ELEKTRISCHE ANORDNUNG FÜR TURBINE/ALTERNATOR AUF GEMEINSAMER ACHSE

摘要

An electrical system for a turbine/alternator comprising a gas driven turbine and permanent magnet alternator rotor rotating on a common shaft and comprising an inverter circuit connected either to an AC output circuit or the stator windings of the alternator. A control circuit during start-up mode connects the inverter circuit to the stator windings of the alternator and during the power generation mode it switches and connects the inverter circuit to the AC output circuit. Thus, during the start-up mode, the alternator functions as a motor to raise the speed of the turbine to a safe ignition speed and in the power generation mode the system provides power through the AC output circuit, electrical power having a frequency and voltage unrelated to the rotational speed of the turbine/alternator.
