FIELD: electrical engineering.
SUBSTANCE: in the method for synchronizing synchronous generators, input signals proportional to the difference between the instantaneous phase voltages of like phases of the mains operating generator and the connected generator, are squared, and then summed using an adder. Output of the adder is compared with the set voltage level. If the set voltage level exceeds the voltage value of the output signal of the adder, a pulse is formed at the output of the comparator, on the leading edge of which a signal is generated for the activation of the current switch of the connected generator.
EFFECT: increase in sensitivity and accuracy of determination of the moment when the signal for the activation of the current switch of the connected generator is sent.
