To close a oneline diagram, select Close Oneline from the File menu, right-click on the background of the oneline diagram and select Form Control > Close from the local menu, or click the Close button on the oneline itself. This will prompt you to save the oneline if changes have been made since the last save. Note that this does not close the current case, just the oneline diagram. The power system data is still loaded, and case simulations can be run with the oneline closed.
