusses the basic ideas and engineering implementation of flexible electrical braking technology.
