Abstract

The invention discloses a numerical model processing method for simulation of a digital instrument control system of a nuclear power plant. The numerical model processing method comprises the steps of: a) firstly, determining important input signals of the digital instrument control system of the nuclear power plant by comprehensively analyzing the main performance indexes or requirements of the digital instrument control system of the nuclear power plant; and b) then according to the input signals and relevant digital sampling module parameters of the digital instrument control system of the nuclear power plant, modifying a numerical model of a simulated program, i.e. respectively increasing digital sampling module models and relevant sampling time steps to the input signals and setting relevant processing time steps for control channels. By conducting digital processing to the instrument control system in the simulated program, the digital instrument control system can be simulated more really and can be optimized, the goal of guiding actual design through simulation researches is achieved, the simulation result is used for guiding field debugging and power operation, and the availability, the reliability and the economy of the nuclear power plant are improved.
