Abstract
A gaseous fuel compression and control system is disclosed which utilizes a helical flow compressor/turbine integrated with a permanent magnet motor/generator and driven by a torque controlling inverter to compress or expand gaseous fuels, precisely control fuel pressure and flow, and precisely control the operations (speed, combustion temperature and output power) of a gaseous fuel fired turbogenerator.
Claims36
A gaseous fuel compression and control system, comprising:
- a turbogenerator set including a turbogenerator and turbogenerator power controller, said turbogenerator including a compressor, a turbine, a combustor with a plurality of gaseous fuel nozzles and a plurality of air inlets, a recuperator, and a permanent magnet motor/generator;
- a helical flow compressor/turbine for supplying pressurized gaseous fuel to the gaseous fuel nozzles of said turbogenerator combustor, said turbogenerator compressor supplying compressed air to said air inlets of said turbogenerator combustor;
- a motor operably associated with said helical flow compressor/turbine to drive said helical flow compressor/turbine;
- and
- a helical flow compressor/turbine motor inverter drive operably associated with said helical flow compressor/turbine motor to provide electrical power to said helical flow compressor/turbine motor and receive operational data from said helical flow compressor/turbine motor, said helical flow compressor/turbine motor inverter drive also operably associated with said turbogenerator power controller to receive control signals from said turbogenerator power controller, said turbogenerator power controller also receiving operational data from said helical flow compressor/turbine motor drive inverter and turbogenerator parameter signals from said turbogenerator.
