The increasing energy needs give rise to a steady interest innew sources of energy, in particular, in the energy of the WorldOcean: tides, surf, waves, water temperature difference betweenthe surface and deep layers of the ocean, and flows.The use of the naturally renewable energy of the sea tidesto transform it into other forms of energy, mainly electrical, liesat the heart of the work of tidal power plants (TPP).Despite a number of advantages of using TPP (significantreserves of the used type of energy; the invariance of its magnitudein the monthly (seasonal and multi-year) periods during thethe entire lifetime of the TPP; independence from the water volumeduring the year, etc.), the energy of tides is still not used to thefull, due to its relatively high cost and limited availability ofplaces with fairly high tides.The analysis of the peculiarities of the tidal power plants,found that one possible way to improve their efficiency, it is touse in synchronous generators with excitation from permanentmagnets with high specific energy, which will simplify the designof capsular units, thereby increasing their efficiency.The replacement of electromagnetic excitation by the useof magnetic systems with permanent magnets makes it possibleto simplify the rotor design, to exclude sliding contacts, to reducelosses by eliminating them in the rotor winding.The results and proposed evaluation algorithms can be usedto determine the PTT parameters and its aggregate part, as wellas the main dimensions of the generators with the specified construction(with excitation from permanent magnets used in theaggregates).
