Abstract
The three quantities are (1) residual fault current, (2) steady-state recovery voltage, and (3) natural frequency of transient recovery voltage. Loci of constant values of each of these, plotted in rectangular coordinates of degree of zero-sequence shunt compensation versus degree of positive-sequence shunt compensation, are straight lines. The assignment of sets of such constant values gives a family of straight lines. The first family, representing fault current, are parallel and have positive slope. The third family, representing natural frequencies are parallel and have negative slope. The second family, representing recovery voltage, has differing slopes but all lines pass through a common point at coordinates 1,1.Keywords
