Multiple characteristic curves processing technology for large scaled hydraulic turbines scheme design based on basic element model

To improve efficiency of scheme design for large-scale hydraulic turbines,reasonable organization of design knowledge and its intelligent design made valuable contributions to design tasks.After describing the design knowledge with basic element,the basic element implication model of running selection and the data storage model were presented.And then,an improved searching and matching method of key points in running area was put forward,based on these,the data smooth model and the basic element interaction and judgment model of key points in running area were presented.Finally,an example of large-scale hydraulic turbines scheme design was provided to validate the efficiency and feasibility of the proposed models.
