Mutual Coupling

Mutual coupling of transmission system segments enables the user to couple (or parallel) multiple transmission segments together, provided that their lengths are all identical.  In the past, this was possible only by manually combining two or more separate systems of towers (or cable cross-sections) into the same transmission segment.  Now PSCAD can be programmed to perform this task automatically, and even toggle between coupled and non-coupled states, all the while maintaining the individuality of each segment.

 

Mutual coupling can also circumvent certain node mapping issues when dealing with multi-phase wires and buses. For example, you can now couple multiple transmission segments connected to the same bus, without the need for Breakout components!
