| 摘要 |
The turbine has an inlet tube directed against the water flow and towards the water surface, a turbine housing containing a nozzle control mechanism and running wheel, a suction tube (5) leading from the housing base to below the water, and an air delivery valve (7) above the center of the turbine rotor. Each nozzle control mechanism's control drive has an opening angle sensor (11). The opening angle sensors, a generator (G) revolution rate sensor (13) and a generator effective power sensor (14) feed signals to a microcomputer (30), which controls the drive for the air delivery valve via a digital control transducer. |
