In the Rod position measure system of reactor on nuclear power plant, the measurement of control rod position measurement provides the basis for the operation safety of the nuclear power station, therefore the accuracy of bar position measurement is very important. This paper start with the data processing , the bar and the secondary coil voltage induced by the application of least squares method to fit the test data according to the different temperatures. Through the comparison of the results of three different segmentation methods, a suitable fitting interval of three sections of polyline is optimized and a three-stage linear regression model is established, and the continuity of the whole section fitting is guaranteed. The results show that the overall measurement accuracy of this modeling method can reach (-5, +4) steps, which can meet the requirements of accuracy very well. |
