| 中文摘要 | 流体网络实时仿真计算涉及大型稀疏非线性“病态”方程组的求解问题,是电站实时仿真建模中最复杂的计算问题之一。针对方程的非线性特性,基于Newton-Raphson方法,提出了一种改善收敛特性的迭代方法。改进后的方法具有大范围收敛特性。针对Jacobi矩阵的特点,采用有效的稀疏矩阵方法求解矩阵方程,以保证仿真的实时性。基于物理概念,给出了小流量及“孤岛”情况下“病态”Jacobi矩阵的数值处理方法。; The simulation of fluid network involves issues of non-liner, large, sparse matrix and stiff equations, and perhaps is the most challenging task in the plant simulation. Based on characteristics of non-linear equations, an improved iteration method is put forward in this paper, with a good convergence property as compared with the original Newton-Raphson method. An efficient spare matrix algorithm is also used to guarantee the simulation process to have a real time nature. The method dealing with the "stiff" problem occurred in the zero flow path and isolated islands is discussed. |
