Abstract

The formation, development and melt of ice in pumped storage reservoirs in cold climate are studied by numerical simulation. Based on the theory of ice hydrodynamics and the MFC module of Visual C++ 6.0, a mathematical model of ice regime of pumped storage power station in the form of dialog box was established, which includes the hydraulic calculation module, the temperature diffusion module and the ice sheet thermal fluctuation module. The model was applied in Pushihe pumped storage power stations and the results showed that the simulation results were in good agreement with the prototype observation results. The research results can provide effective technical reference for the selection of anti-ice operation mode and the reserve of frozen storage capacity of pumped storage power station in cold area in winter.
