Abstract

Model performance test is generally used to design a new hydraulic turbine instead of prototype performance test to save time and cost. The present study verifies the usefulness of model performance test for a prototype turbine design. Three different model turbines were designed and manufactured for a model test, and then the model test was conducted in K-water hydraulic turbine model test center. Reproducibility test was performed to determine the uncertainty of the test results. The standard of a model test was referred to IEC 60193 which is the international standard for a hydraulic turbine acceptance test. A Hill Chart with n11-q11-efficiency was plotted based on the model test results. Furthermore, on-site test was conducted to verify the usefulness of model test by comparing model test results with the onsite test results.
