稳压器的模型化与仿真

本文提出了完善的核电站稳压器三区不平衡模型及相应的PZR-1动态仿真程序。程序分别采用了亚当斯(Adams)方法、哈明(Hamming)方法、龙格-库塔(Rang-Kutta)法和外推法等不同算法,仿真精度高、速度快。以希平港核电站减负荷试验时稳压器的动态特性对模型和程序进行验证,仿真结果与试验数据符合良好,结果同时表明用亚当斯方法进行仿真更有效。

Modeling and Simulation of Pressurizer

A perfect nonequalibrium three region pressurizer model and its corresponding dynamical simulating program PZR-1 with accuration and high speed are presented in this paper. Adams method, Hamming method, Rang-Kutta method and extrapolation method are adopted in the program. PZR-1 is employed to simulate the Shippingreport pressurizer at loss-of-load experiments. Simulating results agree well with the experimental data and indicate that Adams method is more efficient.
