The object of the invention serves for more efficient acquisition and conversion of renewable forms of energy, such as wind and water power, into electricity, in particular for supplying independent supply districts (isolated operation) and for minimising plant costs. The gear train as designed in the invention divides the power path coming from the prime mover into two power paths for two separate supply systems: - a power path with automatic speed control for driving a small a.c. generator, for priority supply of a base-load system with clean, constant-frequency current; - and a power path for driving a larger generator without automatic speed control for converting the energy arising that exceeds the base demand, for example for heating, producing hydrogen electrolytically, or for other forms of storage. Apart from the advantage of low losses, and thus efficient energy conversion, when only small amounts of energy are available, the construction effort and costs of the supply path with automatic speed control can be kept modest, and the components for converting sporadically occurring excess amounts of energy can be constructed in a robust, inexpensive and reliable manner. |
