I want to multiply admittance matrix of power electronic converter(PEC) in m.file of matlab,First i want to multiply matrix admittance of circuit to vector of
current
source to achieve nodal voltage.
the current source is dependent to voltage of node, so the vector of
current source should be updated in simulation time.
i want to implement the circuit in M.file
How i can begin to write in m.file?
you can use this code for admittance calculator :
sh=input(' please enter the number of buses : ');
ybus=zeros(sh,sh);
y1bus=zeros(sh,sh);
for i=(sh-1):-1:1
for j=(i+1):+1:sh
a=sprintf('Plz enter Y%d%d ... ?',i,j);
disp(a)
ybus(i,j)=-input('... ? ');
ybus(j,i)=ybus(i,j);
end
end
for i=1:sh
a=sprintf('Plz enter Y%d%d ... ?',i,i);
disp(a)
y1bus(i,i)=input('... ? ');
ybus(i,i)=y1bus(i,i)-sum(ybus(i,:));
end
disp('Admittans matrix : ');
disp(ybus)
disp('Impedance matrix : ');
zbus=inv(ybus);
disp(zbus)
clear y1bus a j i sh;
If you know programming, maybe it is better to have a quick look at a book about Matlab and m.file.
I couldn't exactly understand what you want to do, but regarding the fact that Matlab is a useful tool for doing operations on matrices and vectors, it is clear that the thing you want to do is really easy to implement on Matlab.
Just have a brief review on a book related to Matlab and matrices operators and functions on Matlab.
