【 摘 要 】

The HydroHillChart software is a complex one used to calculate the hill chart for hydraulic turbines. The application was developed in the Python programming language, while the mathematical tool used for interpolation is the cubic spline type function. The paper presents the HydroHillChart - Kaplan module application, used to calculate the hill chart of the Kaplan hydraulic turbine models, by processing the data measured on the test rig. The hill chart expresses graphically the functional dependence of the Kaplan turbine parameters (n11, Q11, ao, η) and is the instrument on which the industrial turbine is designed. This dependence arises from extensive experimental research carried out on Kaplan turbine models, leading to a library of optimized characteristics for the specific flows and heads of these turbines types.
