METHOD FOR CONTROL OF POWER GENERATION SYSTEM AND DEVICE FOR ITS REALISATION Russian patent published in 2013 - IPC H02P9/00 

FIELD: electricity.

SUBSTANCE: in the method to control a power generation system and a device comprising a generator (3), an aircraft engine (1), a static converter of voltage and frequency (4) on output leads of a control unit (7) control signals are generated in accordance with a law set by microprocessors (9-11), on control leads of which identical voltage meanders are generated with the specified width and frequency, parameters of which may vary depending on the working condition of microprocessors. In each pair of adjacent microprocessors meanders are compared to each other by width and frequency. The result of comparison is supplied to a summator (14). When parameters of meanders divert from each other in at least one of pairs of microprocessors, the summator (14) generates a signal to disconnect a power supply unit (12) from all microprocessors for fixed minimum time τ₁, for which they may resume normal operation. In case of a random failure in one of processors and its reversibility, for the time of supply disconnection the circuit serviceability is resumed. Signals from microprocessors are again compared. If there is no information on recovery of their normal operation within fixed time τ₂ a splitter (2) disconnects a driving shaft of the aircraft engine (1) from the generator (3).

EFFECT: increased quality of output energy without considerable complication of a circuit and with minimum costs.
