TURBOCHARGER ELECTRIC GENERATING DEVICE

摘要

A turbocharger electric generating device (1) generates electricity with a generator (7) by driving a gas turbine (3) and a compressor (6) with the exhaust gas from an internal combustion engine (2). The AC power that is generated is supplied to a power system (12) via a power conversion means (8). The power conversion means (8) is equipped with: a converter (13) for converting AC power to DC power; a means (18) for estimating a rotor rotation angle ¸ on the basis of a rotor magnetic flux; and a control means (15) for performing coordinate transformation of an AC current to a DC current on the basis of the rotor rotation angle ¸, and controlling the DC power outputted by the converter (13) in such a manner that the size of the DC current is maintained at a target DC current value.
