Zusammenfassung:	A method for stably operating a lean fuel intake gas turbine engine by controlling the rotation speed of the lean fuel intake gas turbine engine for which it is difficult to control the rotation speed by controlling a fuel flow rate, is provided. In a method for operating a lean fuel intake gas turbine engine (GT) configured to use, as a fuel, a combustible component contained in a low-concentration methane gas to drive a power generator, a power converter (17) is provided between an external electric power system (19) and the power generator (11), and a rotation speed of the power generator (11) is controlled by the power converter (17), to control a rotation speed of the gas turbine engine (GT).
