StartStudy of Impact upon Shipping Conditions of Ship Lock by Load Shedding of Generating Units at Fujinba Hydropower Complex

Fujinba Hydropower Complex is located at a —Ω‖ shaped large curve bend of Fujiang River in Taihe Town of Hechuan City. Both the power plant and the ship lock are located in the same canal at the neck of the curve bend. Impact upon navigation safety of ships sailing in approach channels of ship lock by surge wave of unsteady flow generated during load shedding operation of generating units can not be ignored. Calculation analysis and model study on characteristics of surge wave generated within channel by load shedding of generating units of the power plant are made in the article. Results of the research demonstrate that if surge wave with steep peaks generated in the approach channel during load shedding of the power plant is carried out simultaneously by 2 or more generating units, surge wave in approach channel will exceed the allowable wave height of 0.5m and may endanger navigation safety of ships.
