The steady-state performance of low frequency AC (LFAC) systems for bulk power transmission is proposed and investigated in this paper. It is demonstrated that the LFAC is superior to the conventional 60 Hz AC system in terms of power transfer capability and voltage stability. An existing power system can increase its power transfer capability by up to more than eleven times if it operates at 5 Hz...
The low frequency AC (LFAC) transmission, in which a power system is operated at a low frequency, i.e., below 50/60 Hz, is superior to the conventional 60 Hz system in terms of power transfer capability. In addition, due to low operating frequency, the line reactance is reduced and thus voltage drops along the line are decreased. The low frequency transmission thus offers a higher voltage profile...
