Electrical system for turbine/alternator on common shaft |
摘要 |
An electrical system for a turbine/alternator comprising a gas driven turbine and permanent magnet alternator rotating on a common shaft comprises an inverter circuit connectable either to an AC output circuit or the stator winding of the alternator. A control circuit during a startup mode switches the inverter circuit to the stator winding of the alternator and during a power out mode switches the inverter circuit to the AC output circuit. Thus, during the startup mode, the alternator functions as a motor to raise the speed of the turbine to a safe ignition speed and in the power out mode the electrical system outputs to the AC output circuit, electrical power having a frequency unrelated to the rotational speed of the alternator.
