A method for regulating the power of a turbo set converting thermal power into electric power, said turbo set comprising, on a common shaft, a turbine driven by the thermal power and a generator driven by the turbine and delivering electric power to a network, in which method the electric power delivered by the generator is determined and the thermal power for the turbine is regulated as a function of the measured electric power, wherein, in addition, the kinetic power consumed or delivered by the shaft is determined, and wherein the thermal power is regulated in accordance with the sum of the electric power and kinetic power, wherein the sum of the electric power and kinetic power is compared with a predetermined power value, and the thermal power is reduced, when the difference is positive, and is increased, when the difference is negative and in order to determine the kinetic power, the rotary frequency of the shaft is measured, and the kinetic power of the shaft is calculated from the measured rotary frequency in accordance with the formula Pkin E2 IGIGW PRPHQWRILQHUWLDRIWKHVKDIW
