(read only)


This property returns Flag that indicates if elements of the System Y have been changed by recent activity.


Example


% Create DSS object

DSSObject = actxserver('OpenDSSEngine.DSS')

if ~DSSObject.Start(0),

                    disp('Unable to start openDSS');

                    return

end;

DSSText = DSSObject.Text;

DSSCircuit = DSSObject.ActiveCircuit;

% Compile a model        

DSSText.Command = 'Compile C:\myPath\myModel.dss';

DSSSolution = DSSCircuit.Solution;


% Set load multiplier 1.1

DSSSolution.LoadMult = 1.1; 

% Set max control iterations to 100

DSSSolution.LoadMult = 100; 

% Set max solution iterations to 20

DSSSolution.MaxIterations = 20; 

% Set simulation step size (sec)

DSSSolution.StepSize = 1;


% solves the circuit including

DSSSolution.SolveSnap();


% check if the SystemY has changed

if DSSSolution.SystemYChanged,

                    disp('The Y bus matrix has changed');

end;
