Inability to synchronize power generators either means you are doing it wrong, or there is something wrong, some malfunction.

Synchronization procedure depends on the particular design, but the generalized procedure is to match voltage and RPM, with the second (to-be-synchronized) generator slightly higher in both voltage and RPM, and close the circuit right at the point of synronization as indicated on a synchronometer. Immediately after closing the circuit, you want to bring the excitaion voltage and power input up, so as to take load, otherwise the second generator will become a load instead of a generator.

This procedure works in the normal case where the first generator is much larger than the second generator, i.e. the first generator is a power distribution grid. Cases where two equal generators are being synchronized are different. Again, consult the documentation.

If the procedure is being followed correctly, then you need to troubleshoot.

Basically,so that the phases of the induced emf are the same i.e in-phase,and that the frequencies are the same. Otherwise the induced emf will be lendered irrelevant.
