Abstract

The invention relates to a simulation method and system based on nuclear power system operation. The method comprises the following steps: acquiring actual operation data of a subsystem in a nuclear power system; constructing a sub-task simulation model of the subsystem and determining influence factors of the sub-task simulation model of the subsystem; determining estimated values of the influence factors by utilizing fluid mechanics, heat transfer science and an automatic control principle; judging whether the estimated value is a correction value or not; if the estimated value is not the correction value, performing parameter optimization by using a swarm intelligence optimization algorithm to obtain an optimal value of the influence factor; correcting the sub-task simulation model of the subsystem by using the optimal value of the influence factor; determining a task simulation model of the nuclear power system according to all the corrected sub-task simulation models of the subsystems; determining a corrected task simulation model of the nuclear power system; and simulating the operation of the nuclear power system by utilizing the corrected task simulation model of the nuclear power system. According to the invention, the accuracy and the working efficiency of simulation of nuclear power system operation are improved.

Description

technical field [0001] The invention relates to the simulation field of nuclear power system operation, in particular to a simulation method and system based on nuclear power system operation. Background technique [0002] With the development of modern simulation technology, the requirements for model accuracy are getting higher and higher. The safety and economy of nuclear power unit operation require that nuclear power plants must be equipped with high-precision nuclear power plant simulators. Equipment modeling errors occur when the equipment model does not fully reflect the equipment itself. At the same time, during the operation of the nuclear power plant, as time goes by, the characteristics of the pipe network and other equipment such as resistance, heat transfer coefficient, and operating point may change, so the uncertainty introduced will make the original simulation The model cannot accurately reflect the actual operating conditions of the main coolant system an...
