蒸汽发生器水位自抗扰控制方法研究
发布时间:2022-01-16 10:15
U型管蒸汽发生器(UTSG)是压水堆(PWR)中最常见的部件之一,所以需要对U型管蒸汽发生器的性能进行精确的仿真,以分析各种设计和运行参数对核电站性能的影响。UTSG是一类非线性、不确定、非最小相位和时滞系统。进水温度和其他不确定因素对UTSG的控制提出了很大的挑战。针对上述问题,本文分析了两类系统(线性系统和非线性系统),对不同区域和参数的U型管蒸汽发生器进行了数学建模。其中一个模型将所有行为线性化,使用6个变量;另一个模型包括数学模型中的所有非线性变量,使用9个变量。本研究主要有两个目的。第一:利用MATLAB/SIMULINK对UTSG的两个系统进行建模,并研究这些系统在稳态和瞬态条件下的行为。第二部分:对UTSG数学模型的水位系统进行检测和控制设计。UTSG对瞬态条件(扰动如:给水质量流量,蒸汽压力和温度)的响应在蒸汽发生器安全评估中起关键作用。本文讨论了所有这些响应并且得出了结果。提出了自抗扰控制技术(ADRC)用于控制目的,解决水位跟踪问题,并在一些变化过程中主动抑制固有动态和外部扰动基于ADRC。在MATLAB/SIMULINK环境下实现了自抗扰控制器(ADRC)和传统控...
