Abstract: In a method for regulating the power of a turbo set (10) converting thermal power into electric power, said turbo set (10) comprising, on a common shaft (17), a turbine (11) driven by the thermal power and a generator (16) driven by the turbine (11) and delivering electric power (PG) to a network (18), the electric power (PG) delivered by the generator (16) is determined and the thermal power (PT) for the turbine (11) is regulated as a function of the measured electric power (PG). Destabilization of the network and overloading of the turbo set (10) are avoided by additionally determining the kinetic power (Pkin) consumed or delivered by the shaft (17) and by regulating the thermal power (PT) in accordance with the sum of the electric power (PG) and kinetic power (Pkin).
