| 摘要 |
The invention relates to a drive train for transmitting a variable power at a variable input speed for a power- generating station that is driven by a turbomachine such as a wind turbine (3) or a water turbine. Said drive train comprises a power-split transmission (5) for distributing the power to at least one first power branch (7) and at least one second power branch (7). The first power branch (7) at least indirectly drives an electric generator (11) while a connection is established between the first power branch (7) and the second power branch (18) by means of a hydrodynamic circuit (12) which is disposed at the output end of the power-split transmission (5). The power flow is influenced in such a way by the hydrodynamic circuit (12) that the speed at which the electric generator (11) is driven is substantially constant. |
