PSAT这个软件中有关牛顿-拉夫逊法的源程序代码中DAE.f,DAE.x之类的到底代表什么?
DAE是一个matlab的结构,含义如下DAE differential and algebraic equations, functions and Jacobians matrices. Fields
are as follows:
y algebraic variables y
kg variable for distributing losses among generators
x state variables x
n number of state variables n
m number of algebraic variables m
npf dynamic order during power flow nPF
f differential equations f
g algebraic equations g
Fx Jacobian matrix of differential equations Fx = ∇xf
Fy Jacobian matrix of differential equations Fy = ∇yf
Gx Jacobian matrix of algebraic equations Gx = ∇xg
Gy Jacobian matrix of algebraic equations Gy = ∇yg
Gl Jacobian matrix of algebraic equations Gλ = ∇λg
Gk Jacobian matrix of algebraic equations Gk = ∇kg
Ac complete DAE Jacobian matrix
tn vector of DAE for time domain simulations
t current simulation time (-1 for static analysis) 谢谢!!! DAE是个结构体中,其中主要保存微分代数方程组计算中变量的计算结果,DAE.f代表微分方程组的计算结果,DAE.g代表代数方程组的计算结果,DAE.x代表微分方程组中状态变量的计算结果,DAE.y代表代数变量的计算结果,其他的依次类推。如果你想要掌握这方面的内容,需要先掌握电力系统暂态分析的相关原理,建议你最好看看倪以信老师的《动态电力系统的理论与分析》一书。不然你可能不太容易明白psat里面变量的含义。 我去居然看软件源代码... 不都差不多么. 赞2楼和4楼提供的详细信息! 回复 4# aj_toto
我想我得去看看这本书 我想。我该看看这本书…… 原代码一般怎么理解啊,不太好下手啊,求指教~~~
