Key Words: micro-turbine generator; dynamics simulation, operation mode transfer. ABSTRACT The micro-turbine generator unit is superior to the traditional synchronous generator unit in many aspects; for example, a variety of fuels (e.g. anaerobic methane) may be used. So it is deemed one of the most promising green power sources. Three modes of operation are available for the unit: island, grid-connected and multi-machine modes. To be able to operate in all three modes, it’s a better choice for the unit to adopt the P-f droop mode of control. For a unit with such a control mode, dynamic simulation analyses for operation mode transfer are made in this paper. It is shown that significant transient power disturbance will be induced when the unit is transferred from the island mode to the grid-connected mode. When two units simultaneously connect to a grid, the impact on both units will be even more serious. The degree of impact is not less than the impact on a traditional synchronous generator unit that is subjected to a three-phase-to-ground fault. ༬ċણӤ Ὦʷ֓ɿֱ Ὦɺቅ ᖁߡʪ֓ɼ౺ 11 Journal of Technology, Vol. 23, No. 1, pp. 11-20 (2008)
