<p><P>PROBLEM TO BE SOLVED: To provide an engine generator capable of preventing excessive reaction of the rise of the speed of an engine and engine start and converging the engine speed quickly when a failure is sensed. <P>SOLUTION: The engine generator 15 is equipped with a power generator 11 driven by the engine 1, an inverter device 12, and a control device 14. The engine 1 is equipped with an actuator 6 to control the supply amount of a gas fuel supplied from a fuel supply means 2, a governor 7 to make feedback control of the output for the actuator 6 on the basis of an engine speed command given by the control device 14, and a first changeover device 8 to changeover between disconnection of the governor 7 and actuator 6 from each other and the start of their connection. At normal times, the first changeover device 8 is put in the start of connection, and the output to the actuator is feedback controlled by the governor 7. At the time of failure, setting is made so that the first changeover device 8 is turned into disconnection and the specified output is given directly to the actuator 6. <P>COPYRIGHT: (C)2004,JPO</p> |
