Patent Searching and Data


Title:
GASEOUS FUEL COMPRESSING AND CONTROLLING SYSTEM AND METHOD THEREFOR
Document Type and Number:
Japanese Patent JPH10131769
Kind Code:
A
Abstract:

To compress or expand gaseous fuel, and correctly control fuel pressure supplied to a turbo power generator, a flow rate, an exhaust temperature, and a current output by using a spiral flow compressor/turbine formed by integrating with a permanent magnet motor/power generator driven by a torque control inverter.

A turbine 14 having a motor 42 is provided with a gaseous fuel inlet 40 and an outlet 41 for supplying gaseous fuel whose pressure is raised by a nozzle 24 to a combustor 22. An inverter driving device 43, three phase current is supplied to a turbine motor 42 by electric connection 44, and operation speed and a phase data are received by electric connection 45. In an inverter driving device 43, a torque control signal and a maximum speed signal 46 are received from a current control device 15. In the turbo power generator 15, power generator speed and a current feed back signal 47 are received from the inverter driving device 43. In the gaseous fuel inlet 40 and output pressure sensors 55, 54, a data is transferred to the current control device 15 so as to function control.
