This section contains zero-sequence mutual coupling parameters of transmission lines. The first line in the section must say: [MUTUAL DATA]. This is followed by the data described below. A blank line ends the section.
The mutual data is aggregated into “mutual groups”, each of which may be up to 900 lines. Each group must begin with the ‘groupSize=’ keyword and ends with the ‘endGroup’ keyword. The number that follows the ‘groupSize=’ keyword is the number of lines in the group. This number must be greater than 1 and less than, or equal to, 240.
Between the ‘groupSize=’ and ‘endGroup’ keywords must be the data for n(n-1)/2 of mutual coupled pairs, where n is the number of lines in the group. The data format of each mutual coupled pair is described below.
Note: Users of OneLiner V14.5 and later can make use of the alternative format for mutual coupling data, which start with text line [MUPAIR DATA] and does not require “mutual groups” aggregation. Simply include in this section data of all mutual pairs with non-zero R or X in the format described below.
