Vibration and Flow Characteristics of a 200 MW Kaplan Turbine Unit under Off-Cam Conditions
Kaplan turbine units can adjust their blades to achieve wider outputs without a Suction Vibrators significant loss of efficiency.The combination of guide vane angle (GVA) and blade angle (BA) is selected based on efficiency curves obtained from cam tests.However, the vibration characteristics are not considered in the test.The vibration and flow ch
