Power System Toolbox Updates

Version 3.0 17 November 2008

To day I found that the file ml_sig was set to a apply a signal. You should alter the file to the following:

function f = ml_sig(t,k)

% Syntax: f = ml_sig(t,k)

%4:40 PM 15/08/97

% defines modulation signal for lmod control

global lmod_sig n_lmod

f=0; %dummy variable

if n_lmod~=0

lmod_sig(:,k)=zeros(n_lmod,1);

%lmod_sig(:,k) = 0.1*randn(n_lmod,1);

%if t>=0.0

% lmod_sig(1,k)=.1;

%end

%elseif t>0.2

% lmod_sig(:,k)=zeros(n_lmod,1);

%end

end

return

pstv3 will be updated shortly.

I have revised and combined the loadflow and dynamics manuals. The new version of PST has additional models and was originally developed for my book ‘Power System Oscillations’.

Send in Bug Reports

Please send in any bug reports. This sort of feedback is essential to program development. Unfortunately, programs such as PST are very difficult to debug. Users' system data may often call code in an unanticipated way. The data sets supplied with PST are quite varied, and these have been used to check the programs performance, but quite rightly users want to do more.

When you send in a report, please supply the data that you were using when the problem was noticed. Email seems to be the best communication medium, so please send your reports to cherry@eagle.ca.
