【 摘 要 】

The three-dimensional curved surface of "working head-output-efficiency" of turbine generating set needs to be modified dynamically in real time because of the small amount of data at the initial stage of measurement and the change of efficiency after long-term operation. A data preprocessing method is presented. The processed sample data can not only filter out the measurement noise, but also track the real efficiency change of the turbine generator set. Three correction conditions have been worked out, and the three-dimensional curved surfaces will be corrected after the correction conditions are satisfied. The field demonstration project proves that it can ensure the accuracy of efficiency curved surface of turbine generator set and provide accurate data for optimal load distribution.
