Design method for nuclear power station reactor control system

Abstract

The invention provides a design method for a nuclear power station reactor control system. The design method comprises that: S1. a Relap5 thermal-hydraulic model and a mathematical model are established; S2. a control scheme is confirmed according to performance indexes of a reactor control system and the mathematical model; S3. a Simulink model is established for the reactor control system; S4. different control parameters are respectively selected in the Simulink model, and transient simulation is completed via the Relap5 and the Simulink and the control parameters are adjusted; S5. whether the simulation result meets the performance requirement of the reactor control system is judged; if the judgment result is no, the process of the method returns to the S2; and if the judgment result is yes, S6 is executed; and S6. setting values of the control parameters are outputted. Design of the reactor control system is realized via the control system modeling simulation method based on the Relap5 and the Simulink, , and design and simulation of the reactor control system, especially setting and optimization of the control parameters, can be flexibly and conveniently completed.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to a design method for a reactor control system of a nuclear power plant. Background technique [0002] The reactor control system of a nuclear power plant is the core of the control of the nuclear steam supply system of the PWR nuclear power plant, and is also the key to the safe operation of the unit. The system contains multiple control processes and the control objects are complex, which is the key and difficult point in the design of nuclear power plants. [0003] The reactor control system mainly includes: power control system, reactor coolant average temperature control system, reactor coolant pressure control system, pressurizer water level control system, steam discharge control system, steam generator water level control system, etc. [0004] The design of the reactor control system generally includes the analysis of the controlled system and the establishment of th...
