The variable blade hydraulic turbine is a brand new device that utilizes tidal current as the main source of energy. Based on the experimental data of turbine simulation prototype, this paper takes the coe^icient of power （CP） of variable blade tur-bine as the main research subject, analyzes the experimental data by mathematical calculation and statistical comparison, and discuss-es the influence of key parameters on the hydrodynamic performance of the turbine, so as to master the basic operating rule of the variable blade turbine and obtain the most important parameters such as the optimum blade tip speed ratio and the maximum power efficiency of the turbine. This provides a powerful support for the theoretical research and practical application of the new hydraulic turbine.
