Experimental and numerical study on self-sustaining performance of a 30-kW micro gas turbine generator system during startup process

The safe startup of micro gas turbine (MGT) generator system is the premise normal operation. whole start-up process contains motor startup, ignition, speed acceleration, switching to and power acceleration. Motor happens at self-sustaining state, which significant process. However, characteristics MGT state are hardly investigate due lack performance maps complete experiments. Therefore, this work analyzed schedule presented a theoretical experimental study on system, based self-designed 30 kW built in Jiangjin Turbocharger Plant, China. boundary fuel consumption area determined from aspects startup. A novel principle for determining point (SSP) proposed. Results show that can be achieved only when over 26,750 rpm, SSP 30,750 rpm proposed principle. Finally, TIT natural flow compared with data, two relative errors both almost within 4%. This method instructive
