Abstract:Existing waterturbine efficiency calculation methods and their problem were introduced. The process of to realize realtime online analyzing waterturbine efficiency was discussed. Waterturbine efficiency calculation formula, input data collection method, input data effectiveness estimation, result tolerance analysis and other problem were emphasized. Calculation instantaneity and effectiveness were achieved. A new approach to exam waterturbine efficiency was indicated.

Keywords:water turbine, efficiency calculation, formula, tolerance analysis
