Hydraulic Transients in the Long Diversion-Type Hydropower Station with a Complex Differential Surge Tank
Based on the theory of hydraulic transients and the method of characteristics (MOC), a mathematic model of the differential surge tank with pressure-reduction orifices (PROs) and overflow weirs for transient calculation is proposed. The numerical model of hydraulic transients is established using the data of a practical hydropower station; and the probable transients are simulated. The results ...
متن کاملNumerical Simulation of Hydraulic Transients in Rijeka HPP
Original scientific paper In this work a new approach considering numerical modelling of waterhammer dissipation and attenuation is proposed. The classical Allievi liquid flow model has been extended with the Brunone unsteady friction model which includes separation of the local and convective unsteady friction factor. A widely-adopted approach in solving this model is treatment of the unsteady...
متن کاملSimulation Modeling for Electrical Switching System of Hydropower Station
This paper proposes a simulation modeling method for the electrical switching system of hydropower station, which is a sub-topic for Hydropower Station Simulation Training System. The graphics model of commonly used electrical switch equipment is developed with a certain software [1]. As vast and different types of Hydropower station circuit breakers and associated grounding switches, and each ...
متن کاملThe Numerical Simulation for air distribution of an Underground Main Workshop in Hydropower Station
ABSTRCT: Use CFD method to study of the air distribution of certain practical project. By using three-dimensional RNG k-εturbulent model, the air distribution of an underground main workshop in hydropower station with heat source at non-isothermal condition has been designed by means of numerical simulation. Solve the controlling equations by using the soft ware of computational fluid dynamics ...
متن کاملExperimental and Numerical Simulation of Water Hammer in Water Conveyance Pipeline and Effect of Surge Tower Pipe in Controlling this Phenomenon
Water hammer is one of the unsteady flows in urban water distribution networks, which has been of great importance due to the damage caused to the pipeline and has always been of interest to researchers. In this study, the phenomenon of water hammer due to the sudden closure of the valve in the downstream end has been investigated in a laboratory and using a numerical model. In the laboratory s...
