This work presents an alternative approach for deriving an unconventional distance protection algorithm suitable for long single-circuit transmission lines. Such approach is based on the application of Kirchhoff’s laws to a system modeled in the frequency domain. The electric power system considered and the steps of the protection algorithm deduction approach are detailed. As a result, the same input signals from the literature are obtained, which demonstrates the adequacy of such methodology to different systems.
