Identification Method for Transfer Function of Steam Generator Level Control System of Ling’ao Phase Ⅱ NPP

Science and Technology on Reactor System Design Technology Laboratory, Nuclear Power Institute of China, Chengdu, 610041, China

摘要: 对岭澳核电站二期蒸汽发生器水位控制系统设计过程中未知的被控对象和物理过程传递函数进行辨识研究,给出辨识方法。根据设备特性曲线,利用瞬态分析程序(CATIA2)计算得到瞬态结果。对所得的结果进行分析和数据提取,得到辨识基本数据,然后采用MATLAB程序建立参数估计所需模型,进行参数辨识,最终得到相关传递函数,得到的传递函数满足控制系统总体设计和性能验证的需求。

Abstract: The identification of the unknown transfer function about controlled object and physical process of the steam generator level control system of Ling’ao Phase II NPP was studied and the identification method was given.The basic data used for the identification were obtained by analyzing the feature curves of the device provided by the supplier and the transient results calculated by transient analyzing program CA-TIA2 and extracting the related data.The unknown transfer functions were finally gained using the parameter estimation models built in MATLAB software after getting the basic data.The identification results meet the requirements on the general design and performance verification of the control system.
