<p><P>PROBLEM TO BE SOLVED: To obtain a gas-turbine power generation facility capable of supplying stable, good quality electric power to a load and that does not degrade the lifetime of a battery. <P>SOLUTION: A generator 3 is driven by a micro gas turbine 5, the generated electric power is converted into DC power temporarily by a converter 7, and the DC is converted into AC power again by an inverter 8 and supplied to a plurality of loads via a load switching device 21. A load selecting and controlling device 19 controls the load switching device 21 based on the power P of the generator 3 and prevents the overload of the generator 3 by switching the power supply from the generator 3 to a part of loads 17 and from a system 24 to the remaining loads 17. Thus, good quality power can be supplied to the loads without causing the quality deterioration of power including a voltage drop arising from overload limitation of the generator. Also, the degrading of the lifetime of the battery can be prevented that is caused by frequent charges and discharges that occur along with the supply of auxiliary power from the battery when limiting the load of the generator. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
