A power generation device (1) includes: a power generator (10), a power conversion circuit (21), a first interruption circuit (23), a second interruption circuit (24), a first monitoring circuit (25) which monitors an output current flowing from the power generator (10) to the power conversion circuit (21) and outputs a first interruption signal when an absolute value of the output current exceeds a first predetermined value, and a second monitoring circuit (26) which monitors a total value of output voltages of respective phases of the power generator (10) and outputs a second interruption signal when an absolute value of the total value exceeds a second predetermined value. A first interruption circuit (23) electrically interrupts a connection between the power generator (10) and the power conversion circuit (21) in accordance with the output of the first or second interruption signal, and the second interruption circuit (24) electrically interrupts the connection between the three-phase coils (Lu, Lv, Lw) and the neutral point (N) in accordance with the output of the first or second interruption signal.

An aircraft turbine engine including at least a propulsion shaft and an electric motor. A rotor is rigidly connected to the propulsion shaft. The electric motor includes at least three power channels, a control device designed to determine a control parameter for each power channel on the basis of a control command, and a correction device designed to correct a precession movement of the rotor relative to the stator. The correction device being designed to determine the control command of the control device from a setpoint command and a precession level. The control command being designed to generate a global magnetic force opposing the precession movement of the rotor so as to damp said movement.

A gas turbine generator system configured to be electrically interconnected to an electrical grid via a first circuit breaker. The gas turbine generator system includes a compressor configured to output a pressurized gas flow to an electrically heated thermal energy storage system which outputs a heated and pressurized gas flow to a gas turbine to cause the gas turbine to rotate and drive an electrical generator. The electrical generator outputs electric power to the electrical grid via the first circuit breaker, operating in a normally closed position. There is a controller to detect an opening of the first circuit breaker and to close a first switch, in response to the opening of the first circuit breaker. The first switch is connected to the output of the electrical generator and to the electrical input of the electrically heated thermal energy storage system, connecting the generator to the thermal energy storage system.
