Study on the physical simulation of transient process in conduits of hydropower stations

The transient process in the conduits of hydropower stations is a very complicated dynamic procedure coupled with fluid,machines,electricity,and even structure.The current methods used to analyze them separately cannot satisfy the design and the operation requirements of those large underground stations with long conduits.So it is necessary to develop a global physical simulation for the power station transients.As an initial discuss,this paper focuses on the introduction of model scale of similarity,integral simulation with fluid,machines and electricity,transients control and measurement,and some experimental results about great fluctuation,small fluctuation and hydraulic interference in transient process.The comparison of experimental and computational results is presented in this paper.
