Research of Micro-gasturbine Generator

Article of Honda R&D Technical Review Vol.15 No.2


Research on a micro gasturbine generator targeted for a compact distributed energy resource, which would contribute to the improvement of energy usage efficiency, has been conducted. While aiming at a low emission level by introducing a premixed lean burning method, the engine has achieved a generation efficiency of 30.8 and 26.7 percent at the engine and system end respectively by adopting a recuperator and by reducing the heat and mechanical loss specific to its compact structure. Electricity output from the high-speed generator is converted into commercial power and supplied in coordination to the power grid. The engine, inverter and other auxiliary devices have been arranged into one compact package, achieving the highest performance and ambience level in the class (of 40 kilowatts). Further modifications of the engine have improved the efficiency to 32.9 percent at the engine end.
