The invention can be used for wind power and hydro power engineering for the provision of an additional supply of additional supply AC electric energy and other types of energy such as heat energy to consumer. The aim of said invention is to increase the efficiency factor of an electric power installation whose motor has a variable frequency and/or a variable shaft power. The inventive energy conversion method can be used first and foremost for a non-autonomous electric power installation whose motor shaft is mechanically connected to rotors of at least two electric generators (1, 2) having correspondingly n-phase and m-phase stator windings (n can not be equal to m). A part of electric energy produced by the windings can be converted into another type of energy in an electric energy storage device (12). A part of electric energy produced by at least one generator (1, 2) can be supplied to a consumer only when the rotor speed corresponds to the frequency of current used by the consumer and produced by windings (3-5). The stabilisation of said rotor speed is carried out by breaking or terminating and varying the current sink on the electric energy storage device (12) simultaneously for all phases of at least one generator which is connected to the consumer, and/or of individual phases of at least one generator which is disconnected from the customer. |
