Error in SwtControl function in OpenDSS

[Zhraso]

Hello All,

I want to consider a switch on a line using following code for a modified IEEE 13-bus system with a new line added. I define a switch on the new line using:

New SwtControl.680675 SwitchedObj=Line.680675 SwitchedTerm=1 Action=Open Lock=Yes Delay=0 Normal=Open

However, when I run the code the line is still close. How can I open Line.680675 ?

Also, I want to consider three switches for Line.680675 (i.e., one switch for each phase of the line), How can I define one switch for each phase of this line and control them independently?

Thanks

Here is the code:

Hello,

The problem is simple, when disabling the control actions (Controlmode=OFF) the controllers, including the SwtControl, will not operate. If what you want to do is to open the line with no control actions, use the command "Open":

Open Line.671692 1

To close it back, use the command "Close" in the same way.

Best regards

Davis
