DEVICE FOR SYNCHRONISATION OF PARAMETERS CONNECTED FOR PARALLEL OPERATION OF GENERATORS Russian patent published in 2015 - IPC H02J3/00 H02J3/40 

FIELD: instrumentation.

SUBSTANCE: device for synchronisation of parameters connected for parallel operation of generators comprises two division devices, two comparators with an actuating element at the outlet, which form jointly the first regulation block, a common subtractor, an amplitude detector connected to the outlet of the reference generator and comprising a differentiator, a subtractor, an integrator, a signal delay element, two multipliers, a block of rooting and two additional amplitude detectors.

EFFECT: increased accuracy of detection of mismatch of amplitudes, frequencies and phases connected for parallel operation of generators and reduced error of synchronisation of these parameters of board network voltage.
