The Diagnosing of the Fouling on Flow Path of Steam Turbine based-on Regression Measurement of Main Steam Flow

摘要：

The main steam flow measurement model based-on Fulugel formula is not exact, it is susceptible to change of flow path. A model based-on support vector regression is presented, the results show that the presented model has powerful prediction precision and generalization, it is not be affected by the area change of flow path, And we can determine whether the flow path is scaling by comparing the regression results with measurement data. The result shows that the method has high precision and possesses certain practical application significance, and provides a new analysis method of main steam flow and flow path situation.
