The presented paper deals with doubly fed machines (DFM) operating in units that convert mechanical energy to electric power and vice versa. We concentrate especially on their usage in pumped storage plants which, used in the power system, can increase its stability and operating efficiency. Even a small change of speed from the synchronism can increase the efficiency of the energy conversion by almost 10% and reduce the unfavourable effects of turbine cavitation.
