Embodiment Construction

[0099] Now in conjunction with example, accompanying drawing the present invention is further described:

[0100] like figure 1 As shown in the figure, the present invention is a modular modeling and simulation method for the secondary circuit of a nuclear power system, which decomposes and simplifies the complex thermodynamic process of the secondary circuit of the nuclear power system into different systems and processes, and calculates them separately in different modules to ensure accurate simulation. While improving the efficiency of modeling, the separation of the calculation process of different modules is also conducive to the further improvement and optimization of each module;

[0101] The method includes the following steps:

[0102] Step 1: According to the flow of working fluid in different equipment, the secondary circuit system is decomposed into the following four subsystems: steam turbine system, which provides driving power; condensing equipment system, whic...

Abstract

The invention discloses a modular modeling and simulation method for a secondary circuit of a nuclear power system. The main steps are as follows: 1. Decompose the secondary circuit system into the following subsystems: a steam turbine system, a gas condensing equipment system, a steam pipeline system, and a water supply system; 2. . Decompose the process in the thermodynamic system into three processes: fluid flow, heat transfer and mechanical energy transfer; 3. Determine the operating parameters and structural parameters of each subsystem; 4. Establish the dynamic model of each subsystem; 5. Connect the subsystem models , carry out the overall simulation calculation of the secondary circuit; 6. After the calculation is completed, output the calculation result. The invention divides the secondary circuit system into different equipment according to different energy conversion principles, and then divides the equipment into different modules according to different characteristics of the thermal process, so as to realize the modular modeling and simulation of the secondary circuit system, and ensure the accuracy of the simulation. Under the premise of improving the efficiency of modeling, it provides convenience for the optimization of the system model in the future.

Description

technical field [0001] The invention belongs to the technical field of nuclear reactor systems, in particular to a modular modeling and simulation method for a secondary circuit of a nuclear power system. Background technique [0002] As a steam power conversion system, the secondary circuit system of a nuclear power plant directly affects the reliability and economy of the entire nuclear power system during the operation of the nuclear power plant. Therefore, establishing the dynamic model of the secondary loop system, researching and analyzing its operation under various unsteady conditions is of great significance to the research and design of nuclear power plants, and the formulation of operating procedures and automatic control strategies. The secondary circuit of the nuclear power system is a large and complex thermal system composed of several power machinery, connecting pipelines, heat exchangers and other auxiliary systems. Under the action, it enters the main driv...
