堆功率控制系统稳定域及其动态特性研究

Stability and Dynamic Characteristics Study of Research Reactor Power Control System

反应堆功率控制系统是反应堆的核心控制系统。论文对研究堆功率控制系统的稳定性进行了分析，采用了不同的方法求取了使反应堆功率控制系统稳定的减速器的传递系数Ki 的取值范围，并在稳定范围内对功率控制系统进行了动态仿真分析。分析结果表明：使功率控制系统稳定的减速器传递系数Ki 的取值范围为0～16．1263，Ki 越大，系统响应越快，调节时间越短。但Ki 值过大会出现衰减振荡，Ki 取值为0．4时，系统具有较好的动态特性。

Reactor power control system is a core control system of the reactor .The stability of research reactor control system is analyzed .Different methods are used to calculate the reducer transmission coefficient Ki range , the reactor power system is stable in this range .And dynamic simulation analysis of the system is carried out . The analysis result indicates that the reducer transmission coefficient range is 0~16.1263, when Ki is larger, the control system response is faster , and the regulation time is shorter .But as the Ki exceeds one value ,the system will appear damped oscillation .When Ki is 0.4, the system has better dynamic characteristics .
