蒸汽發(fā)生器水位自抗擾控制方法研究
發(fā)布時間：2022-01-16 10:15
U型管蒸汽發(fā)生器（UTSG）是壓水堆（PWR）中最常見的部件之一,所以需要對U型管蒸汽發(fā)生器的性能進行精確的仿真,以分析各種設(shè)計和運行參數(shù)對核電站性能的影響。UTSG是一類非線性、不確定、非最小相位和時滯系統(tǒng)。進水溫度和其他不確定因素對UTSG的控制提出了很大的挑戰(zhàn)。針對上述問題,本文分析了兩類系統(tǒng)（線性系統(tǒng)和非線性系統(tǒng)）,對不同區(qū)域和參數(shù)的U型管蒸汽發(fā)生器進行了數(shù)學(xué)建模。其中一個模型將所有行為線性化,使用6個變量;另一個模型包括數(shù)學(xué)模型中的所有非線性變量,使用9個變量。本研究主要有兩個目的。第一:利用MATLAB/SIMULINK對UTSG的兩個系統(tǒng)進行建模,并研究這些系統(tǒng)在穩(wěn)態(tài)和瞬態(tài)條件下的行為。第二部分:對UTSG數(shù)學(xué)模型的水位系統(tǒng)進行檢測和控制設(shè)計。UTSG對瞬態(tài)條件（擾動如:給水質(zhì)量流量,蒸汽壓力和溫度）的響應(yīng)在蒸汽發(fā)生器安全評估中起關(guān)鍵作用。本文討論了所有這些響應(yīng)并且得出了結(jié)果。提出了自抗擾控制技術(shù)（ADRC）用于控制目的,解決水位跟蹤問題,并在一些變化過程中主動抑制固有動態(tài)和外部擾動基于ADRC。在MATLAB/SIMULINK環(huán)境下實現(xiàn)了自抗擾控制器（ADRC）和傳統(tǒng)控...
