The algorithm of confidence level of DCCT system for SSRF

In this paper,we report our work on the method of data reliability assessment of the DC curreny transformer(DCCT) system of SSRF.In order to predict the true value of parameter of DCCT system,the Kalman filtering model for the DCCT system is established.Through statistical analysis of the DCCT data,the confidence threshold is defined,and real time confidence level of the DCCT data is provided with a computer code.In this way,availability of the DCCT system has been improved.
