Designing Pump-Turbines for Tongbai in China

摘要

Construction of the 1,224-MW Tongbai project in China required development of four reversible pump-turbine units. To achieve the optimum design for this facility, contractor VA Tech Hydro employed a variety of techniques, including using computational fluid dynamics modeling to determine the profile geometry and performing numerical flow simulation of different operating points. The units now are operating reliably.
