The Communications Networks and Systems in Substations
protocol (IEC 61850) enables a new networking approach
for power system automation in substations. Traditional
communications were geared around slow transmission
speeds, which constrained the rate of data flow and forced

expensive, mostly manual basis. IEC 61850 was designed

capacity and speed enables automated control actions that
are initiated by computers in the substation rather than by a
