HIGH-PRECISION AND HIGH-FIDELITY REAL-TIME SIMULATION AND BEHAVIOR PREDICTION METHOD AND APPARATUS FOR NUCLEAR POWER PLANT

摘要

A high-precision and high-fidelity real-time simulation and behavior prediction method and apparatus for a nuclear power plant. The method comprises the steps of: (1) constructing a nuclear power plant simulator and a physical nuclear power plant on the basis of the same design parameters; (2) operating the nuclear power plant simulator and the physical nuclear power plant in parallel, and acquiring, in real time, prediction parameters output by the nuclear power plant simulator and operating parameters of the physical nuclear power plant; (3) comparing, one by one, the prediction parameters and the operating parameters representing the same physical quantity, and correcting a prediction model in the nuclear power plant simulator and input parameters of the prediction model by means of a large-scale concurrent-parallel parameter search correction algorithm and a pattern recognition correction algorithm based on artificial intelligence, until the prediction parameters reach a specified accuracy; and (4) according to set operating conditions, operating the nuclear power plant simulator to acquire the prediction parameters, and thereby completing behavior prediction of a physical nuclear power plant system. Compared with the prior art, the method has advantages such as a high prediction accuracy and a high parameter authenticity.
