FIELD: power engineering. SUBSTANCE: power accumulators are activated in correspondence with proposed method of fast control over power in power generation plant including steam turbine ( 2, 4, б)) and generator 8 setting excessive power (PS) of generator in process of its operation. At least one of parameters of process (PS characterizing operational condition of generation plant is used to achieve especially effective control in agreement with invention to add to generator power P1), (PWL, PFW, MPD, DFD, KL, TB, P), to determine aggregate of specified values of position (Y, DFD).. Gear for realization of method has control device to which inputs values (PS, P1) of power of generator 8 and one more parameter of process (PWL, PFW, MPD, DFD, KL, TB, P), as minimum are fed and its outputs show specified values of position (Y, DFD) of actuating elements connected to steam turbine ( 2, 4, б) ). EFFECT: increased efficiency of control. 11 cl, 2 dwg
