AI Technical Summary
In the existing technology, the data correction method for the secondary loop system of nuclear power units is easily affected by significant errors, resulting in inaccurate correction results and difficulty in correcting significant errors online.
A robust data correction model is constructed using robust estimation theory. Robustness is evaluated through robust estimation function and influence function. Correction is performed by combining flow measurement variable data and estimation of unmeasured variables. Data correction is performed using the law of conservation of mass and variable constraints.
During the steady-state operation of the secondary loop system of a nuclear power unit, the impact of random and significant errors should be reduced to provide accurate data correction results and improve the reliability and accuracy of the data.
