In the whole-system dynamic simulation platform, a variety of control equations, physical models and solution methods are applied to establish the simulation module design of these components. Afterwards, dynamic simulation platform of the Brayton cycle is formed by integrating these components, and then the platform is verified and validated. Monitoring of 5 types of system data, the platform can simulate 2 kinds of steady state and 4 kinds of transient operation conditions of the system as well as 2 kinds of the accident conditions, which includes reactivity insertion accidents and loss of cooling air accidents so that it can obtain the operating characteristics of the system under different operating conditions as well as the dynamic response process. This can help to understand the dynamic changes of key parameters of the nuclear reactor power system in the process of operation, and to predict and identify the problems that may occur in the system. In addition, various safe operation control strategies and load-following control strategies are proposed for the Brayton cycle of the nuclear reactor power system, and a full-range load-following method of the system from 100% to 0% is realized. In this way, data for the training of the intelligent control system of SIMONS could be provided.
